Hello!im completely new to cntk .i recently installed cntk 2.7 (GPU version)on my pc (windows 10) with GeForce 940MX GPU. im trying to set up cntk and the faster rcnn object-detection example provided in the link below https://docs.microsoft.com/en-us/cognitive-toolkit/object-detection-using-faster-r-cnn ..im trying to run the toy example...

after running the install_data_and_model.py in Examples/Image/Detection/FastRCNN folder, i run the run_faster_rcnn.py Examples/Image/Detection/FasterRCNN folder i get the following error: Selected GPU[0] GeForce 940MX as the process wide default device.

Can someone help me with what the issue is all about?

This error always happen when you shutdown cntk when last model was saving,so the model file break
