got error while running pretrain.py

Hi,

I’m trying to reproduce pretraining with config pretrain-tv-ht-16gpu.json

I got error messages as follows:

[1,4]<stderr>:Traceback (most recent call last):
[1,4]<stderr>:  File "pretrain.py", line 619, in <module>

So I printed that opts.

I think sub_txt_db should be SubTokLmdb, but it’s not…? I’m not sure. How should I fix this issue?

https://github.com/linjieli222/HERO/blob/00d8fbfada5f81062c43f0adfd0a570bf5814524/load_data.py#L36-L40

I can bypass this error message when I ignore L37-L39 and run L40.

Here is another issue https://github.com/linjieli222/HERO/blob/00d8fbfada5f81062c43f0adfd0a570bf5814524/pretrain.py#L50

should be modified to f"{opts.img_db}/{target['vfeat_db']}/{shard}", sub_txt_db, ?

@liveseongho

I have updated the utils/save.py to command out L23-24.

Please check if it works now.

@liveseongho Thanks for pointing out the issue and sorry about the inconvenience.

I will push a fix soon.
