Nothing showing on learning rate plot

I rean learn.lr_find(), and learn.recorder.plot(), and nothing shows on the graph. just the axis, title, but no actual line. In one of the lessons notebook, it says to run learn.lr_find(start_lr=1e-5, end_lr=1e-1) instead. I’ve tried that and nothing changed. What do I do now, what does this mean?

I’m having the exact same issue… I’m using gcp

EDIT: Turns out if I repeatedly run lr.find(), sometimes the plot actually works
