How to Transfer Ollama Model Settings Between Hugging Face Models

Brisbane Web Developer — Sun, 13 Jul 2025 01:25:29 +0000

Situation

I had a model called hf.co/aaa/Example-XXX:YYY in Ollama, and I found the model at Hugging Face.

Today, I found a fine-tuned model and tried to use it, but noticed that ollama show does not show TEMPLATE etc, and the output is unexpected (e.g. It does not stop answering etc).

Say, ollama pull names the fine-tuned model as:
hf.co/bbb/FineTuned-Example-XXX:Q4_M.

And you decided to apply the same settings from:
hf.co/aaa/Example-XXX:YYY.

Commands

# Delete the model downloaded
# - I did this, but you can actually keep it and just replace it
#   with a new configuration
ollama rm hf.co/bbb/FineTuned-Example-XXX:Q4_M

mkdir my_modelfiles

cd my_modelfiles

ollama show --modelfile hf.co/aaa/Example-XXX:YYY > example.txt

# Amend "example.txt" to say:
# FROM hf.co/bbb/FineTuned-Example-XXX:Q4_M

# Create the model with the modified file:
ollama create hf.co/bbb/FineTuned-Example-XXX:Q4_M -f example.txt

# Check the model:
ollama show hf.co/bbb/FineTuned-Example-XXX:Q4_M

# Run the model:
ollama run hf.co/bbb/FineTuned-Example-XXX:Q4_M "Hello."

Avoid an extra message from not using Amazon Bedrock when running the fabric command

Brisbane Web Developer — Sun, 29 Jun 2025 02:51:23 +0000

Summary

I noticed that the recent fabric (v1.4.219, while I was writing this) displays an extra output when:

You run the command
You have the file $HOME/.aws/credentials
Your AWS credential does not have the permission for Amazon Bedrock (as I do not use it).

fabric -L
---
Bedrock failed to list foundation models: operation error Bedrock: ListFoundationModels, https response error StatusCode: 403, RequestID: 12345678-1234-1234-1234-123412341234, AccessDeniedException: User: arn:aws:iam::123412341234:user/example is not authorized to perform: bedrock:ListFoundationModels because no identity-based policy allows the bedrock:ListFoundationModels action

Available models:

Ollama

        [1]     ...
        [2]     ...
(Omitting)

Workaround

I cloned their Git Repository, asked GitHub Copilot + ChatGPT 4.1 why the extra unexpected message, and figured that it refers to an environment variable AWS_SHARED_CREDENTIALS_FILE so that if I set something, the current code sees as you have a legitimate AWS credential, thereby avoiding the output:

$HOME/.config/fabric/.env

(Omitting)
AWS_SHARED_CREDENTIALS_FILE=.

Amend Location Changer not working with macOS Sequoia (macOS 15.0 (24A335))

Brisbane Web Developer — Tue, 24 Sep 2024 11:37:04 +0000

Summary

Location Changer stopped working after updating to macOS Sequoia (macOS 15.0 (24A335)).
Found that it gets this message You are not associated with an AirPort network. when fetching the current Wi-Fi network name.

Solution

This takes longer time to retrieve the current Wi-Fi network name, but I have not found another way so far.

1. Install jq for the next step:

brew install jq

2. Revise the way to extract the current Wi-Fi network

system_profiler SPAirPortDataType displays the current network connection details and the option -json does in JSON format which is easier to extract the Wi-Fi network name:

/usr/local/bin/locationchanger::Around the line 16
======
SSID=`system_profiler -json SPAirPortDataType | jq -r '.SPAirPortDataType[0].spairport_airport_interfaces[0].spairport_current_network_information._name'`

How to amend files in WP-Engine with VS Code

Brisbane Web Developer — Mon, 24 Jun 2024 11:28:49 +0000

Summary

I started using VS Code Extension ftp-simple because it let me amend the file directly.
It is useful if you do not have to work with Sass (Their environment does not provide the commands node or git).

Example Settings

Create a new SFTP Setting at WP-Engine Environment.
- Read this bit and the next section "Add SFTP User" about how to do that
At VS Code, press Ctrl + Shift + p and then select ftp-simple : Config - FTP connection setting.
Make sure of setting sftp to type.

[
  {
    "name": "Example Staging Website",
    "host": "examplestg.sftp.wpengine.com",
    "port": 2222,
    "type": "sftp",
    "username": "examplestg-example",
    "password": "exampleexampleexampleexample1234",
    "path": "/",
    "autosave": true,
    "confirm": false
  },
  {
    "name": "Example Live Website",
    "host": "example.sftp.wpengine.com",
    "port": 2222,
    "type": "sftp",

How to install docker-compose 2 for Debian bookworm

Brisbane Web Developer — Wed, 10 Apr 2024 13:28:03 +0000

Summary

I cannot install docker-compose-v2 via apt command for Debian bookworm.

Solution

Create the package by myself and install it by using some tools.

Steps

Install update-golang

mkdir -p /usr/local/src/github.com/udhos/update-golang
cd /usr/local/src/github.com/udhos/update-golang
git clone https://github.com/udhos/update-golang .

# Run with non-root user with "sudo"
# - Error happens otherwise
# - Latest version of Go for Debian bookworm was 1.19,
#   but the further steps required Go 1.22.1(?)
#   so that I installed the latest version
RELEASE=1.22.2 sudo ./update-golang.sh

Install "makdeb" command

bash -ci "$(wget -qO - 'https://shlink.makedeb.org/install')"

Create the package docker-compose_2 and install it

mkdir /usr/local/src/mpr.makedeb.org/docker-compose
cd /usr/local/src/mpr.makedeb.org/docker-compose
git clone https://mpr.makedeb.org/docker-compose .

When I was doing this, it tried to install Go 1.19 and its decencies so that I disabled the line:

PKGBUILD
======
# makedepends=('golang-go>=1.17')

and I installed only the decencies:

sudo apt install libpkgconf3 pkg-config pkgconf pkgconf-bin

and then created the package:

makedeb -si

and then installed the package:

sudo dpkg -i docker-compose_2.26.1-1_amd64.deb

and then confirm if it is installed by running docker compose instead of docker-compose:

$ docker compose version
Docker Compose version v2.26.1

How to use VS Code Remote SSH with WP Engine

Brisbane Web Developer — Sat, 11 Mar 2023 14:09:06 +0000

Summary

UPDATE : Other co-workers do not want to deal with Git so that now I use ftp-simple.

UPDATE : I kind of stopped using this way after other people started touching the same environment. Another reason I stopped doing this is that it is troublesome to compile Sass files and then upload it. It is better to do the dev work in your local environment with Git and then push it to WP-Engine's remote repository (Another page explaining about that).

So I wanted to use VS Code Remote SSH to amend the files in WP Engine, and I could not have done it even though the file /usr/local/etc/ssh/usermode_sshd_config looks they let me do that.

# Tried this by using 2 SSH connections and that did not work
ControlMaster yes
LocalForward 127.0.0.1:12222 127.0.0.1:2222
======
channel 2: open failed: administratively prohibited: port forwarding is disabled for 127.0.0.1:2222

And therefore, I decided to attempt to establish SSH Reverse Port Forwarding from WP Engine to an Extra Server, and then use VS Code Remote SSH to connect to WP Engine through the Extra Server because I discovered that WP Engine has ssh command :

[VSC Remote SSH]--->[Your PC]--->[Extra Server]--->[WP Engine]

Although that method worked, the preparation is troublesome. It may be better to use another VS Code Extension such as SFTP or do the coding work at another environment. ~~Additionally, note that the connection gets cut off after 10 minutes :~~

~~WP Engine uses a sandboxed SSH “sidecar” that sits alongside your server with a timeout of 10 minutes.~~

UPDATE : I included ServerAliveInterval to ~/.ssh/config and that solved above issue.

UPDATE : I kept using VSC Remote SSH for awhile to do the dev work with WP Engine because I prefer applying the same way to do the dev work, and I have not got an issue so far.

Requirements

You can access WP Engine via SSH on the terminal.
Another host, Extra Server, allowing you to SSH from WP Engine.
Although, this is fundamentally a copy-and-paste solution, you must be able to assemble this information to fit your own.

Steps

Add a new user at Extra Server to SSH from WP Engine

This user is used only for this purpose. If you want to reuse the existing user, you can skip this step.

sudo su -

# "rbash" restricts the user to perform things
adduser --shell /bin/rbash --ingroup nogroup wpe_pf

# Restrict the user more
cd /home/wpe_pf
chown root:root .bash_logout .bash_profile .bashrc .profile
# "readonly PATH=xxx" is like "const PATH = xxx;"
# restricting what the user can see
# ($HOME/bin does not exist)
echo "readonly PATH=$HOME/bin" > .bash_profile
echo "export PATH" >> .bash_profile

The following setting may make above redundant, but just in case:

/etc/ssh/sshd_config
or
/etc/ssh/sshd_config.d/101-wpe_pf.conf
======
# Avoid the user for WP Engine to do much but SSH
Match User wpe_pf
  PermitTTY no
  X11Forwarding no
  PermitTunnel no
  GatewayPorts no
  # This does not work with "/bin/rbash"
  # ForceCommand /usr/sbin/nologin

service ssh reload

exit

Create a new SSH Key

This key is used to connect to the Extra Server from WP Engine. If you want to reuse the existing key, you can skip this step.

ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519.wp-engine-example -C "example@example.com"

Include what ~/.ssh/id_ed25519.wp-engine-example.pub has to the file ~/.ssh/authorized_keys on Extra Server.

Place 2 files at WP Engine

To begin, SSH to WP Engine via the terminal.

Copy the private SSH key ~/.ssh/id_ed25519.wp-engine-example to /sites/example/_wpeprivate/id_ed25519.wp-engine-example, and then run :

chmod 400 /sites/example/_wpeprivate/id_ed25519.wp-engine-example

and then create a new script (where ssh-ed25519 AAAAAAAAAAAA... represents your public SSH key) :

/sites/example/_wpeprivate/ssh-reverse-pf.sh
======
#
# The copy of this script may be better to be kept in your PC
# in case you copied a WP Engine Environment from the one not having this script
#
# Location of the SSH file in WP Engine
SSH_AUTH_FILE=~/.ssh/authorized_keys
# SSH Private Key for Extra Server
SSH_IDENT_FILE=/sites/example/_wpeprivate/id_ed25519.wp-engine-example
# SSH Public Key for WP Engine
# Using the same key for Extra Server would be easier to manage
# because this script may get wiped out when copying the environment
# and the source environment does not have this script
SSH_PUB_KEY='ssh-ed25519 AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA example@example.com'
SSH_SERVER=my_user@my-server.com
SSH_PORT=12222

chmod 600 $SSH_AUTH_FILE && \
echo "$SSH_PUB_KEY" >> $SSH_AUTH_FILE && \
echo "Establishing Reverse Porting Forwarding" && \
ssh -C -o StrictHostKeyChecking=accept-new -i $SSH_IDENT_FILE -R 127.0.0.1:$SSH_PORT:127.0.0.1:2222 $SSH_SERVER

and then change the permission :

chmod 700 /sites/example/_wpeprivate/ssh-reverse-pf.sh

and log out from WP Engine.

Amend ~/.ssh/config

Host *
  PermitLocalCommand yes

Host wp-engine
  HostName example.ssh.wpengine.net
  User example
  IdentityFile ~/.ssh/id_ed25519.wp-engine-example
  Compression yes
  ServerAliveInterval 60
  RequestTTY yes
  LocalCommand ssh-keygen -R "[localhost]:12222"
  RemoteCommand /sites/example/_wpeprivate/ssh-reverse-pf.sh
Host extra-server
  HostName extra-server.com
  User my_user
  IdentityFile ~/.ssh/id_ed25519.wp-engine-example
  Compression yes
  LocalForward 127.0.0.1:12222 127.0.0.1:12222
Host wp-engine-pf
  HostName localhost
  User wpe-user
  Port 12222
  IdentityFile ~/.ssh/id_ed25519.wp-engine-example
  StrictHostKeyChecking accept-new

Note : If you need to handle multiple WP Engines, you may need to create multiple settings. For each additional setting, use a different port number instead of "12222" (which is used as an example in this article).

Log in WP Engine

ssh wp-engine
# OR
# Keep running with the infinite loop
# in case "ServerAliveInterval" does not work
# because it gets cut off every 10 minutes...?
while true; do ssh wp-engine; sleep 2; done

Above "ssh" command establishes SSH connection to WP Engine and then runs the script ssh-reverse-pf.sh to establish another SSH connection to Extra Server.

That another SSH connection is initiated by WP Engine and it creates the port forwarding as to forward the data from Extra Server to WP Engine (SSH Server in WP Engine). Thus, it is called Reverse Port Forwarding as WP Engine initiates the SSH connection but the port forwarding is in other way round :

# "ssh" command
[Your PC]---SSH--->[WP Engine]
# The script "ssh-reverse-pf.sh"
[WP Engine]---SSH--->[Extra Server]
[Extra Server]---Port Forward--->[WP Engine]

Log in Extra Server

ssh my-server

This SSH is to forward the data from VS Code Remote SSH to Extra Server so that the extension can SSH to WP Engine :

[Your PC]------>[Extra Server]------>[WP Engine]

Connect to WP Engine with VS Code Remote SSH

Have the setting Remote.SSH: Enable Remote Command ticked.
SSH to Your PC (with wp-engine-pf in this example).

[VSC Remote SSH]--->[Your PC]--->[Extra Server]--->[WP Engine]

ToDo

Create my first VS Code Extension who does the things above once the settings are created...?

Avoid AutoRaise to activate the window while pressing down the Command Key

Brisbane Web Developer — Sat, 14 May 2022 15:45:02 +0000

UPDATE: The author of AutoRaise spent time to take care of the issue I encountered initially. And therefore, what I initially tried to avoid is no longer an issue. However, I got another situation so that I am still applying this hack to my laptop.

UPDATE: After I sent the Pull Request with this amendment, I was told to try mouseStop=true, and that kind of works, but it's not perfect so that I am using both the feature and my amendment at the moment.

Summary

I use Bartender and AutoRaise (installed via Homebrew), and the window usually gets activated by AutoRaise when I want to select the icon in Bartender's hidden menu bar.
I decided to avoid AutoRaise to activate the window while I am pressing the command key.

With above amendment, I can select the icon in Bartender's hidden menu bar as follows:

Move the mouse to the menu bar.
Show Bartender's hidden menu bar and then press the command key.
Keep pressing down the command key until the mouse cursor reaches to the icon.
Release the command key.
Click the icon (The icon doesn't move to the menu bar and shows the sub menus if you kept pressing down the command key).

This hack avoids AutoRaise to get activated while pressing the command key so that it gets easier to reach to the window when there is another window on the path in some cases (You may not need this hack if the distance between the windows is close enough with the parameter mouseStop).

How To Install via Install Script

This command downloads the install script and then executes it :
Remove AutoRaise from System Preference > Security & Privacy > Accessibility > Privacy at first.

curl 'https://raw.githubusercontent.com/brisbanewebdeveloper/AutoRaise/77-make-it-work-with-bartender-custom/install-custom-version.sh' | sh
# OR
# curl 'https://raw.githubusercontent.com/brisbanewebdeveloper/AutoRaise/latest/install-custom-version.sh' | sh

How To Install Manually

This is what above install script does in case you prefer installing manually.
Remove AutoRaise from System Preference > Security & Privacy > Accessibility > Privacy at first.

# Create the source directory
# ("myUser" is to be your own username)
mkdir -p /Users/myUser/src/brisbanewebdeveloper/AutoRaise
cd /Users/myUser/src/brisbanewebdeveloper/AutoRaise

# Download the custom version
git clone git@github.com:brisbanewebdeveloper/AutoRaise.git .
git checkout 77-make-it-work-with-bartender-custom
# OR
# git checkout latest

# Build the customised program
make clean && make CXXFLAGS=-DALTERNATIVE_TASK_SWITCHER

# Overwrite the one installed via Homebrew
# (Using "ditto" because "cp" command can get error)
chmod 555 AutoRaise
sudo ditto AutoRaise /opt/homebrew/opt/autoraise/bin/

# Remove the files downloaded
rm -fr /Users/myUser/src/brisbanewebdeveloper

# Restart with the custom program
brew services restart autoraise

How To Uninstall

Just reinstall the program:
