Unable to access Tensorboard on AWS EC2 Instance

Question

I am using a p2xlarge AWS EC2 Instance for training Tensorflow Models. Training an Evaluation works perfectly fine, but when i try to access / run Tensorboard is face the following error:

RuntimeError: module compiled against API version 0xc but this version of numpy is 0xa

locale.Error: unsupported locale setting

I am using the anaconda tensorflow_p27 environment and to make my project run i had to install PIL and to be able to do this numpy was downgraded. the numpy error is always shown but normally does not influence tensorflow in any negative way.

Has somebody seen this error before / knows how to solve it?

Answer 1

This error is related with the locale configuration of the instance (which probably is not set.

Setting that with the following commands should solve the problem:

export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales
