Can I use conda instead pip to install the packages?
I see in your documents that you use the pip to install the python packages. I use the Conda Python 3.6. According the conda document one should use conda instead of pip to install the packages.
If a package isn't in the Anaconda repository you need to either create the package with conda build or go ahead and use pip. See https://www.anaconda.com/blog/using-pip-in-a-conda-environment.
