Finding the cause of failure of Tensorflow calling GPU

Problem finding

Open the image, enter python, import tensorflow, and check the prompt information. A

warning appears here.cudart64_101.dll not found

Solution

Find the cuda directory you installed, enter the bin file and find the cudart64_*.dll file. Maybe your file is cudart64_102.dll, but you only need to change this file to the file name that is not found as shown above.

Finish

View available devices

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

At this time we can see our own GPU information, indicating that it has been successful.
