Quickstart notebbok: Run Multi-Agent DDPG System.

[jbakams]

I was playing around with the quickstart notebook but having this error on Run Multi-Agent DDPG System (I tried locally and on colab):

UnparsedFlagAccessError: Trying to access flag --lp_termination_notice_secs before flags were parsed.

Hi @jbakambana, thanks for pointing this out. This was related to an issue with an external library that we use for scaling google-deepmind/launchpad#14 .

We have a PR out for this fix (#291). I will let you know when to test this again.

Hi @jbakambana, the PR for the fix has been merged. The notebook should work again now 😄

Please let us know if there are still any issues. Thanks again for pointing this out!

Hi @arnupretorius , thanks for your feedback. The notebook is working now on colab. But the problem remains when I tried with Desktop even though I reinstalled Mava.

@jbakambana Try printing out your version of launchpad like, pip show dm-launchpad-nightly.

It should be 0.3.0.dev20210730. It it isn't, it means the re-install failed for some reason. Please confirm that you have the latest setup.py when you re-installed Mava?

[jbakams]

I got this: Version: 0.3.0.dev20210809. How do I check for the setup.py file?

.

[KaleabTessera]

@jbakambana If you are on the develop branch, please do a pull from master (git pull). That should pull an updated setup.py file. Then after that, re-installing Mava should work.

[jbakams]

Thank you @KaleabTessera it's ok now!

[KaleabTessera]

My recent PR retroduced this, I am fixing this to work with latest LP.

Looks fixed.
