Metrics for YOLOv8 model
Closed this issue · 6 comments
Will user metrics ever be supported for YOLOV8 or is it expected that I use a COCO callback?
I also opened this issue in the Keras Repo and they suggested I move it here.
keras-team/keras#19416
Current Behavior:
When I compile a YOLOv8 model with metrics I get an error
model.compile(
classification_loss="binary_crossentropy",
box_loss="ciou",
optimizer=optimizer,
metrics = [keras.metrics.Recall(), keras.metrics.Precision()]
)
ValueError: User metrics not yet supported for YOLOV8
Expected Behavior:
Adding the requested metrics
Steps To Reproduce:
Version:
Keras version: 3.1.1
Keras_cv version: 0.8.2
It should be supported. Using callbavk for this is ineffective approach.
Any updates?
While we're waiting for the resolution of this issue, is there an alternative ? I see callbacks mentionned, but do you really have to "manually" (as in with an explicit "for" loop) infer on the validation dataset and then compute and store the metric ? I'm sorry if the question is dumb I don't have much experience yet.
Loss and Box Loss are calculated automatically. I don't think you can write an explicit for loop, but I believe you would need to write a custom callback for Recall and Precision.
Any updates on this?
Right now looks like coco metrics is hardcoded. We don't have plans of adding more. For your usecase I would suggest subclassing and adding custom callback.
