Question

im using the below packages but somehow im getting the below error:

import numpy
import tflearn
import tensorflow
import random

Error:

Answer 1

The main error occurs due to missing module tensorflow.contrib . I believe tflearn may have that as a dependency. Newer versions of tensorflow (>2.0) does not include contrib module.

You may be able to resolve the issue by upgrading tflearn to the latest version. As per their docs TF2.0 is supported now. ( Installation instructions here )

Other than that you have a warning (W) and information (I) provided by tensorflow .

1. Warning states that it is not able to access cuda files for GPU support.
2. Information says you can ignore the warning if you are not using GPU.

Do you wish to use tensorflow with GPU support? This may require installation of cuda and other dependencies.
