Could anyone tell me what files I should download and which statements I must execute in the command line to install Matplotlib? I have Python 2.7.13 on Windows 10 64 bit. These are the files I unzipped: All downloaded from: http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy Commands I executed: python -m pip install -U pip setuptools python -m pip install matplotlib python -m pip install -U pip I am getting these two errors when checking if Numpy and Matplotlib are installed. >>> import numpy **Traceback (most recent call last): File "<pyshell#3>", line 1, in <module> import numpy File "numpy\__init__.py", line 142, in <module> from . import add_newdocs File "numpy\add_newdocs.py", line 13, in <module> from numpy.lib import add_newdoc File "numpy\lib\__init__.py", line 8, in <module> from .type_check import * File "numpy\lib\type_check.py", line 11, in <module> import numpy.core.numeric as _nx File "numpy\core\__init__.py", line 26, in <module> raise ImportError(msg) ImportError: Importing the multiarray numpy extension module failed.
