UnicodeDecodeError, during test in drive_TestT1_Town01 #19

Closed jonfranc closed 4 years ago

jonfranc commented 5 years ago

Hello,

I receive a runtime UnicodeDecodeError, during test in drive_TestT1_Town01.

I am using Ubuntu 18.04 with carla:0.8.2 docker, and I executed the following run command:

python3 coiltraine.py --folder sample --gpus 0 -de TestT1_Town01 -vd CoILVal1 --docker carlasim/carla:0.8.2

After finishing train and validation, the process displays the "Iterating" in test for quite some time:

        STATUS:  Iterating

After some time, the error is produced and the following traceback is displayed:

Please advise!

Figured it out. The method merge_with_yaml() ({repo}/configs/coil_global.py:102) is erroneously attempting to read the swap file {repo}/configs/.*.yaml.swp, since I had my configuration file open in vim, on the Linux commandline, while initiating the training process.
