Submissions Q&A

Over 1 year ago

@arthurj
The core issue is that if any agent is importing any large libraries (rainbow, tensorflow, dopamine, etc) before the agent can load the environment the test will never be started no matter how long the timeout_wait parameter is.

The easiest way would be to add a delay to the environment container starting up to give time for the agent to load, without referring to hacky methods such as deferring imports.

In local docker testing the agent container must always be ready before the environment container starts as well.

[Announcement][git error] Large Model Weights in your Submission Repository

Over 1 year ago

@mohanty @shivam ok after making my build fail I noticed the commands the server is running is not running the correct commands

https://gitlab.aicrowd.com/banjtheman/obstacle-tower-challenge/issues/9

Currently

git clone git@gitlab.aicrowd.com:USER/obstacle-tower-challenge.git
cd obstacle-tower-challenge
git checkout lfs

Which just makes a new detached branch and doesn’t pull down files
The server should use git lfs pull instead to pull down LFS files

git clone git@gitlab.aicrowd.com:USER/obstacle-tower-challenge.git
cd obstacle-tower-challenge
git lfs pull

this is a better and easier solution then the one I had before

@ChenKuanSun I found it easier to just delete the repo and start fresh and then use git lfs track before you add the file to the repo.

git init
git remote add YOUR_URL
git lfs install
git lfs track file
git add .
git commit -am “initial commit”
git tag -am “test” tag
git push -u origin master tag

@mohanty ok getting close created fresh repo with out the $store$ files and confirmed that the image runs the evaluation locally after some minor updates, but getting weird error on build server

DataLossError (see above for traceback): Checksum does not match: stored 3961381255 vs. calculated on the restored bytes 87951365

Evalutation error : Unity environment took too long to respond

Over 1 year ago

Was able to get around this by using the defer import strategy so the mlagent text came 1 second after startup, bit hacky but seems to be only way to get test to run.

@mohanty the git lfs files are being added to gitlab, but i don’t think the build server is pulling the lfs files.

getting this error

2019-03-13T14:16:44.691582001Z     raise OSError('Not a gzipped file (%r)' % magic)

When i clone repo with git clone, I also dont get lfs files

Evalutation error : Unity environment took too long to respond

Over 1 year ago

@mohanty yea, I’ve increased mine to 600 (even 30000 once) but all that does is keep the agent container idle, it looks like if the environment container starts before the agent displays

 INFO:mlagents_envs:Start training by pressing the Play button in the Unity Editor.

The test never starts, and this is easily reproducible on a local environment

The ~10 second startup time seems to be the issue as noted here Starter kit stuck "pending" state for a day

Is it possible to delay environment container say 60 seconds after agent container starts?

Is there a max repo size?

Over 1 year ago

Seeing similar issue, suspect its the same thing happens right when agent tries to load checkpoints

@shivam had similar issue as well and could use logs for guidance…
https://gitlab.aicrowd.com/banjtheman/obstacle-tower-challenge/issues/4

Also got another weird issue on a different submit

Great the image was able to build successfully now

Is there a max repo size?

Over 1 year ago

So my repo size is 4.4GB under the 10GB limit stated there, my code is in gitlab so the problem is not there.

The problem seems to be in the build process in the repo2docker phase. The script works fine on my local box, but there seems to be some file size issue on their build server. Would like some guidance on if there is away to remedy that issue.

Is there a max repo size?

Over 1 year ago

Hey, I was able to submit my build for evaluation, however my model weights are pretty large(4.4GBs) and it seems the build server is out of space? Here is the error I’m getting…

Step 27/33 : COPY src/ ${HOME}
failed to copy files: failed to copy directory: Error processing tar file(exit status 1): write /checkpoints/$store$_observation_ckpt.100.gz: no space left on device

Is there a max repo size or a recommend way to add large files to our docker image?
