How to retrain this material classifier? How to regenerate the training data?

[XiangyuSu611]

Hi Keunhong,

I’m trying to run PhotoShape, and I want to retrain the material classifier with other texture data. But I couldn't find the code to regenerate the training data, I found some clues in /src/terial/clasifier/README.md.The brdf_classifier folder does not exist in the current code version, can you send me the relevant code?

thank you very much!

Hi Xiangyu,

You can find the code to generate the data here: https://github.com/keunhong/photoshape/tree/master/src/terial/classifier/data

It is a distributed setup so you need to run the collector server and then run a worker process on any number of machines.

Once you have the rendering you can make the LMDB format dataset by running this script: https://github.com/keunhong/photoshape/blob/master/src/terial/classifier/data/make_lmdb.py

Hi Keunhong，

Sorry to interrupt again...

I have found some new textures from POLIIGON , but I found that the new textures cannot be used in rendering. After I modify the materials.json file, it cannot be used. I guess it is because the texture data is stored in the database. Do I need to modify the materials table in the database? If necessary, how do I generate the final sql file?

Thank you!

Hi Keunhong,

I encountered some problems again.

Now I have implemented the entire process of generating data. But when I run to here, I have found that some 'base_color_hist' don't exist. It's because I didn't add the json file describing the parameters when I created the new material data table. Will this affect the final generated data? If so, how do I get this json file?By the way, I use POLIIGON texture.

Thank you!
