tensorflow: <built-in function AppendInt32ArrayToTensorProto> returned NULL without setting an error

Question

Had various issues getting tensorflow onto my system and eventually did with v1.4.1. Trying to run this: https://github.com/sherjilozair/char-rnn-tensorflow

SystemError: built-in function AppendInt32ArrayToTensorProto returned NULL without setting an error

Searched and couldn't find this specific issue or any patches in newer versions with this same isusue.

You are using an older Tensorflow version , which is probably not compatible with your current python version .

1. check your computer configuration and install a matching Tensorflow version with the help of the following table: https://www.tensorflow.org/install/pip#package-location
2. Install a python version that matches your Tensorflow version (also can be found in the link provided above)
3. Check your python version: $ python3 --version
4. Check your Tensorflow version:$ pip3 list | grep tensorflow
5. If versions are matching as stated in the table above you'd probably get rid of the error

I've encountered a similar problem when I was trying to run the Tensorflow image retraining script: https://github.com/tensorflow/hub/raw/master/examples/image_retraining/retrain.py

In my case the problem was caused by Tensorflow 1.11.0 not being compatible with python 3.7.0.

Steps that solved the problem for me:

1. Uninstall python 3.7.0.
2. Install python 3.6.0.
3. I run the script again, and now it run properly

Hope it will hellp :)
