code error when running the test code

1st error :..pysc2/lib/features.py:737: FutureWarning: arrays to stack must be passed as a "sequence" type such as list or tuple. Support for non-sequence iterables such as generators is deprecated as of NumPy 1.16 and will raise an error in the future.

which PySC2 version do you have?

[simayuhe]

PySC2 version is 2.0.2. and the examples at https://github.com/deepmind/pysc2 can be run correctly.

I can confirm the first one, though it's actually a FutureWarning, not an error (e.g. doesn't prevent the code from running). Unfortunately, it's happening inside PySC2, so I can't really do much about it.

While not a good idea in general, but as a temporary workaround, you can suppress these warnings inside your code, like so:

import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)

I'm unable to replicate the second error, even in a clean environment install. For reference, here is packages dump from the env:

# Name                    Version
python                    3.6.7

I just found this happening to me when incorrectly using Pysc2 2.0.1.
This post helped me debug. and finally get this running after switching from mac to PC.
Thanks for the amazing tool @inoryy . Truly incredible

@EvanWilliams thank you for the kind words! I'm happy to hear you've found reaver useful :)
