Installation Issues with pip

[fbourke]

I've been trying to install torchlensmaker but it appears to have some dependency issues that prevent installation: I first tried
pip install torchlensmaker.git which results in the following:

pip seemed to fail to build package:
    torchlensmaker

Some possibly relevant errors from pip install:
    ERROR: Cannot install torchlensmaker==0.0.1, torchlensmaker==0.0.10 and torchlensmaker==0.0.7 because these package versions have conflicting dependencies.
    ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

Error installing torchlensmaker.

I second tried pip install git+https://github.com/victorpoughon/torchlensmaker.git@main which resulted in the following:

pip seemed to fail to build package:
    notebook>=7

Some possibly relevant errors from pip install:
    ERROR: Could not find a version that satisfies the requirement torch~=2.4.1 (from torchlensmaker) (from versions: 2.6.0)
    ERROR: No matching distribution found for torch~=2.4.1

Error installing torchlensmaker from spec 'git+https://github.com/victorpoughon/torchlensmaker.git@main'.

Hey! Thanks for trying out the project 😃

The command you should use is pip install torchlensmaker to get the latest release (which is currently 0.0.10).

I also highly recommend that you do it in a clean virtual env using venv directly or a tool like uv. My guess is you're trying to install into an environment which has existing dependencies like notebook already installed.

Thank you for your reply!

I made a typo in my initial post, I was indeed using pip install torchlensmaker. I've now installed uv, set up a brand new venv, and tried both pip install torchlensmaker and pipx install torchlensmaker — same dependency error.

(lensmaker-uv) % pipx install torchlensmaker
Fatal error from pip prevented installation. Full pip output in file:

I got it to install! It seems like my default python version of 3.13 might be too new? uv didn't work for me, despite trying to set up a venv with Python 3.11, but pyenv did. Not sure why.

I had to do the following:

brew install pyenv
pyenv install 3.11
#add pyenv lines to rc file and restart shell
pyenv shell 3.11
pip install torchlensmaker

Nice! Feel free to reach out or open another discussion if you have any questions. This is a very early version of the project so expect some rough edges still 😁

I haven't tried it with python 3.13 so yeah, might be an issue there. I'll look into it.

[victorpoughon]

Yeah, looks like pytorch only supports python 3.9 to 3.12 currently. https://pytorch.org/get-started/locally/
