error: creating server: INTERNAL - failed to load all models

Description A clear and concise description of what the bug is.

I just run a simple demo. The model is downloaded by tensorflow.keras.applications.resnet50 and saved with model.save('./resnet50', save_format='tf').

structure:

                                                                                (tf)

Triton Information What version of Triton are you using? nvcr.io/nvidia/tensorrtserver:19.10-py3

To Reproduce Steps to reproduce the behavior.

nvidia-docker run --rm --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 -p8000:8000 -p8001:8001 -p8002:8002 -v /home/me/models:/models nvcr.io/nvidia/tensorrtserver:19.10-py3 trtserver --model-repository=/models

I’m sure the GPU driver is compatible with this docker. I can run another TensorFlow model successfully.

Describe the models (framework, inputs, outputs), ideally include the model configuration file (if using an ensemble include the model configuration file for that as well).

Expected behavior A clear and concise description of what you expected to happen.

Sorry, I cannot find any useful error messages.

[kemingy]

that’s correct, all models in the dirs will be checked when trtserver started. There is an option --exit-on-error=false may help.

I agree all the models in the dirs should be checked. But maybe it should skip the dirs named started with a dot? For example, .git/, .vscode/.

[kemingy]

sorry, using your zip file, i cannot reproduce your results on 20.02, 19.09 , 19.10 trtserver images. everything seems ok and says “successfully loaded ‘resnet50’ version 1”.

I moved it to a clean directory and it works. Is it because of the old folder contains several non-model directories? This doesn’t make sense.

Then I try to git init. After that, it failed to load the models.
