TBS machine learning software setup error. Do we really use the tensor flow virtual env or not?

Hi team,

I followed your instructions on your e manual to install tensorflow and keras on my ROS kinetic PC. However
e manual
TurtleBot3 49 Machine Learning tutorial 1

However, when I run import tensorflow as tf I get the following errors. I am setting up this course for my students. Could you please update your e manual and make it reliable? Thanks a lot.

ImportError: Something is wrong with the numpy installation. While importing we detected an older version of numpy in ['/home/mario/anaconda2/lib/python2.7/site-packages/numpy']. One method of fixing this is to repeatedly uninstall numpy until none is found, then reinstall this version.

The last question is :
Why is it that u created a virtual environment called tensorflow but never activated it? Does it mean that ur tensorflow is installed in the root/base environment? In this case whats the use of creating a virtual env?

This question is asked on your youtube tutorial as well not answered yet. Cheers

Hi team,
I spend the whole to to try run your instructions on your e manual to install tensorflow and keras on my ROS kinetic PC. It didn't work. Would you please consider update your instruction to make it work? Thanks a lot. Cheers.

Hi @stevensu1838
I'm sorry about the delayed response.
The TurtleBot3 machine learning package is being reviewed and will be updated soon for the latest software support.
Thank you.
