tensorflow (not tensorflow-gpu): failed call to cuInit: UNKNOWN ERROR (303)

Question

My Test

import tensorflow as tf
hello = tf.constant(\'Hello, TensorFlow!\')
sess = tf.Session()

My Error

Answer 1

Installing nvidia-modprobe can solve this issue.

sudo apt install nvidia-modprobe

Other solutions you can try are :

• Uninstall and install CUDA and cuDNN.
• Install tensorflow-gpu.
• Uninstall and install different Nvidia driver versions.

The problem also could be that only some /dev/nvidia* files are present before running Python with sudo, check using $ ls /dev/nvidia*, after running the Device Node verification script the /dev/nvidia-uvm file gets added.
