Error when verifying tensorflow installed correctly

Question

After installing tensorflow via this guide - https://github.com/jeffheaton/t81_558_deep_learning/blob/master/t81_558_class_01_1_overview.ipynb - I get an error that I do not understand. I can get into and then I active tf and get a prompt.

After install, I run the following code to verify installation:

import sys

    import tensorflow.keras
    import pandas as pd
    import sklearn as sk
    import tensorflow as tf

    print(f"Tensor Flow Version: {tf.__version__}")
    print(f"Keras Version: {tensorflow.keras.__version__}")
    print()
    print(f"Python {sys.version}")
    print(f"Pandas {pd.__version__}")
    print(f"Scikit-Learn {sk.__version__}")
    print("GPU is", "available" if tf.test.is_gpu_available() else "NOT AVAILABLE")

This is the error I get:

These are the packages I installed:

pip install --exists-action i --upgrade sklearn
pip install --exists-action i --upgrade pandas
pip install --exists-action i --upgrade pandas-datareader
pip install --exists-action i --upgrade matplotlib
pip install --exists-action i --upgrade pillow
pip install --exists-action i --upgrade tqdm
pip install --exists-action i --upgrade requests
pip install --exists-action i --upgrade h5py
pip install --exists-action i --upgrade pyyaml
pip install --exists-action i --upgrade tensorflow_hub
pip install --exists-action i --upgrade bayesian-optimization
pip install --exists-action i --upgrade spacy
pip install --exists-action i --upgrade gensim
pip install --exists-action i --upgrade flask
pip install --exists-action i --upgrade boto3
pip install --exists-action i --upgrade gym
pip install --exists-action i --upgrade tensorflow==2.0.0-beta1
pip install --exists-action i --upgrade keras-rl2 --user

As a noob, I have tried to google the error, but every installation that I have come across with errors is not similar to mine.

The installation is via Juypter on a 3.6 kernel. All the packages installed correctly, but for some reason, verifying the install produces an error.

edit: Sorry, I forgot to include the code!

Answer 1

My current installation was a mess. I installed a couple of ide's, then python. The path was messed up, and it was a royal pain to troubleshoot.

I started with a fresh os install and I am doing it the right way.

Answer 2

Installing tensorflow can be a pain, especially if you need GPU support. Luckily it's gotten easier recently, and it is much easier than that guide makes it seem.

This one line should install the correct version of tensorflow-gpu, keras, and the appropriate cuda and cudnn toolkits:

conda install -c anaconda keras-gpu

I would just give it a go if you haven't already as it should just take a few minutes

Answer 3

Too much of a headache getting tf installed on my laptop.

Solution: AWS EC2 Ubuntu 18.04 (free tier), installed Tensorflow, doing remote development with VS Code locally.

I learned a ton setting up tf on Linux.
