From the command line, you can simply issue:

从命令行,您可以简单地发出:

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

Or:

要么:

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

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

您还可以检查您的版本是否使用MKL:

import numpy
numpy.show_config()

Run:

跑:

pip list

Should generate a list of packages. Scroll through to numpy.

应该生成一个包列表。滚动到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)

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

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'

You can try this:

你可以试试这个:

pip show numpy

pip show numpy

If you're using NumPy from the Anaconda distribution, then you can just do:

如果您正在使用Anaconda发行版中的NumPy,那么您可以这样做:

$ conda list | grep numpy
numpy     1.11.3     py35_0

This gives the Python version as well.

这也给出了Python版本。


If you want something fancy, then use numexpr

It gives lot of information as you can see below:

它提供了大量信息,如下所示:

In [692]: import numexpr

In [693]: numexpr.print_versions()
