PS C:\yk_repo\yk_coding\pycallgraph2> python Python 3.10.11 (tags/v3.10.11:7d4cc5a, Apr 5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

import torch

=====the pytorch is fine！！！！！

then I run:

from pycallgraph2 import PyCallGraph from pycallgraph2.output import GraphvizOutput

with PyCallGraph(output=GraphvizOutput()): #code to profile import torch ''' tested with pytorch 2.0.0 and 1.13.1 PS C:\yk_repo\yk_coding\pycallgraph2> python .\demo_pcg2.py C:\Python310\lib\site-packages\torch\distributed\distributed_c10d.py:283: UserWarning: torch.distributed.reduce_op is deprecated, please use torch.distributed.ReduceOp instead warnings.warn( Traceback (most recent call last): File "C:\yk_repo\yk_coding\pycallgraph2\demo_pcg2.py", line 6, in import torch File "C:\Python310\lib\site-packages\torch_init_.py", line 1187, in from .functional import * # noqa: F403 File "C:\Python310\lib\site-packages\torch\functional.py", line 8, in import torch.nn.functional as F File "C:\Python310\lib\site-packages\torch\nn_init_.py", line 1, in from .modules import * # noqa: F403 File "C:\Python310\lib\site-packages\torch\nn\modules_init_.py", line 2, in from .linear import Identity, Linear, Bilinear, LazyLinear File "C:\Python310\lib\site-packages\torch\nn\modules\linear.py", line 7, in from .. import functional as F File "C:\Python310\lib\site-packages\torch\nn\functional.py", line 1437, in VF.threshold, File "C:\Python310\lib\site-packages\torch_VF.py", line 26, in getattr def getattr(self, attr): File "C:\Python310\lib\site-packages\pycallgraph2\tracer.py", line 25, in tracer self.processor.process(frame, event, self.memory()) File "C:\Python310\lib\site-packages\pycallgraph2\tracer.py", line 171, in process module_path = module.file File "C:\Python310\lib\site-packages\torch_VF.py", line 27, in getattr return getattr(self.vf, attr) AttributeError: 'torch._C._VariableFunctionsClass' object has no attribute 'file' '''

Same issue on Windows 11 with Python 3.9.19 using:

• pycallgraph2==1.1.3
• torch==2.1.0
• torchaudio==2.1.0
