Hi there!
It looks like you're running into an issue because the ResNetLayer
module isn't recognized within your YOLOv8 configuration. This could be happening if the ResNetLayer
isn't defined in your current environment or isn't properly imported in the script where you're trying to load the model.
Here are a couple of suggestions to troubleshoot and resolve this issue:
Check Module Name: Ensure that 'ResNetLayer' is the correct name of the module you're trying to use. If it's a custom layer, double-check that it's properly defined and imported into the script where you initialize YOLO
.
Verify Environment: Make sure that all necessary packages and custom modules are correctly installed in your working environment. If ResNetLayer
is part of an external library, it needs to be installed and accessible.
Alternative Import Method: If ResNetLayer
is defined in a file that isn't automatically imported, you may need to manually import it. For example:
from custom_layers import ResNetLayer # Adjust the import statement as per your setup
If you can share more about where ResNetLayer
is sourced from, I can provide more precise guidance! 👍
Thank you for your replies! I try to run the modified model from here #7270 , so I changed the layer inside the yolov8.yaml based on that model.
Hello!
Great to hear you're exploring by modifying the model! To ensure the ResNetLayer
is recognized, please make sure the layer is correctly defined and imported within the scripts you're working with. If this is a custom layer, verify its implementation and dependencies.
If the layer is part of a framework or external library, ensure that it's installed correctly and your import statements are set up right. Please share any specific errors you're encountering if issues persist. We're here to help! 😊
Happy coding!
Im not familiar with the steps to modify the model, can you help me to summarize what steps that I need to do for modifying the model? I thought by changing the yolov8.yaml's file is enough
Hey there! 🌟 Modifying the model primarily involves adjustments in the YAML configuration file, much like you've tried. However, it's also crucial to ensure that all components referenced in the YAML, such as new layers or module changes, are properly defined within the Python execution environment.
If you introduce new custom layers or modules (as seen with changes like 'ResNetLayer'), make sure these are correctly implemented and available in your environment. An example could be defining or importing a new layer:
from my_custom_layers import ResNetLayer
Modify your yolov8.yaml
to reflect these custom or adjusted elements, then retrain or run your model to see the changes in action. Let us know if you encounter any specific issues!

Question
Hello, Im new in computer vision and I was able to train the model successfully and I want to learn to modify the model but Im facing some errors. I tried to change the backbone of the model yolov8 by using resnet50 and here inside the yolov8.yaml "# Ultralytics YOLO 🚀, AGPL-3.0 license
