Hi,

There are several ways to check the installed module version.

The best approach is to confirm using the python runtime, which will load pymongo based on your current environment variables.

It's also useful to check that PyMongo has the C extensions installed as these improve serialisation performance over the pure Python implementation:

$ python -c "import pymongo; print(pymongo.version); print(pymongo.has_c())"
3.0.2
True

Alternatively you can check what version pip thinks is installed. The caveat is that different module versions might be loaded based on Python environment variables or with tools like virtualenv.

$ pip list | grep pymongo
pymongo (3.0.2)

Regards,
Stephen

Thanks Stephen,

The pymongo.has_c() returned False, would that be a big issue or can be ignored?  I am going to use this library to RobotFramework and already got some issue(Python 2.7.3).

Though the pure python BSON library shipped in PyMongo 3 is much faster in many ways than what ships in PyMongo 2, you will still get better performance with the C extensions installed. See the installation docs here for rereqs if you are on a Linux machine:

For Windows or OSX there are precompiled binary packages on pypi:
