Can you provide the actual saved profiler data? The output of the
command itself doesn't provide enough information to diagnose the
problem, since it doesn't have full file paths etc.
When you do (thanks Gökhan for the less verbose version):
python.exe -c "import cProfile; cProfile.run('import pylab', 'test.out')"
this should produce a binary file "test.out" that can be loaded with the
pstats module and used by GUI tools such as KCacheGrind to help us get
to the bottom of this.
