How to get the progress of the execution

[rtmlp]

Hi,

I am using numba on a method which has lot of independent for loops with in a loop. How to find the progress of the execution i.e to see until which point has the code been executed. I used to use python print method but since that is not available in nopython=True mode, is there any other way to monitor the progress of the code

Thanks

While this is probably more appropriate for the mailing list than the issue tracker, I just wanted to note that you can use the print() function in nopython mode (http://numba.pydata.org/numba-doc/latest/reference/pysupported.html#built-in-functions). If you are using python2, you need to add from __future__ import print_function to the top of your file, and then you can use print -- for example:

@nb.jit(nopython=True)
def func(N):
    for i in range(N):
        print('loop #: ', i)

Thanks @synapticarbors . I tried to use print method but using f-strings in python. I used the original method and it works fine now. So I am closing this thread. Thanks for the help.

As a general note, #3166 will move Numba toward support for temporarily leaving nopython mode to run a block of arbitrary Python code. This will allow a wider range of callback options, like calling progress bar libraries or notebook widget updates.
