I would like to use the Keras Tensorflow package for R in RStudio.

Everytime I use the command install_keras() or install_tensorflow(), I get the following error:

Collecting keras 
Could not fetch URL https://pypi.python.org/simple/keras/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
Could not find a version that satisfies the requirement keras (from versions: )
No matching distribution found for keras

I discovered that every time I tried to install Keras within R, it created a virtualenv in the following directory (basically overwriting it):

/users/username/.virtualenvs/

Where it has Python version Python 2.7.10 (default, Jul 14 2015, 19:46:27). When I directly activate the virtualenv and try pip install keras, I receive the same error. I figured out on Stack Exchange that I could solve this issue by using pip install requests[security]. This seemed to fix the problem but nevertheless, R won't use it.

How can I fix this problem, realising that every time I use install_keras(), I overwrite the virtualenv and the same problem occurs? I even tried using the tensorflow URL directly, but I get the same error when it tries to install other important packages.

Important information:

• MacOS: 10.10.5
• R: 3.3.3

I'm new to this, so my apologies if I don't use the terminology correctly. I did manage to make Tensorflow Keras work in Anaconda and using Jupyter, but I can't seem to make it work in R in that environment as well.
