Thanks a lot for the contribution, however, I am not able to merge this PR before you update the changelog.md. Could you put your Github and PR IDs in to the changelog.md?

Many thanks.

Thank you very much for considering my pull request. I have updated the changelog.md with my GitHub ID and PR

Hello,

The error seen in both:

• ci/cirlceci: test_sources_py2_cpu and
• ci/cirlceci: test_sources_py2_cpu

is:

ERROR: No matching distribution found for scikit-learn==0.21.0 (from tensorlayer==2.0.0)

I do not believe my doc change resulted in this error.

MORE INFO: On the scikit web pageScikit-learn from 0.21 requires Python 3.5 or greater, but the tests that are failing are being run with Python 2.7 so perhaps a configuration file needs to be modified to use a different version of scikit-learn when using Python2.7.

I don't want to further edit anything in an attempt to address an ERROR, but am just reporting what I am seeing...
