Issue in installation

Hi,

I am trying to install this package, but I run into the following error after cloning and running setup.py

How did you install PyTorch?

And what is the output of

conda list
python3 -m torch.utils.collect_env

[jrplatin]

I am using a Docker image, but I'm using PyTorch 1.12 for CUDA 11.3 (same version as my install).

I listed the results of the two calls here:

What is the output of

find $CONDA_PREFIX -name "libmkl*"
find $CONDA_PREFIX -name "libmkl_core*"

[jrplatin]

I got this:

Thanks for your help so far! output.txt

[csukuangfj]

Well, you only have

/opt/conda/envs/ptca/lib/libmkl_core.so.2

but it is looking for /usr/bin/ld: cannot find -lmkl_core, i.e., libmkl_core.so.

Since you are using conda, I suggest that you use conda install to install PyTorch, which will also install mkl for you.

Got it thanks!

Quick update: I just had to run sudo apt-get install intel-mkl and it worked!
