Unable to produce the result for dmlab30 language environment

[Shengyu-Feng]

Hi, I tried to run the shallow IMPA,LA model on dmlab30 language model, but besides language_select_described_object, both language_select_located_object and language_execute_random_task are stuck in the 0 reward. I'm not sure if there's any hyper parameters needed to tune or more frames are needed to train.

I only changes the larger model to the shallow model in the source code. Number of actors is 48, batch size is 32, all other parameters follow the default value.
