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

>> import numpy
>> print numpy.__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__)"

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'

For Python 3.X print syntax:

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

Or

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

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)

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) <--

odo (0.5.0)

import numpy
print numpy.__version__

In a Python shell:

>>> help()
help> numpy

You can try this:

pip show numpy

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.

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 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

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.

For Windows

pip list | FINDSTR numpy

For Linux

pip list | grep numpy
