inference_openvino.py: data type false #5

Closed feichai2004 closed 4 years ago

feichai2004 commented 5 years ago

I tried to run "python inference_openvino.py ", setting the datapath to dataset.json folder and model input to FP32 folder. I see the following error and no output result is produced. The error is produced by line 67: "validation_generator = DataGenerator(False, args.data_path, **validation_data_params)"

/usr/lib/python3.5/site-packages/h5py/init.py:34: FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated. In future, it will be treated as np.float64 == np.dtype(float).type. from ._conv import register_converters as _register_converters Using TensorFlow backend.

I've updated the code to correct this. The only issue I still have is that I haven't had time to confirm the OV output for 3D.

I noticed that the output dice score is very low. The train set's dice score is 0.85.

Yes. I've got someone looking in that. Hope to provide the fix soon.

I think I've finally fixed the issue. The OpenVINO model assumes the input dimensions to be batch, channels, depth, height, width. The Keras/TF model assumes batch, height, width, depth, channels. Can you let me know if the new code works for you?
