I'm trying to pip install a library that has a lot of dependencies. I have a patched version of one dependency that I would like not updated when I install the library. How can I prevent this patched dependency from being updated?
(Specifically, I want to pip install fastai without upgrading my version of torch, but do install other dependencies required)
If you install this dependency before running pip install it won't install it again.
This means to you can install your patched version and then your package:
For instance:
From pypi with another version
pip install requests==2.17.0 pip install kinto From a Git branch
git clone [email protected]:kennethreitz/requests.git pip install -e requests pip install kinto From a egg or a wheel
wget https://github.com/kennethreitz/requests/archive/v2.21.0.tar.gz pip install v2.21.0.tar.gz pip install kinto 
As of 2024 (CPython 3.12.2, pip 24.3.1), the Natim's answer does not seem to work. I ran
pip install torch==2.5.0 pip install torchvision and this automatically upgraded torch to 2.5.1. What worked for me is to pass the --no-deps argument to pip:
pip install torch==2.5.0 pip install torchvision --no-deps But the problem of this solution is that I may accidently update torch with some other package that uses it as a dependency, in the future...
