When I run 'python tests/atari_init_test.py', it shows below:

====================================================================== ERROR: test_atari_init (main.AtariInitTest) Tests that a DQN agent is initialized.

I used virtualenv, and using that I am able to run it fine.

OK

[amirkhango]

@tosandip I am using conda env but failed. I will try virtualenv as you said

[iteachmachines]

Ok try it.If it doesn't work i will try with some other alternatives.

[inoryy]

Works fine for me with conda. Review installation instructions carefully, I think you might be missing absl-py, for example.

[psc-g]

if this is still failing, would you mind providing the commands you ran to install, as well as the command you use to run the test? if it's passing, we can close this. :)

[tengkz]

@amirkhango ,I ran into the same problem, how can you fix it?

[tengkz]

@psc-g I solved it by add this line in the setUp function in atari_init_test.py: FLAGS(["--gin_files dopamine/agents/dqn/configs/dqn.gin",]) It seems the existing line FLAGS.gin_files=xxx doesn't work for me, maybe some bug with my absl package, version=0.5.

[vladbph]

This worked for me: ` def setUp(self):

FLAGS( [ '--gin_files' ] )
FLAGS.gin_files = [ 'dopamine/agents/dqn/configs/dqn.gin' ]

FLAGS.base_dir = os.path.join(
    '/tmp/dopamine_tests',
    datetime.datetime.utcnow().strftime('run_%Y_%m_%d_%H_%M_%S'))
FLAGS.agent_name = 'dqn'
# `num_iterations` set to zero to prevent runner execution.
FLAGS.gin_bindings = [
    'Runner.num_iterations=0',
    'WrappedReplayBuffer.replay_capacity = 100'  # To prevent OOM.
]
FLAGS.alsologtostderr = True

`

[vladbph]

• Add FLAGS( ['--base_dir'] ) to all other tests in setUp()
