Description

Hi, I followed your instructions to profile the following codes:

#This is the testing program to see whether the nvprof can work or not

import torch
import torch.cuda.profiler as profiler
from apex import pyprof
pyprof.nvtx.init()

torch.autograd.profiler.emit_nvtx()

total = 0

for i in range(100000):
    total = total + i

print(total)

I followed the instruction on the pyprof website (https://github.com/NVIDIA/apex/tree/master/apex/pyprof). The error came when I tried the last line of command:

python -m apex.pyprof.prof --csv net.dict > results.csv

The error message is shown below:

Traceback (most recent call last):
  File "/usr/lib/python3.5/runpy.py", line 184, in _run_module_as_main
    "__main__", mod_spec)
  File "/usr/lib/python3.5/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/home/yingj4/.local/lib/python3.5/site-packages/apex/pyprof/prof/__main__.py", line 10, in <module>
    main()
  File "/home/yingj4/.local/lib/python3.5/site-packages/apex/pyprof/prof/prof.py", line 182, in main
    kernel = eval(line)
  File "<string>", line 1
    no such table: CUPTI_ACTIVITY_KIND_CONCURRENT_KERNEL
          ^
SyntaxError: invalid syntax

It seems to have an incompatibility with the python file . May I ask how to fix this issue?
Also, the sql file is empty.
Thank you!

Research direction

Reproduce the reported command, python -m apex.pyprof.prof --csv net.dict > results.csv, using the profiling output described in the issue. Start with apex/pyprof/prof/__main__.py and apex/pyprof/prof/prof.py, especially the main() path that evaluates the kernel text. Done means the command handles the reported profiling input without the SyntaxError and produces the expected CSV output.
