6 years ago I'm sorry to reply you so late. It is caused by the length of cfg.CLASSES is not same as the size of the output layer of the weightsfile. You use weightsfile for coco to tarin voc dataset. If this, the weights of output layer don't restore.
Hi Leeyoshinari ! When I tried to run the code you provided, there were always some fault tips occurring. Like:
