detailed_workflow.ipyb collector.py not working

❓ Questions and Help

Thank you for making this tool.
I am learning the ropes and was going through [\examples\tutorial\detailed_workflow.ipynb](https://github.com/microsoft/qlib/blob/main/examples/tutorial/detailed_workflow.ipynb)

I am stuck at at cell where it is suppose to download extra data

if not p.exists():
    !cd ../../scripts/data_collector/pit/ && pip install -r requirements.txt
    !cd ../../scripts/data_collector/pit/ && python collector.py download_data --source_dir ~/.qlib/stock_data/source/pit --start 2000-01-01 --end 2020-01-01 --interval quarterly --symbol_regex "^(600519|000725).*"
    !cd ../../scripts/data_collector/pit/ && python collector.py normalize_data --interval quarterly --source_dir ~/.qlib/stock_data/source/pit --normalize_dir ~/.qlib/stock_data/source/pit_normalized
    !cd ../../scripts/ && python dump_pit.py dump --csv_path ~/.qlib/stock_data/source/pit_normalized --qlib_dir ~/.qlib/qlib_data/cn_data --interval quarterly

I just stays at stalls for a couple hrs and does not download the data. You can see the output here -

I am on win11 and tried it on linux too but it did not help.
I tried to debug it but its taking very long as I am new to the tool. Please can someone guide me on this.

Start with examples/tutorial/detailed_workflow.ipynb and reproduce the data-download cell, then compare its output with the linked gist. Read scripts/data_collector/pit/collector.py and scripts/dump_pit.py to identify where execution stalls. Done means the PIT data downloads, normalizes, and reaches the dump step on the reported environments, or the issue documents a specific reproducible failure.
