Trouble with running PySC2

[EmpereurCC]

Hey I created an env on conda to test reaver and when i tried the command to try Beacon I had the logger issue. I followed your hotfix but I end up having weird errors depending on the agent I specify (A2C/PPO). For PPO for instance I get this error :

Traceback (most recent call last): File "C:\ProgramData\Anaconda3\envs\tf\lib\multiprocessing\process.py", line 258, in _bootstrap self.run() File "C:\ProgramData\Anaconda3\envs\tf\lib\multiprocessing\process.py", line 93, in run self._target(*self._args, **self._kwargs) File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\base\msg_multiproc.py", line 48, in _run obs = self._env.reset() File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\sc2.py", line 73, in reset obs, reward, done = self.obs_wrapper(self._env.reset()) File "C:\ProgramData\Anaconda3\envs\tf\lib\multiprocessing\process.py", line 258, in _bootstrap self.run() File "C:\ProgramData\Anaconda3\envs\tf\lib\multiprocessing\process.py", line 258, in _bootstrap self.run() File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\sc2.py", line 130, in __call__ obs['feature_screen'][self.feature_masks['screen']], File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\pysc2\lib\named_array.py", line 145, in __getitem__ index = _get_index(obj, index) File "C:\ProgramData\Anaconda3\envs\tf\lib\multiprocessing\process.py", line 93, in run self._target(*self._args, **self._kwargs) File "C:\ProgramData\Anaconda3\envs\tf\lib\multiprocessing\process.py", line 93, in run self._target(*self._args, **self._kwargs) File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\pysc2\lib\named_array.py", line 207, in _get_index "Can't index by type: %s; only int, string or slice" % type(index)) File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\base\msg_multiproc.py", line 48, in _run obs = self._env.reset() File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\base\msg_multiproc.py", line 48, in _run obs = self._env.reset() TypeError: Can't index by type: <class 'list'>; only int, string or slice File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\sc2.py", line 73, in reset obs, reward, done = self.obs_wrapper(self._env.reset()) File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\sc2.py", line 73, in reset obs, reward, done = self.obs_wrapper(self._env.reset()) File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\sc2.py", line 130, in __call__ obs['feature_screen'][self.feature_masks['screen']], File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\reaver\envs\sc2.py", line 130, in __call__ obs['feature_screen'][self.feature_masks['screen']], File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\pysc2\lib\named_array.py", line 145, in __getitem__ index = _get_index(obj, index) File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\pysc2\lib\named_array.py", line 145, in __getitem__ index = _get_index(obj, index) File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\pysc2\lib\named_array.py", line 207, in _get_index "Can't index by type: %s; only int, string or slice" % type(index)) File "C:\ProgramData\Anaconda3\envs\tf\lib\site-packages\pysc2\lib\named_array.py", line 207, in _get_index "Can't index by type: %s; only int, string or slice" % type(index)) TypeError: Can't index by type: <class 'list'>; only int, string or slice TypeError: Can't index by type: <class 'list'>; only int, string or slice

I love your work anyway and looking forward a fix thanks

Hello, I don't think this issue is related to logger. Have you followed Windows installation instructions?

[EmpereurCC]

Hello, thanks for the swift reply. I think I did follow the windows instructions but maybe something went wrong. 4 windows of SC2 open and nothing happends and I get this message.

Can you verify you've installed PySC2 from source? If yes, what command specifically do you use to run?

[EmpereurCC]

I think I did install it from source : pip install https://github.com/deepmind/pysc2/archive/master.zip

I make my run through this : import reaver as rvr

env = rvr.envs.SC2Env(map_name='MoveToBeacon') agent = rvr.agents.A2C(env.obs_spec(), env.act_spec(), rvr.models.build_fully_conv, rvr.models.SC2MultiPolicy, n_envs=4) agent.logger = rvr.utils.Logger() agent.run(env)

Hmm, I still think the issue is due to PySC2 version mismatch. Could you install it once more with forced upgrade? E.g. run

pip install --upgrade https://github.com/deepmind/pysc2/archive/master.zip

---

btw I've added a default logger, run pip install reaver again to fetch the newer version

Issue was resolved by re-installing in a clean conda env

Problem solved! Thanks a lot!
