I install mxnet from This link and test with resnet18 working but when I try to :
from mxnet import image

And then look Image got issue like this :
The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File “train.py”, line 120, in
for i, (data, label) in enumerate(train_data):
File “/usr/local/lib/python3.6/dist-packages/mxnet/gluon/data/dataloader.py”, line 484, in next
batch = pickle.loads(ret.get(self._timeout))

File “/home/nvidia/mxnet/mxnet/src/io/image_io.cc”, line 250
MXNetError: Build with USE_OPENCV=1 for image io.

I try build mxnet from source success too.
cmake
-DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE}

This is my cmake config.

Hi,

The error complains about the OpenCV support in MXNet.

We have verified a working script with OpenCV enabled in the below comment.
Please give it a try:

Thanks.
