Gprof2Dot can't parse my prof file :/

[portnov]

I have a .prof file, which is generated by python 3.9.2 which is built into Blender 2.93.1.
Now I try to parse it with my system's python 3.9.2:

[portnov]$ python3 ./gprof2dot.py /tmp/test.prof                                                          master [9:58]
Traceback (most recent call last):
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 3555, in <module>
    main()
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 3509, in main
    profile = parser.parse()
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 1322, in parse
    self.parse_cg()
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 1304, in parse_cg
    while not self._cg_header_re.match(self.readline()):
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 1142, in readline
    line = self.fp.readline()
  File "/usr/lib/python3.9/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfb in position 0: invalid start byte

I also tried with Blender's python, just in case the problem is in python's compilation options:

[portnov]$ ~/soft/blender-2.93.1-linux-x64/2.93/python/bin/python3.9 ./gprof2dot.py /tmp/test.prof       master [10:01]
Traceback (most recent call last):

    main()
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 3509, in main
    profile = parser.parse()
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 1322, in parse
    self.parse_cg()
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 1304, in parse_cg
    while not self._cg_header_re.match(self.readline()):
  File "/home/portnov/src/gprof2dot/./gprof2dot.py", line 1142, in readline
    line = self.fp.readline()
  File "/home/portnov/soft/blender-2.93.1-linux-x64/2.93/python/lib/python3.9/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfb in position 0: invalid start byte

No luck either :/

Attaching prof file:
test.zip

Also note: https://github.com/baverman/flameprof tool parses the same file successfully.

Please refer to the documentation about Python profilers on https://github.com/jrfonseca/gprof2dot#python-profile .

Note in particular the -f pstats option. Without -f option gprof2dot believes the input is gprof format.

Thanks, -f pstats worked!
