How do I check which version of NumPy I'm using?
PythonNumpyVersionPython Problem Overview
How can I check which version of NumPy I'm using?
Python Solutions
Solution 1 - Python
import numpy
numpy.version.version
Solution 2 - Python
>> import numpy
>> print numpy.__version__
Solution 3 - Python
From the command line, you can simply issue:
python -c "import numpy; print(numpy.version.version)"
Or:
python -c "import numpy; print(numpy.__version__)"
Solution 4 - Python
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)
....
Solution 5 - Python
You can also check if your version is using MKL with:
import numpy
numpy.show_config()
Solution 6 - Python
We can use pip freeze to get any Python package version without opening the Python shell.
pip freeze | grep 'numpy'
Solution 7 - Python
You can try this:
> pip show numpy
Solution 8 - Python
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)

Solution 9 - Python
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
Solution 10 - Python
For Python 3.X print syntax:
python -c "import numpy; print (numpy.version.version)"
Or
python -c "import numpy; print(numpy.__version__)"
Solution 11 - Python
import numpy
print numpy.__version__
Solution 12 - Python
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
Solution 13 - Python
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.
Solution 14 - Python
In a Python shell:
>>> help()
help> numpy
Solution 15 - Python
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)
Solution 16 - Python
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.
Solution 17 - Python
For Windows
pip list | FINDSTR numpy
For Linux
pip list | grep numpy
