Bug

I am working with Yolov5 and i want to use the run function inside a custom python script.
I imported every modules and the entire run function.
I pass the main argument such as weights, source, imgsz as normal variables, but when it runs, the function stopped into the experimental.py script when it has to transform the model into FP32 model.
But if i run the application using os.system('.....'), i pass to this function:
ckpt = (ckpt.get('ema') or ckpt['model']).to(device).float() # FP32 model
the same kpt['model'].
Can someone help me?

Environment

-YOLO: Yolov5
-Conda version: 23.1.0
-Python version: 3.10.9

@Benti98, it sounds like the issue may have to do with the way the function is being called in your custom Python script. One issue could be that you're not passing the correct data types for weights, source, and imgsz. These variables should match the exact data types that the run function expects. Another issue could be related to the directory path. Double-check that the weights file path (if using one) is correct and accessible from your custom script. I hope this helps! If the issue persists, could you please provide more details or share your script so we can reproduce the error?

[ghost]

It doesn't give me any error, simply it exits the program saying anything.
I initialize the weights and the source like this:
weights = Path('yolov5/yolov5s.pt')
source = Path('static/files/webcamDetected.jpg')
and then i call the function like this:
run(weights=weights, source=source)
but inside the function experimental.py, in the line:
ckpt = torch.load(attempt_download(w), map_location='cpu') # load
ckpt = (ckpt.get('ema') or ckpt['model']).to(device).float() # FP32 model
the model is loaded correctly (it seems), but the script can't pass over the .float() line.

[glenn-jocher]

@Benti98, it sounds like the issue could be related to the device or precision. You might try adding a few debug print statements to the experimental.py script to see which line fails to execute. Additionally, make sure that the device mode in both cases (when called through os.system and when called directly) is the same.

One thing to try is to remove the .to(device) part in the line you mention, and see if it resolves the issue. If it does, then the issue might be related to the device you're using, as some devices might not be compatible with float32, especially if they are older or less powerful. In this case, try changing the device or using a lower precision.

If, after these steps, you're still having trouble, please let me know and I'll help you work through the issue.

[ghost]

The device is always the same, 'cpu', but even if i delete the .to(device) in the statement
ckpt = (ckpt.get('ema') or ckpt['model']).float() # FP32 model
the code can't go over it.
I use two print(), one before and one after this sentence and the script continues to print me only the first one, exiting next the program saying any error.
This is the checkpoint it is getting:

@Benti98 the detailed information you provided is helpful for debugging. The model structure seems to be loading correctly, so the issue might stem from the specific configuration or environment.

As a next step, try testing the model loading and conversion in a standalone script with minimal dependencies to isolate the issue. This will help pinpoint what might be causing the hang during the conversion to FP32.

If the issue persists, consider posting your detailed findings in our discussion forum at https://github.com/ultralytics/yolov5/discussions, where the community and our team can collaborate to identify the root cause and provide a resolution.

Thank you for the detailed information, and we appreciate your patience and contribution to improving YOLOv5.
