ValueError: Mobile SSD models are expected to have exactly 4 outputs, found 2

[SamMakesIt]

I created a dataset using roboflow, and trained it using the colab. I have done this once before and it worked, but with this model i keep getting the ValueError: Mobile SSD models are expected to have exactly 4 outputs, found 2 error.

I met the same error in android sample object_detection.
