upgrade pytohn2 to python3 and TF working with GPU

[SothanaV]

• python2 to python3
• edit detect Car yolo -> yolo2
• train LPR cpu with GPU

Future

• yolo2 to yolo3 because yolo3 fasterthan yolo2
• maybe blocking to thread,subprocess.queue or async

Hello Sothana,

Thanks for these commits,

I tried to use these files and getting the following error when I run following command: bash run.sh -i samples/test -o /tmp/output -c /tmp/output/results.csv:

Keras - 2.2.4
TF - 2.1.0

Could you please let me know how to resolve the error.

Thanks in Advance,

Hi,

I tried using the following to over come the issue, Could you please confirm whether this solution is recommended?

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()
