convert.py doesn't work with RTX

[antongisli]

I get an error very similar to the memory issues seen on the detect scripts, but trying to set the TF2 options for gpu memory usage doesn't help/work in convert.py (I tried to import tf2 there and set the options the same as others have done in the other scripts but no dice).

converting and getting the checkpoints on another machine (AWS instance) and copying them over let's me proceed with using the detect scripts, but would be nice to be able to run the conversion locally.

Windows 10, RTX2080.

Hey, Anton!
I've seen your post here: opencv/opencv#14827.
Did you solve the problem?

[antongisli]

Hi, No, I didn't look into it more. I started to look at the TF2 based yolo implementation instead. Cheers, Anton

@antongisli Do you happen to have a link to this? Id really like to take a look at.

TF2 based yolo implementation

[zzh8829]

have you tried the latest tensorflow 2.1 version, unfortunately i can't test it for you since i don't have RTX2080

Convert.py worked for me with Ubuntu 18.04 and an RTX2080, if that helps.

Add these lines to models.py right after the imports

gpus = tf.config.experimental.list_physical_devices('GPU')
if gpus:
try:
# Currently, memory growth needs to be the same across GPUs
for gpu in gpus:
tf.config.experimental.set_memory_growth(gpu, True)
logical_gpus = tf.config.experimental.list_logical_devices('GPU')
print(len(gpus), "Physical GPUs,", len(logical_gpus), "Logical GPUs")
except RuntimeError as e:
# Memory growth must be set before GPUs have been initialized
print(e)

Thanks MrPerdition.

Your code snippet from TF site (https://www.tensorflow.org/guide/gpu#limiting_gpu_memory_growth) manage to solve the issue and weights are converted. Here's my succesful output if anyone is interested.
(note: despite the CUDA out of memory error, weights are still converted)

I have the same problem if you could solve it please help me as well :(
