问题
I ran a python code and I got the error just, "Segmentation fault". I then ran "gdb python" and re-run the code from the (gdb) prompt, and I got the following result:
#0 0x00007fffed573487 in fprank_ ()

Can anyone help me sort out my mistake? Thanks!
回答1:
From the traceback one can interpret that it is scipy native libraries which are crashing in fprank_() function.
It is most likely a scipy bug. Contact scipy community and/or file a bug against scipy with an isolated test case.
It is unlikely you will find a solution in stackoverflow.com, because it is clearly a crashing bug.
