AttributeError: module 'signal' has no attribute 'SIGALRM'

[echeg]

On Windows, signal() can only be called with SIGABRT, SIGFPE, SIGILL, SIGINT, SIGSEGV, or SIGTERM. A ValueError will be raised in any other case.

C:\Repos\UnityRF\ml-agents\python\unityagents\environment.py in __init__(self, file_name, worker_id, base_port)
     86                     str(file_name)))
     87 
---> 88         old_handler = signal.signal(signal.SIGALRM, timeout_handler)
     89         signal.alarm(30)  # trigger alarm in x seconds
     90         try:

AttributeError: module 'signal' has no attribute 'SIGALRM'

This is a duplicate of #5.

A easy workaround is removing the lines 10, 88, 89, 99 and 100 from /python/unityagents/environment.py. That's not a nice solution but at least it is working this way.

Thanks for pointing this out. We just pushed a fix to check for socket timeout in a way that is more cross-os compatible: #9. Please let me know if things work for you now.

Also closing since it is a duplicate of #5
