Install error on Windows

[menasrac]

Hello,

I couldn't install exojax on Windows with the pip command or by cloning the code from the GitHub page.
It seems there is a conflict with jaxlib version > 0.4

Here is the complete error message
ERROR: Cannot install exojax and numpyro==0.11.0 because these package versions have conflicting dependencies.

The conflict is caused by:
numpyro 0.11.0 depends on jaxlib>=0.4
numpyro 0.12.1 depends on jaxlib>=0.4.7
numpyro 0.12.0 depends on jaxlib>=0.4
numpyro 0.10.1 depends on jaxlib>=0.1.65
numpyro 0.10.0 depends on jaxlib>=0.1.65

numpyro 0.2.3 depends on jaxlib==0.1.36
numpyro 0.2.2 depends on jaxlib==0.1.36
numpyro 0.2.1 depends on jaxlib==0.1.32
numpyro 0.2.0 depends on jaxlib==0.1.27
numpyro 0.1.0 depends on jaxlib>=0.1.14

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

However, the installation worked on wsl using the pip command.

Thank you for your help

Hello,
I got exactly the same error when running on Windows pip install exojax

[HajimeKawahara]

Hello! Thanks for the report!
I do not use Windows python except for WSL. What is the exact environment? Anaconda windows?
@minouHub @menasrac

[menasrac]

Yes I use anaconda on windows

[minouHub]

Hello,
Yes it's on Anaconda Windows for me as well. I even tried with a fresh conda environment:

conda create -n test_env conda
conda activate test_env
pip install exojax

and got

Thanks. I will try to figure out the reason but I found something problematic on pip jax installation on Windows:

These pip installations do not work with Windows, and may fail silently;

in https://github.com/google/jax#installation

[minouHub]

alright, so it's a jax problem. Maybe you could add a little note concerning Windows environments in the installation section of the master page
