CommError: Run initialization has timed out after 60.0 sec

When I am using wandb, the error is:

CommError: Run initialization has timed out after 60.0 sec.
Please refer to the documentation for additional information: Frequently Asked Questions About Experiments

And when I scan my output, I found that:

16:57:37.579 [warn] StdErr from Kernel Process wandb: Network error (SSLError), entering retry loop.
16:58:34.665 [warn] Cancel all remaining cells due to cancellation or failure in execution

I have checked my time and tried to use different network, but it still exist.

I have tried this:

but seems not useful. Also, because I am using windows, “fork” is not available.

Hi @durablefrank158, thanks for reporting this! Could you please send debug.log and debug-internal.log for this run? These files are under your local folder wandb/run-<date>_<time>-<run-id>/logs in the same directory where you’re running your code. I will have a look at those files to see why this is crashing.

Also, could you provide the code snippet that is causing this? Thanks!

run = wandb.init(settings=wandb.Settings(start_method=“spawn”),
sync_tensorboard=True, # auto-upload sb3’s tensorboard metrics
monitor_gym=True, # auto-upload the videos of agents playing the game
save_code=False, # optional
if run_name is not None: = run_name

all_elems = [‘empty’, ‘sand’, ‘water’, ‘wall’, ‘plant’, ‘stone’, ‘lava’]
elems = all_elems[:num_elems]

policy_kwargs = dict(
features_extractor_kwargs=dict(features_dim=20, wm=wm_name, wm_layer=wm_layer, env=env),

checkpoint_callback = TensorboardCallback(elems, num_tasks, num_lines, num_circles, num_squares, env)
wandb_callback = WandbCallback(model_save_freq=10000, model_save_path=f"models/{}", verbose=2)
callback = CallbackList([checkpoint_callback, wandb_callback])

(Attachment debug-internal.log is missing)

the .log files are not authorized, how can I send them to you?
