How to run in windows.

[sjanapro]

nougat is not recognised in the cmd after installing..

[lukas-blecher]

It should be. How did you install it? Make sure you activate the environment before calling nougat.

[sjanapro]

Using pip and I am not using any environment.

[sjanapro]

There is no virtual environment. I just installed the package and it's dependencies then tried to run it from cmd but it is showing the error as I mentioned earlier.

[lukas-blecher]

show me some logs. did the installation work? without problems?

I didn't manage to make nougat work either (on windows 11). When installing with pip everything went ok. Maybe it's just a stupid mistake on my part. I found a nougat.exe file inside some python folder and ran it here using a powershell console getting the message below

@gelprec sorry, that is a bug for python 3.9. It's fixed in main but I didn't push to pypi yet

[gelprec]

Thanks. I uninstalled python 3.9 and installed the newer version 3.11.5. I reinstalled nougat and it works, but the default CPU version is very slow (about 3 minutes for two pages pdf), hence it's necessary to install a gpu/cuda aware torch version. I followed these steps

• Uninstall the previous torch version (pip uninstall torch)
• Go to https://pytorch.org/get-started/locally/ where is a command generator and see there that the recommended/default cuda version is CUDA 11.7.
• I go to the https://developer.nvidia.com/cuda-toolkit-archive and choose here that older version 11.7 and install it (it's a big package, almost 3 giga)
• Execute finally the command suggested/generated at https://pytorch.org/get-started/locally/

Now the process is much speedier and the resulted ocr seems very accurate, better than I expected.

I am still getting this on python 3.11

you should better use docker

RUN apt-get update
RUN mkdir workspace
