Hi there,

I am getting the following error when I try to run this part. Any thoughts?

fastai::install_fastai(gpu = FALSE, cuda_version = '10', overwrite = FALSE)

r-miniconda/envs/r-reticulate/python.exe" -m pip install --upgrade "torch==1.8.0+cpu torchvision==0.9.0+cpu torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html" "IPython" "pydicom" "kornia" "opencv-python" "scikit-image" "timm" "fastinference[interp]" ERROR: Invalid requirement: 'torch==1.8.0+cpu torchvision==0.9.0+cpu torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html'

Thank you very much for your time.

Kind regards,

M

Hi, AFAIR the issue is related to reticulate. Please, do the following and try to reinstall fastai.

require(devtools)
install_version("reticulate", version = "1.21", repos = "http://cran.us.r-project.org")

Great, it worked... I thought it could not find the specified torch versions.

The new CRAN version does not require reticulate downgrade. Thanks
