Hi, I have this error when I run detect.py --visualize.
Any ideas why I have this error?

@ys31jp 👋 hi, thanks for letting us know about this possible problem with YOLOv5 🚀. We've tried to reproduce this issue but everything works correctly for us using your commands:

We've created a few short guidelines below to help users provide what we need in order to get started investigating a possible problem.

How to create a Minimal, Reproducible Example

When asking a question, people will be better able to provide help if you provide code that they can easily understand and use to reproduce the problem. This is referred to by community members as creating a minimum reproducible example. Your code that reproduces the problem should be:

• ✅ Minimal – Use as little code as possible to produce the problem
• ✅ Complete – Provide all parts someone else needs to reproduce the problem
• ✅ Reproducible – Test the code you're about to provide to make sure it reproduces the problem

For Ultralytics to provide assistance your code should also be:

• ✅ Current – Verify that your code is up-to-date with GitHub master, and if necessary git pull or git clone a new copy to ensure your problem has not already been solved in master.
• ✅ Unmodified – Your problem must be reproducible using official YOLOv5 code without changes. Ultralytics does not provide support for custom code ⚠️.

If you believe your problem meets all the above criteria, please close this issue and raise a new one using the 🐛 Bug Report template with a minimum reproducible example to help us better understand and diagnose your problem.

Thank you! 😃

@ys31jp
It may be a path problem in the windows operating system, so you should modify it appropriately. This does not exist on Mac and Linux.

Hi, thanks for prompt response. I test again. If I test with
python detect.py --visualize --source data/image.jpg
It work and nothing issues.

However if I test with
python detect.py --visualize --source data/image_0123.fr0123.jpg
The error will occurs.

#Zengyf-CVer Yes. It was due to the path issues.
if the image name is image_0123.fr0123.jpg in both Window and Ubuntu, it will generate the same error.

Because all of image name is somethings like this image_0123.fr0123. I have try to fixed this to check the feature map.
@glenn-jocher I implement this to fixed the issues. In plots.py, feature_visualization line 446 - 448.
I do test on both image name (image.jpg & image_0123.fr0123.jpg) and it works.

@ys31jp
Try to avoid the decimal point "." in the image name:
image_0123.fr0123.jpg

[ys31jp]

@ys31jp Try to avoid the decimal point "." in the image name: image_0123.fr0123.jpg

I cant. I have few k of dataset images with the ".". Which impossible for me to avoid.
