Issue 1

Input:

nvidia-docker exec -i -t pylot /home/erdos/workspace/pylot/scripts/run_simulator.sh

Output:

Error: No such container: pylot

Issue 2

Input (after installing everything):

python run_random_search.py 30

Output:

Commit 7dc89bcc50698a46c940622ac547e29067024d65 addresses the above issues.

Please let me know if there are other issues to be addressed. Thanks!

on the updated version, when I executed pylot using the following commands (line by line):

nvidia-docker exec -i -t pylot /bin/bash
cd workspace/pylot/
python3 pylot.py --flagfile=configs/detection.conf

I got the following error:

Traceback (most recent call last):
  File "<string>", line 31, in <module>
  File "/home/erdos/workspace/pylot/pylot/perception/detection/detection_operator.py", line 89, in __init__
    with open(self._flags.mlco_list_path, 'rb') as f:
TypeError: expected str, bytes or os.PathLike object, not NoneType
ERROR: CARLA version 784d9b9f is not supported; assuming this is version 0.9.10

but it does not halt. It's still running without printing any new lines for around 10 mins. I am unsure if this is the correct behaviour.

FYI, on the terminal where I executed the docker image, I have the following messages:

I think I'll remove the sanity check steps. I remembered, after seeing the above error, that the pylot source code is changed to a degree that the usual pylot obstacle detection might not work easily.

Regarding the terminal output, it seems that you GPU is not recognized. I'll update the INSTALL.md further to fix it.

Commit b8bf685a970af3437222fc42f9413642c6178dd5 has the necessary updates: removed sanity check. Added a way to monitor gpu and search execution.

Please let me know if there are other problems. Thanks.

Okay, it turned out that the error ALSA lib confmisc.c:767:(parse_card) cannot find card '0' is about the sound card. Anyway, it seems fine now. Thanks.
