I'm trying to install kornia using poetry.
System details
- Python 3.8.5 (I have to use this version)
- poetry 1.1.13 (upgrading to v1.2 is not an option)
I've previously installed kornia (poetry add kornia) but for some unknown reason I'm now getting the following traceback:
RuntimeError
Unable to find installation candidates for nvidia-cudnn-cu11 (8.5.0.96)
at ~.poetry\lib\poetry\installation\chooser.py:72 in choose_for 68│ 69│ links.append(link) 70│ 71│ if not links: → 72│ raise RuntimeError( 73│ "Unable to find installation candidates for {}".format(package) 74│ )
Since this wasn't a very helpful traceback I thought I'd try to pip install to see if I could get kornia installed somehow, then repeat the process using poetry.
First I ran poetry run pip install nvidia-pyindex, then poetry run pip install kornia. kornia was installed, giving me confidence that I might be able to do the same using poetry.
So I ran poetry add nvidia-pyindex which installed, but when I ran poetry add kornia I got the same RuntimeError.
I wondered if having poetry add without pip uninstall might have caused issues. So I started from scratch - I ran:
rm -rf ~/.cache/pypoetry/cache/repositories/pypi/
poetry rm {name of venv}
git checkout master pyproject.toml poetry.lock
poetry add nvidia-pyindex
which created the venv (by the same name as previously - not sure if this is an issue in itself, since the name of the venv was first created in PyCharm and I wonder if there are some files lingering in places I don't know that is the root of my problems?), then poetry add kornia but got the same error.
I also tried to clear poetry's cache as suggested here but that didn't help. I didn't find a solution here. I don't believe this applies since poetry was installed properly and is working fine otherwise. I read through this but didn't see any working solution. I tried a fix mentioned here, which was to add
[[tool.poetry.source]]
name = "nvidia"
url = "https://pypi.ngc.nvidia.com"
secondary = true
to pyproject.toml, hoping that it would avoid the error when poetry tries to install nvidia-cudnn-cu11, but it didn't help either.
I tried poetry add nvidia-cudnn-cu11 and poetry add nvidia-cudnn-cu116 hoping that having added the ndvidia repo as a secondary source would get kornia's dependencies installed before trying to install kornia itself.
{I don't know if secondary sources are only used when poetry adding a package (i.e. kornia) and "ignored" for installation of dependencies (nvidia-cudnn-cu11) of the package to be installed (kornia).}
In any case, that didn't work either.
Running poetry source add nvidia https://pypi.ngc.nvidia.com didn't work - presumably because poetry source add was added to poetry v1.2 and was not part of v1.1.13.
I also tried poetry add --source nvidia https://pypi.ngc.nvidia.com but I got
PermissionError

I'm out of ideas and hoped someone might help.
