Cannot start tensorboard from console due to numpy issue - numpy

Question

I'd like to make use of TensorBoard.I already saved training and validation data in the same directory as the rest of the project data using the tensorflow.keras.callbacks library.
I already pip reinstalled numpy, didn't work out. Then I deleted tb-nightly and tensorboard as I had them both for some reason and just pip reinstalled tb-nightly.
(Tensorflow) C:\Users\alias>python -c "print(__import__('numpy').__version__)"
1.16.2
(Tensorflow) C:\Users\alias>python -c "print(__import__('tensorflow').__version__)"
2.0.0-alpha0
(Tensorflow) C:\Users\alias>python -c "print(__import__('tensorboard.version').version.VERSION)"
1.14.0a20190301
When calling it via Anaconda prompt on a Win10-OS , the following happens:
(Tensorflow) C:\Users\alias>tensorboard --logdir=logs\

Would be glad about some help.
Thanks in advance!

Answer 1

Did you do a fresh install and or update recently?
Not sure if this applies to your case or not? Yesterday I installed the latest conda, for python 2.7, from scratch and updated to the latest packages after installation. Running python from pycharm or windows powershell and importing numpy would throw a multiarray import error. The fix for me was to downgrade numpy from ?1.16.12? to ?1.5.14?. Sorry, but I am away from my PC's were I encountered the error but I think those versions are correct.

Answer 2

I experienced the same error in my local Jupyter notebook. Upgrading Numpy package worked for me.
Try upgrading Numpy as below
pip install numpy==1.16
If the above doesn't work, upgrade tensorflow with below command and try again
pip install tensorflow --upgrade

The issue was solved # Github https://github.com/tensorflow/tensorboard/issues/2092
