AndroidEnv quits because of an unexpected keyword argument 'use_poll'

[s-gv]

I tried running run_random_agent.py and got a crash right after the virtual device booted. What might be the problem? Does AndroidEnv need a newer version of Python than 3.6?

Hello @s-gv, yes, that's correct for now. Coincidentally, I am working on removing pexpect from AdbController, which should fix this bug. We just have some internal components that depend on that functionality, but I expect to work around the problems in a few weeks and then we'd be able to push a version that should work for your setup. In the meantime AndroidEnv does require a more up-to-date Python version.

Thanks @kenjitoyama. Updating pexpect to 4.8.0 seems to have fixed it even in Python 3.6.

[kenjitoyama]

@a-gergely, can we update pexpect in the meantime?

[kenjitoyama]

Sorry for the delay here. For a long time now we have removed pexpect as a dependency, so this bug is not valid anymore.
