在处理数据的时候有一行代码卡了很久，我检查了一下程序发现卡在了这里。请问有什么解决方案吗？
When processing data, a line of code took a long time, and upon checking the program, I found that it was stuck here. What solutions do you suggest?

There are so many '*.gz' files under deep directory, thus the process is too slow.
Actually you can read cache_pluto_1M/metadata/cache_pluto_1M_metadata_node_0.csv directly to get the candidate dirs.
