question about run code in training on one gpu #5

Hello, when I enter code with "python tools/train.py configs/swin/upernet_swin_tiny_patch4_window7_512x512_160k_ade20k.py --options model.pretrained=models/upernet_swin_tiny_patch4_window7_512x512.pth [model.backbone.use_checkpoint=True]" on my windows,it happened: (RTX3090) D:\Swin-Transformer-Semantic-Segmentation>python tools/train.py configs/swin/upernet_swin_tiny_patch4_window7_512x512_160k_ade20k.py --options model.pretrained=models/upernet_swin_tiny_patch4_window7_512x512.pth [model.backbone.use_checkpoint=True] .\work_dirs\upernet_swin_tiny_patch4_window7_512x512_160k_ade20k Traceback (most recent call last): File "D:\Anaconda\envs\RTX3090\lib\site-packages\yapf\yapflib\pytree_utils.py", line 115, in ParseCodeToTree tree = parser_driver.parse_string(code, debug=False) File "D:\Anaconda\envs\RTX3090\lib\lib2to3\pgen2\driver.py", line 104, in parse_string return self.parse_tokens(tokens, debug) File "D:\Anaconda\envs\RTX3090\lib\lib2to3\pgen2\driver.py", line 72, in parse_tokens if p.addtoken(type, value, (prefix, start)): File "D:\Anaconda\envs\RTX3090\lib\lib2to3\pgen2\parse.py", line 159, in addtoken raise ParseError("bad input", type, value, context) lib2to3.pgen2.parse.ParseError: bad input: type=3, value="'model'", context=('\n', (4, 0))

so I want ask the run code example for windows when I train on one gpu?

Hi, @wuliwan

Which version of python do you use? By google searching ib2to3.pgen2.parse.ParseError: bad input: type=3, value="'model'", context=('\n', (4, 0)), I found that this error may be caused by lower version of python (see this issue).

You could try with python 3.7 or 3.8.

I got the same error.

It is not because of Python version.

In my case, the error comes from the config file.

Reason In config file, everything should be a dictionary, ONLY dictionary, but I wrote some codes to define classes, codes to do this do that, then those lines of codes caused that error.

Solution: Keep only lines that define the model structure.

Can you tell me how to modify the code？ thank you very much
