Question

如何检查我使用的是哪个版本的 NumPy？

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

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 5

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

import numpy
numpy.show_config()

Answer 6

我们可以使用pip freeze来获取任何 Python 包版本，而无需打开 Python shell。

pip freeze | grep 'numpy'

Answer 7

You can try this:

pip show numpy

Answer 8

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 9

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 10

For Python 3.X print syntax:

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

Or

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

Answer 11

import numpy
print numpy.__version__

Answer 12

In a Python shell:

>>> help()
help> numpy

Answer 13

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

Answer 14

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.

Answer 15

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 16

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 .

Answer 17

For Windows

pip list | FINDSTR numpy

For Linux

pip list | grep numpy
