OSError: could not get source code when running LineProfiler

[Wei Yuan]

Hi, when I trying to use the LineProfiler example, the following error message pops up:

import torch

from pytorch_memlab import LineProfiler

def inner():
... torch.nn.Linear(100, 100).cuda()
...
def outer():
... linear = torch.nn.Linear(100, 100).cuda()
... linear2 = torch.nn.Linear(100, 100).cuda()
... inner()
...
with LineProfiler(outer, inner) as prof:
... outer()
...
Traceback (most recent call last):
File "", line 1, in

File "/home/wyuancs/miniconda3/envs/response-selection/lib/python3.8/inspect.py", line 798, in findsource
raise OSError('could not get source code')
OSError: could not get source code

How could I solve this problem? I tried to search online, but not find any solution

Can you try copy-paste these lines into a python source file and then runs it.

Do you execute these codes in python xxx.py, python terminal, or ipython terminal ?

Hi, Thanks for your reply. I'm using python xxx.py
