When I used process.sh to extract project data, I found that the project was too large to be extracted. As a result, I modified extract.py to read the dataset paths in batches. Moreover, some datasets might have errors that prevent them from being parsed (it doesn't throw an error but just hangs, which was quite perplexing). Therefore, I added a time constraint, and if it exceeds a certain duration without processing, it skips. I hope this can assist users dealing with large volumes of data.
