Questions about KeyError

[little-Paul-3]

Hi @jackd ，
I encountered a problem when I was learning your code. I read it in issues for a long time, and no one encountered this problem. I think I made a mistake in which step, but I didn't know about it, so I want to consult you, I would appreciate it if you could help me T^T
I encountered the following problem when I was training create_voxel.py:

Traceback (most recent call last):

Hope you can give me some advice, I've been stuck in preprocessing for a long time. Thanks a lot!

Well this is a blast from the past. Afraid I haven't worked on this for quite a while, but I'd suggest deleting any cached intermediaries. If a process that creates these cached files is interrupted while running, subsequent runs may see the partially processed files and interpret their presence as meaning the process finished, then run into trouble later. Not a perfect solution, but sufficed at the time. If you've done this and the error persists then I'll look into it further.

Hi @jackd,
I'm really glad to receive your reply! Thanks for your advice! I followed your advice to delete all cached files and reran the codes, but this key errors problem still exist......

However, I notice that the .hdf5 file generated by generate_mesh_data is unreadable code, which cannot be opened with any tool that reads such a file. I think maybe I use the wrong version of python or tensorflow.
Would you please tell me the version of python and tensorflow? Thanks a lot!

[jackd]

hmm... I've learned a lot about distributing code in the last 3 years, including the importance of specifying versions of things... alas that means I didn't know it when I wrote this repo. Can you try python 2.7 and tf 1.4? Pretty confident on the python version, not so much on the tf side of things.

Thanks!!! I will try it!!
