On my Macbook Pro, I use Anaconda Navigator 1.8.2. for Python2 when I installed it.
I use I've used this link, successfully install a python3.6 Kernel into jupyter notebook. :https://ipython.readthedocs.io/en/latest/install/kernel_install.html
I try the same procedure, by changing python3 to python3.5 (3.6.4 and 3.5.4 respectively if you call which python3 or python3.5 on my mac). Note that the python 3.5 is just downloaded and installed few hours ago from: https://www.python.org/downloads/release/python-354/ and I chose: Mac OS X 64-bit/32-bit installer, to complete the installation
Then I do the following as instructed by Ipython Document: run python3.5 -m pip install ipykernel
in terminal
But error goes:
Collecting ipykernel

You are using pip version 9.0.1, however version 9.0.3 is available. You should consider upgrading via the 'pip install --upgrade pip' command.
Then I try to upgrade the pip by running this code in terminal: python3.5 -m pip install --upgrade pip
But there is still error: Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:719) - skipping Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages
You are using pip version 9.0.1, however version 9.0.3 is available. You should consider upgrading via the 'pip install --upgrade pip' command.
It looks like it's the python3.5's problem, but right now I have no idea what's going on under the hood. If you know how to solve it, please share with me. Thank you
