- Pip version: pip 9.0.1
- Python version: Python 3.5.2 and Python 2.7.10 installed
- Operating system: OSX - 10.13.4
Description:
I've tried to install Keras (keras.io) and faced with a problem related confirming ssl certificate.
What I've run:
First:
$ pip install keras
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:645) - skipping
Could not find a version that satisfies the requirement keras (from versions: )
No matching distribution found for keras
Then I checked my system:
$ python -c "import ssl; print ssl.OPENSSL_VERSION"
LibreSSL 2.2.7
$ python --version
Python 2.7.10
$ python3 -c "import ssl; print (ssl.OPENSSL_VERSION)"
OpenSSL 0.9.8zh 14 Jan 2016
$ python3 --version
Python 3.5.2
$ pip --version
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (python 3.5)
Actually it seems quite odd when I run pip, it automatically goes with Python3 but my defauly python is Python2. Can there be such conflict?
Also, I've tried upgrading pip:
$ pip install --upgrade pip
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:645) - skipping
Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages
$ pip --version
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages (python 3.5)
Again SSL certificate error occurred.

@jackton1 thank you.
Also I tried upgrading pip2 by
curl https://bootstrap.pypa.io/get-pip.py | pythonbut it didn't work.However I solved the pip2 issue by:
pip2 install --upgrade pipimzeali commentedon Apr 17, 2018

This is due to the recent TLS support deprecation by Python.org sites. Need to upgrade
pip(but without usingpip!) See this SO post with detailsevilsperm commentedon Apr 29, 2018

Worked perfectly, I'm not getting the ssl error anymore and can finally install again.
