Hi when I run the example "" I get the following error with pymongo. Any idea on how to fix this?

Thanks in advance

Apologies, I forgot to specify a default of None for the pymongo argument. I've just committed a change, it should fix this.

[lcassano]

Thanks for the comment.
By the way you have another issue in qmix_central_no_hyper.py lines 46 and 47:
if self.args.central_skip:
y = y + agent_qs.sum(dim=-1, keepdim=True)

I got an error that self.args does not have attribute central_skip. I guess it is a similar issue. I just commented these two lines out and at least the algorithm seems to run properly.
Also what file is the one where intermediate results are saved (to plot curves)?

[tabzraz]

Thanks! I've removed that too (it was an option from early on in testing to have a skip connection in qCentral that wasn't used).

logging.py (https://github.com/oxwhirl/wqmix/blob/master/src/utils/logging.py) gathers the various things which are logged and then sacred saves them (to disk by default, sacred has other options for storing results like a mongodb).

[lcassano]

Sacred creates a .json file? In results several *.json files are saved, but none that have the evolution of "battle_won_mean" across iterations. I'm wondering if there's a bug or I should be looking somewhere else or there is a flag I must turn on.

One other question: If I run the code on the terminal everything seems to be ok. But if I try to run it on Pycharm "websocket.create_connection(url, timeout=timeout_seconds)" always times out. I know this is not a firewall issue, any thoughts on this?

[tabzraz]

Under the results/sacred/ there should be a directory for each run where sacred is saving stuff (config.json, cout.txt, info.json, run.json, etc).
info.json should have 2 fields for each of the logged entries, one for the value and one for the timestep that value was logged ("battle_won_mean" and "battle_won_mean_T" for example).

I usually run the code from PyCharm (using a venv) and haven't had problems with SC2 timing out.

[lcassano]

Thanks for the info. I'm using Pycharm (with a conda env) and it can never connect (same issue with Pymarl), it gives after around 110 attempts. I get:

...

I guess I'll keep looking. Thanks for the quick replies and if you think of something related to this issue please do tell :)

It's weird that it can start the SC2 instance but can't connect to it.

Are you able to start and connect to a jupyter notebook from within your pycharm (independent of PyMARL)?

[lcassano]

It's weird that it can start the SC2 instance but can't connect to it. -> Agreed XD

Are you able to start and connect to a jupyter notebook from within your pycharm (independent of PyMARL)? -> No idea, I never tried connecting to a jupyter notebook from within pycharm. I'll give it a shot, see what happens.

Hey by running install_sc2.sh all necessary components are installed? Or is it also necessary to install the free version of SCII from https://starcraft2.com/en-us/? I installed the free version and I'm starting to think this is the problem.
When you train an agent you get real time rendering of the games being played?

[tabzraz]

install_sc2.sh should install all the necessary SC2 files to run the experiments with. When I train an agent I don't get any graphical output on Linux.
I think you only need the free version of SC2 when you want to view a replay.
