Bug

Hi,
I trained the model yolov5m on google colab with a custom dataset labeled person only, and then saved the ckpt to local. I want to load ckpt to apply to the tracking problem, with the command:
import torch
from ultralytics import YOLO
model = torch.hub.load('ultralytics/yolov5', 'custom', 'trained_v5_30ep.pt')
Then the error: ImportError: cannot import name 'TryExcept' from 'utils' (unknown location)
Hope you can help me soon. Thanks a lot

@ngocnd2402 hello! Thank you for reaching out to us. We apologize for the inconvenience. This error occurs because the TryExcept module is not present in the utils module of YOLOv5.

There are a few things you can try to resolve this:

1. Make sure you are using the latest version of YOLOv5.

2. Double-check that you have correctly installed all dependencies, including PyTorch and TorchVision.

3. Try importing TryExcept from the parent directory of the utils module, like this:

from ..utils.general import TryExcept

We hope this helps. Please let us know if you have any other questions or concerns. Thank you for your interest in YOLOv5!

This is how i corrected mine goto yolov5/utils/general.py and modify like this in the import statements

import sys
sys.path.append('/home/gus/yoloscratch/yolov5/')
from ultralytics.yolo.utils.checks import check_requirements

For me, that error was occuring when using predict.py for yolov5 classification in the form of ImportError: cannot import name 'TryExcept' from 'utils' ('path to init.py' (which is inside site_packages/utils, in my conda environment)). Also this py file was empty.
After trying this command : python -c "import utils; print(utils.file)", it seems that it wants to load init.py from my utils module inside yolov5 folder. So I just erased this init.py file from my conda environment, and it seems to work now for predicting.

@ljubanradisin hi there,

I apologize for the inconvenience you experienced with the ImportError: cannot import name 'TryExcept' from 'utils' error while using the predict.py script for YOLOv5 classification.

Thank you for providing the details of your solution. It seems that removing the __init__.py file from the utils folder in your conda environment resolved the issue for you.

We appreciate your contribution and sharing your workaround. If you have any further questions or concerns, please don't hesitate to let us know.

Thank you for your support of YOLOv5!

I solved the issue by uninstalling the utils package with pip uninstall utils.
