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

My Environment

Ubunutu 18

tensorflow 1.15.0/1.14.0

My Question

I have reviewed similar issues for example TensorFlow : failed call to cuInit: CUDA_ERROR_NO_DEVICE

The key difference is I do not have the tensorflow-gpu package installed. How can this error be raised by normal TensorFlow?

Answer 1

You can attempt to work around this problem on cpu-only machines by using the tensorflow-cpu package instead of tensorflow.

pip uninstall tensorflow
pip install tensorflow-cpu

Answer 2

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.
