'''

|
build profile graph for the given instance
|
||
|
|
|
||
|
|
running:
|
||
|
|
$ get_gprof <args> <instance>
|
||
|
|
|
||
|
|
executes:
|
||
|
|
gprof2dot -f pstats <args> <type>.prof | dot -Tpng -o <type>.call.png
|
||
|
|
|
||
|
|
where:
|
||
|
|
<args> are arguments for gprof2dot, such as "-n 5 -e 5"
|
||
|
|
<instance> is code to create the instance to profile
|
||
|
|
<type> is the class of the instance (i.e. type(instance))
|
||
|
|
|
||
|
|
For example:
|
||
|
|
$ get_gprof -n 5 -e 1 "import numpy; numpy.array([1,2])"
|
||
|
|
|
||
|
|
will create 'ndarray.call.png' with the profile graph for numpy.array([1,2]),
|
||
|
|
where '-n 5' eliminates nodes below 5% threshold, similarly '-e 1' eliminates
|
||
|
|
edges below 1% threshold
|
||
|
