Just installed Cuda to get Tensorflow using my GPU. I followed the instructions on https://www.tensorflow.org/install/gpu and have run the Cuda tests on https://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/ (deviceQuery and bandwidthTest) which both were fine.

When I open up PyCharm and run the following code

import tensorflow as tf

print(tf.test.is_gpu_available(
    cuda_only=False,
    min_cuda_compute_capability=None
))

It evaluates to True but I get the following error messages appear:

What do these mean and should I be concerned?

(Running Windows 10, Python 3.6.8, Cuda Toolkit 10.0, Tensorflow 1.13.1)

These are not error messages, but informational messages. These are indicated by the I following date and time. These occur normally, and are no cause for concern. The different types of log levels can be found here.

    Ahhh - reading them, they didn't seem problematic but I'm something of a beginner and I'm used to anything appearing in red being something that need's addressing. Thanks!! – Charlie Apr 12 '19 at 16:23
