I wrote a package to do this, once the package pkgman is installed:

• Check if a package is installed and able to be imported, if not, install it and then import:

  from pkgman import include
  include("numpy")
  

• Check if many packages installed and able to be imported, if not, install them and then import:

  from pkgman import include
  include(["numpy", "pandas"])
  

To me, this wrapper is super helpful when I need to do data analysis, in which, requirements are constantly changing & always need to install and then import new ones.

To start using this module, just pip install pkgman. Opensourced at https://github.com/reycn/pkgman
