🐛 Bug

Crash when running nle-ttyplay (or nle-ttyplay2) on the ttyrec3 file generated by the test function in agent.

OSError: Illegal header (1679347987, 464255, 4, 2)

To Reproduce

Steps to reproduce the behavior:

  1. Run the example agent training (python -m nle.agent.agent --num_actors 5 --batch_size 32 --unroll_length 80 --learning_rate 0.0001 --entropy_cost 0.0001 --use_lstm --total_steps 1000000000)
  2. Run test mode python -m nle.agent.agent --mode test --use_lstm --save_ttyrec_every 1
  3. Run ttyplay on generated ttyrec3 file, in my case this is something like nle-ttyplay nle_data/20230320-213238_4evrptzm/nle.256.1.ttyrec3.bz2

Expected behavior

Expected to see a ttyplay replay.
