Error Messages:

failed call to cuInit: CUDA_ERROR_NO_Device: no CUDA capable device is detected
this is also what I encountered when running a CNN SVM classifier program of tensorflow GPU today. It’s not the problem of the program. It’s our graphics card.

Solution:

import tensorflow as tf

config = tf.compat.v1.ConfigProto()
config.gpu_options.allow_growth = True
session = tf.compat.v1.InteractiveSession(config=config)

Just add these lines of code to the head of the code, and you don’t need to write this code belowos.environ['CUDA_VISIBLE_DEVICES'] = '/gpu:0'
