How do I check which version of NumPy I'm using?

Question

How can I check which version of NumPy I\'m using?

(FYI this question has been edited because both the question and answer are not platform specific.)

Answer 1

Run:

pip list

Should generate a list of packages. Scroll through to numpy.

...
nbpresent (3.0.2)
networkx (1.11)
nltk (3.2.2)
nose (1.3.7)
notebook (5.0.0)
numba (0.32.0+0.g139e4c6.dirty)
numexpr (2.6.2)
numpy (1.11.3) <--
numpydoc (0.6.0)
odo (0.5.0)
openpyxl (2.4.1)
pandas (0.20.1)
pandocfilters (1.4.1)
....

Answer 2

You can also check if your version is using MKL with:

import numpy
numpy.show_config()

Answer 3

We can use pip freeze to get any Python package version without opening the Python shell.

pip freeze | grep 'numpy'

Answer 4

If you're using NumPy from the Anaconda distribution, then you can just do:

$ conda list | grep numpy
numpy     1.11.3     py35_0

This gives the Python version as well.

If you want something fancy, then use numexpr

It gives lot of information as you can see below:

In [692]: import numexpr

In [693]: numexpr.print_versions()
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Numexpr version:   2.6.2
NumPy version:     1.13.3
Python version:    3.6.3 |Anaconda custom (64-bit)|
                   (default, Oct 13 2017, 12:02:49)
[GCC 7.2.0]
Platform:          linux-x86_64
AMD/Intel CPU?     True
VML available?     False
Number of threads used by default: 8 (out of 48 detected cores)

Answer 5

You can try this:

pip show numpy

Answer 6

Just a slight solution change for checking the version of numpy with Python,

import numpy as np 
print("Numpy Version:",np.__version__)

Or,

import numpy as np
print("Numpy Version:",np.version.version)

My projects in PyCharm are currently running version

1.17.4
