Hi, i have trained a TAO model and the output is an onnx model. I am trying to run inference using the TAO toolkit with the below command:

tao model lprnet inference -m /workspace/model.onnx -i /workspace/image.jpg -e /workspace/lpr_spec.txt -k nvidia_tlt

However, it prompt the below error:

INFO: Starting LPRNet Inference.
INFO: Merging specification from /workspace/tao_ws/lpr_spec.txt
Unsupported model type: .onnx
INFO: Inference was interrupted
Execution status: PASS

Any advice? May i know why it prompted unsupported model type. Thanks

Please refer to notebook tao_tutorials/notebooks/tao_launcher_starter_kit/lprnet/lprnet.ipynb at main · NVIDIA/tao_tutorials · GitHub or user guide.
The tao model lprnet inference runs against hdf5 file.

Can you guide me how to convert onnx to hdrf5 model format?

5

You can get the hdf5 file during training. Please find it.

6

Im so sorry, is there any ways that I could convert onnx to hdf5 because I think I have deleted the hdf5 before and I couldn’t get it back anymore.

7

No, we cannot convert onnx to hdf5.

Is this useful?

9

Suggest you to train again to get the hdf5 files.

10

Can you search result folder if there are .hdf5 files or .tlt files?
