Hello guys.

I am trying to install icefall on Windows.

I was able to run following installation

pip install torch==1.13.0+cu116 torchaudio==0.13.0+cu116 -f https://download.pytorch.org/whl/torch_stable.html

But I got a problem with following installation

pip install k2==1.24.3.dev20230725+cuda11.6.torch1.13.0 -f https://k2-fsa.github.io/k2/cuda.html

Same commands on Linux are working fine.

Could you help please.

What am I doing wrong?

we don't provide cuda-enabled wheels for windows. Please install k2 form source with cuda support on windows.

Guys, I have troubles with installation of GCC on windows. There are some ways to install it. But it seems that it is installed in some dedicated terminal and I cannot see it installed in terminal of windows. Any help is appreciated.

[csukuangfj]

please install msvc via visual studio 2022.

[AlexandderGorodetski]

Thank you so much.
I have a question regarding installation of cuda and cudnn.
I have nvidia-smi installed on my windows. It means that gpu drivers were installed. Maybe it is enough?

but nvcc is not available on my computer. So I guess that I have to install cuda and cudnn. Guys , in your tutorial you have great explanation about how cuda and cudnn should be installed on Linux , but
I do not see there explanation about installing cuda and cudnn on windows. I found that I can install cuda and cudnn on windows using Nvidia site but I am not sure about it. What is yours recommendation please?

Sorry that we don't have experience about installing cudatoolkit and cudnn on windows.

I suggest that you search with google for that.

Guys, is there someone in the forum that was able to install K2 under Windows?

[mc-marcocheng]

These are some python package installation basics:

1. Install msvc.
2. Install miniconda.
3. Create a python environment with miniconda: conda create -n env python=3.10 -y; conda activate env
4. conda install cudatoolkit cudnn -c conda-forge -y
5. Install PyTorch with version that matches the CUDA version installed on your system
6. pip install git+https://github.com/k2-fsa/k2

Hello @mc-marcocheng , is that crucial to use miniconda or using of Anaconda is OK too ?
