No such file or directory: 'julia'

[ShunliRen]

After my installing the julia package, the following error happened when I run the code 'gen_models'.
FileNotFoundError: [Errno 2] No such file or directory: 'julia'
WHY? thx!

You need to install Julia in order to generate the spectral embeddings.

If you're too lazy, you can just run the models without the spectral embeddings - I think MLP + C&S on Products still gets to 83.56 or so.

The problem is that after my installing julia, the error occur. I CAN import julia ,but the error happened. Even i don't use "use-embedding" , the error still occurs.
FileNotFoundError: [Errno 2] No such file or directory: 'julia'

Can you post the exact command you're running, as well as the stack trace?

python gen_models.py --dataset products --model mlp --hidden_channels 200

embeddings/spectralproducts.pt not found or not enough iterations! Regenerating it now

I do not use embedding.
and how to generate embedding?

[Chillee]

Ah - comment out line 148 and 147 here: https://github.com/CUAI/CorrectAndSmooth/blob/master/gen_models.py#L148 to run without embeddings.

To install Julia for generating the spectral embeddings, you need to install pyjulia in addition to the actual Julia language itself: https://julialang.org/

Similar problem here!
I installed Julia and made PATH all right, but it says
" julia.core.UnsupportedPythonError: It seems your Julia and PyJulia setup are not supported. "
Could you please tell me what version did you use? (Python, Pytorch, cuda, Julia, PyJulia)
Mine was (3.7.7, 1.8.0, 10.1, 1.5.4, ???)

3.8.3 ， 1.7.0，10.2，0.5.6. _

[q-hwang]

I am using python 3.6.10, pytorch 1.6.0, cuda 10.1, julia 1.0.5, pyjulia 0.5.6. Please check against the installation steps in https://pyjulia.readthedocs.io/en/latest/installation.html.

1. You need to run import julia; julia.install() in addition.
2. It seems that PyCharm run configuration may cause the error. Directly run in shell seems fine.

Hi, I also have a question about Julia

' from julia import Main ' no Main
