Preprocessed Data Path for BP4d+ #237

Closed amishparekh closed 7 months ago

amishparekh commented 7 months ago

Hi, Due to huge size of the data of BP4D+, we are getting some ram issues.. Is it possible to share the data directory structure for preprocessed BP4d+ dataset. We wanted to try out the models and hence trying to tweak some codes as well, but not able to understand the structure of the preprocessed BP4d+.. I guess because of the RAM we are not able to load the data.

Hi @amishparekh,

I'm personally not too familiar with that dataset, but have you already referenced the information in the BigSmall repo on preprocessing here? Also, for reference, the BP4D+ dataset's directory structure should be this as per our toolbox's README:

Not sure if that helps. @girishvn should be able to reply back to this issue when he has time to.

Hi @amishparekh,

Sorry for the late reply. As @yahskapar mentioned, the above is the directory structure of the BP4D+ dataset

The preprocessed data directory structure of BP4D+ is very similar to that of the other datasets in this tool box. It is as follows:

BP4D_BigSmall_Preprocessed_DataDir | |-- F001T1_input0.pickle | |-- F001T1_label0.npy | |-- M001T8_input0.pickle | |-- F001T8_label0.npy | |-- F001T10_input0.pickle | | ...

Note that for BP4D+ the input file is a pickle format - a dictionary holding the video frames and the corresponding labels values.

Hope the above helped. Closing this issue - feel free to open it if something comes up.
