How to detect if numpy is installed

I think you also may use this

>> import numpy
>> print numpy.__version__

Update: for python3 use print(numpy.__version__)

The traditional method for checking for packages in Python is "it's better to beg forgiveness than ask permission", or rather, "it's better to catch an exception than test a condition."

try:
    import numpy
    HAS_NUMPY = True
except ImportError:
    HAS_NUMPY = False

In the numpy README.txt file, it says

After installation, tests can be run with:

python -c 'import numpy; numpy.test()'

This should be a sufficient test for proper installation.

You can try importing them and then handle the ImportError if the module doesn't exist.

try:
    import numpy
except ImportError:
    print "numpy is not installed"
