It looks like the previous localtunnel call failed to create a localtunnel leading to an empty list. Can you try rerunning the notebook.

Thanks for the answer @tancik. I rerun the notebook but it does not work, same error. It seems it is related to node modules.

@akristoffersen Have you seen this issue?

I encountered a similar error. I think the problem is related to the IP address. I resolved it by restarting my router to change my IP address and the issue was solved.

I got the same error on the colab notebook, did you manage to solve it? I tried restarting the notebook, changing port and using ngrok instead of localtunnel but none of these worked.

EDIT: I solved by using: get_ipython().system_raw('lt -h "http://serverless.social" -p 7007 >> url.txt 2>&1 &') instead of : get_ipython().system_raw('lt --port 7007 >> url.txt 2>&1 &'). But the viewer don't visualize the training data now, maybe it can solved by changing manually the websocket_url variable. I found the solution here, it could be that when this happen it means that localtunnel is down.
