There are a few reasons I can think of to have offline pip packages:
|
|
|
|
- A package isn't able to compile on a friend's computer since they don't have the million linear algebra libraries that `numpy` /`scipy` require.
|
|
- You want to archive everything to run a piece of software
|
|
- You want to control the packages available to a closed network
|
|
|
|
Regardless, to my surprise, setting up a repository of python wheels doesn't take many steps.
|
|
|
|
## Setup
|
|
|
|
First I would recommend that you setup a virtual environment. Either through [pyenv](https://brandonrozek.com/blog/pyenv/) or [python-virtualenv](https://brandonrozek.com/blog/virtualenv/).
|
|
|
|
Then, install whatever packages you would like. Let us use tensorflow as an example:
|
|
|
|
```bash
|
|
pip install tensorflow
|
|
```
|
|
|
|
We're going to need the packages `pip-chill` and `pip-tools` for the next couple steps
|
|
|
|
```bash
|
|
pip install pip-chill pip-tools
|
|
```
|
|
|
|
After you install all the packages you want to be available, freeze the requirements that aren't dependencies to a text file
|
|
|
|
```bash
|
|
pip-chill --no-version > requirements.in
|
|
```
|
|
|
|
We will then use `pip-compile` in `pip-tools` to resolve our dependencies and make our packages as fresh as possible.
|
|
|
|
```bash
|
|
pip-compile requirements.in
|
|
```
|
|
|
|
To sync the current virtual environment with the `requirements.txt` file that gets produced
|
|
|
|
```bash
|
|
pip-sync
|
|
```
|
|
|
|
Now we have a fully working and resolved environment.
|
|
|
|
From here, we need to install the wheel package to make the binary wheels.
|
|
|
|
```bash
|
|
pip install wheel
|
|
```
|
|
|
|
Then to create the wheels,
|
|
|
|
```bash
|
|
pip wheel --wheel-dir=wheels -r requirements.txt
|
|
```
|
|
|
|
With this you have a whole repository of wheels under the wheels folder!
|
|
|
|
## Client Side
|
|
|
|
Now you can get [all fancy with your deployment](https://realpython.com/offline-python-deployments-with-docker/#deploy), though I just assumed that the files were mounted in some shared folder.
|
|
|
|
The client can install all the wheels
|
|
|
|
```bash
|
|
pip install /path/to/wheels/*
|
|
```
|
|
|
|
Or they can just install the packages they want
|
|
|
|
```bash
|
|
pip install --no-index -f /path/to/wheels/wheels package_name
|
|
```
|
|
|
|
