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

import numpy
numpy.version.version

Answer 2

>> import numpy
>> print numpy.__version__

Answer 3

From the command line, you can simply issue:

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

Or:

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

Answer 4

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

import numpy
numpy.show_config()

Answer 5

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 6

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

pip freeze | grep 'numpy'

Answer 7

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 8

You can try this:

pip show numpy

Answer 9

For Python 3.X print syntax:

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

Or

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

Answer 10

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

Answer 11

import numpy
print numpy.__version__

Answer 12

In a Python shell:

>>> help()
help> numpy

Answer 13

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)

Answer 14

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.
