Is it possible to disable multi-process to make debugging easier?

[fuchen]

When customize my own dataset, I need to print some debug values. But due to the multi-process execution, I cannot see these debug values. How can I disable multi-process execution?

Try changing line 92 in qlib/config.py to qlib.init(kernels=1), which means that the number of processes is set to 1. And combined with #477 mentioned method.
