error: Pip package install meet RequestsDependencyWarningfirst when update by:

!pip install --quiet lucid==0.2.3

the warning is relavent to  old crypto:

 

~/isic/local/lib/python2.7/site-packages/pip/_vendor/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.

  warnings.warn(warning, RequestsDependencyWarning)

therefore update:

sudo pip install --upgrade cryptography

the version is upgraded, But something broken, cause:

$pip list

AttributeError: 'module' object has no attribute 'SSL_ST_INIT'

Resolved this by resintalling PyOpenSSL() and pip will automatically upgrade:

sudo python -m easy_install --upgrade pyOpenSSL

 

pip --version

pip 18.1 from ~/isic/local/lib/python2.7/site-packages/pip (python 2.7)
