This is not the public API, numpy.__version__ is.

mmorris Over a year ago

Actually import numpy ; numpy.version.version . The lack of import numpy through me, an obvious newbie.

dawg Over a year ago

Since the use of __version__ in recommended in PEP8 and most packages support __version__ vs the non standard version.version I think that this answer should be treated more as a curiosity than an accepted method. Use numpy.__version__ or <package>.__version__ as Dominic Rodger's answer recommends Parse the version (and create your own version strings) as recommended in PEP 386 / PEP 440.

Henry Schreiner Over a year ago

Actually, in NumPy 1.20, numpy.version.version is typed, and numpy.__version__ is not (could be an oversight).

This is the API we numpy developers will support. numpy.version.version is an implementation detail that should not be relied upon.

well, this works for most well-written python packages.

This is the PEP8 Way(tm) +1

David Over a year ago

for Python 3 and the standard numpy import name use print(np.__version__)

From the command line, you can simply issue:

python -c "import numpy; print(numpy.version.version)"

Or:

python -c "import numpy; print(numpy.__version__)"

This is actually very nice as it allows you to check the version of numpy even if you have two different versions running on two different versions of python. py -2 -c "import numpy; print(numpy.version.version)" py -3 -c "import numpy; print(numpy.version.version)"

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)
....

Or pip freeze if in a virtual environment?

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

import numpy
numpy.show_config()

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

pip freeze | grep 'numpy'

That only works if you installed numpy via pip, not via brew or apt-get, for example.

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)

Simply

pip show numpy

and for pip3

pip3 show numpy

Works on both windows and linux. Should work on mac too if you are using pip.

You can get numpy version using Terminal or a Python code.

In a Terminal (bash) using Ubuntu:

pip list | grep numpy

In python 3.6.7, this code shows the numpy version:

import numpy
print (numpy.version.version)

If you insert this code in the file shownumpy.py, you can compile it:

python shownumpy.py

or

python3 shownumpy.py

I've got this output:

1.16.1

Just a slight caution that it's possible that you may have python and python 3 both installed with numpy. Then when doing the pip list | grep numpy method it will show one of the two (typically the python 3's numpy version). When you run the shownumpy.py program on both python and python 3, they will show you exactly what version is on each respective python environment.

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

For Python 3.X print syntax:

python -c "import numpy; print (numpy.version.version)"

Or

python -c "import numpy; print(numpy.__version__)"

Exact duplicate of the answer of @meduz . For python 3, it is print(numpy.__version__), not print numpy.__version__

Pure Python line that can be executed from the terminal (both 2.X and 3.X versions):

python -c "import numpy; print(numpy.version.version)"

If you are already inside Python, then:

import numpy
print(numpy.version.version)

It is good to know the version of numpy you run, but strictly speaking if you just need to have specific version on your system you can write like this:

pip install numpy==1.14.3 and this will install the version you need and uninstall other versions of numpy.
