Hi, Thanks for open source this interesting project. I have downloaded and preprocessed the MATR dataset, but I encountered an issue while converting the data to BatteryData, as shown in the third image. Do I need to convert the mat files to csv files, or is there another solution to this problem?

MATR_data Processed_Data BatteryData_Issue
opqrst-chen commented 4 months ago

Hello,

Thank you for raising this issue and for your interest in our project.

Regarding the handling of the MATR dataset, we have a separate implementation.

You can refer to the following commands to preprocess the MATR dataset of ".mat" file type: 

batteryml preprocess MATR /path/to/raw/data /path/to/processed/data

To load the processed data, you can use the following Python statement, which will load the resulting .pkl file: 

BatteryData.load("/path/to/processed/data/file")

Currently, the preprocess ARBIN command is unable to handle all CSV files in the MATR dataset due to errors encountered when processing certain files: "Cannot convert non-finite values (NA or inf) to integer: Error while type casting." We are actively working on inspecting and improving this functionality in future updates.

Thanks again for your feedback and for using our project!
