I am working on hypersigma github below. Please refer to the link below. By the way I have a problem.

• HyperSIGMA github Link: https://github.com/WHU-Sigma/HyperSIGMA

The input is a dc.tif file downloaded from the site below, and I created two mat files (train_0.mat, train_1.mat) using the create_WDC_dataset function of ‘mat_data.py’. Then we tried to convert the two mat files (train_0.mat, train_1.mat) to the wdc.db file.
I tried to create the data.mdb, lock.mdb, meta_info.txt files in the wdc.db folder through the createDCmall function of lmdb_data.py, but the meta_info.txt file was not created. Below is the related error.

Any help is highly appreciated 👍

Thank U 😀

I’m looking forward to creating the following three files in the file path below.

• path: /data/project/hsi_foundation/HyperSIGMA/ImageDenoising/utility/WDC/wdc

wdc.db
