Hi,I have recentlt read your interesing work "Closing the Loop for Robotic Grasping: A Real-time, Generative Grasp Synthesis Approach" and have been trying to validate your results for a long time.However,I meet an error as below: 190317_1538ggcnn_9_5_3__32_16_8 1 368.0/1750.0 21.03% No pre-computed values.

When I run the file evaluate.py,it is ok at the begining and could print something.However,when it runs at epoch 10,it does not working well and print some errors as shown above.After then,I add a new file named epoch_00_model.hdf5 which is modified from the others into /networks/*.It continues to work.I do not know why.Could you please tell me some details about it?I am looing forward to your reply.

Hi there! Sorry about that... it looks like I was lazy with the file parsing and it only works up to epoch 99 (and is being confused by epoch 100). I'll fix the code properly, but for the time being if you delete epoch 100 it should be fine. There's unlikely to be any change after about epoch 50 anyway.
