Error Initializing WandbLogger on Windows

[bhatiaabhinav]

I have Julia 1.6.2 installed on Windows 11. I am using Miniconda for PyCall.

I am getting the following error on invoking WandbLogger constructor.

julia> using Wandb
[ Info: Using Wandb version 0.12.1

julia> lg = WandbLogger(project = "Wandb.jl", name = nothing)
wandb: Currently logged in as: abhinavbhatia (use `wandb login --relogin` to force relogin)
ERROR: unknown option `-c`

At that point, the interpreter freezes. Everything runs fine on Ubuntu though.

Figured that wandb.init() is causing the problem when trying to create the wandb process. On Windows, adding the argument settings=wandb.Settings(start_method="thread") to the wand.init() call solves the problem.

To pass that argument via WandbLogger constructor, one would need to do:

using PyCall
@pyimport wandb
lg = WandbLogger(project = "Wandb.jl", name = nothing,  settings=wandb.Settings(start_method="thread"))

@avik-pal The problem is happening again. You undid the fix?

[avik-pal]

This is happening even with explicitly passing the settings kwarg? (I don't have a Windows machine to test)

@bhatiaabhinav can you try https://github.com/avik-pal/Wandb.jl/pull/5?

[bhatiaabhinav]

I didn't check with explicit kwarg. But I thought you had already made it by default to spawn wandb as a new thread instead of a new process. Maybe I misunderstood.

So if you recommend that we should pass the kwarg explicitly (when on Windows), it would be helpful if you document it in the Readme.

[bhatiaabhinav]

try #5 how?

[bhatiaabhinav]

Ah you want me to test that new branch. Ok let me try.

@avik-pal Yeah it works fine. The pull request looks good to go!
