I recommend you comment out PYTHONPATH in your .bashrc file (or wherever
it's defined) and create a new one with only 1 entry, namely

   export PYTHONPATH=/home/mike/gnuradio/lib/python2.7/dist-packages

But check it - see if that is correct directory by

   cd /home/mike/gnuradio/lib/python2.7/dist-packages

There should be at least 3 sub directories.

Check to see if there's anything in the lib64 directory

   cd /home/mike/gnuradio/lib64/python2.7/dist-packages

If it exists and has the same sub directories as the lib path then you
have 2 gnuradio installations - you have choose one or the other.

Look at the dates and take the directory with the most recent date.

Once you've set the PYTHONPATH, set

   export LD_LIBRARY_PATH=/home/mike/gnuradio/lib

or

   export LD_LIBRARY_PATH=/home/mike/gnuradio/lib64

- which ever the case may be - although it's not clear you need to set
LD_LIBRARY_PATH - but it won't hurt if it's done correctly.

It's either the lib path or the lib64 path - but not both.

Then start python, type type

  from gnuradio import gr

If that works try gnuradio-companion
