Environment setup confusions

[Imbernoulli]

🐛 Bug Description

Only using pip install pyqlib always can't really prepare necessary environment.
If I only do condo create and pip install pyqlib, even the data retrieve process can's work.
It will show ImportError: cannot import name 'init' from 'qlib' (/Users/bernoulli_hermes/opt/anaconda3/lib/python3.9/site-packages/qlib/__init__.py).
And when using models except LightGBM, other troubles will happen, like torch is not installed. Which shouldn't happen when a user go along with your guide.

And if I use the other alternative to build the environment, I need to go to the source package to build it. But this process is not mentioned in your guide, which is not friendly to newcomers.

And a embarrassing thing is when I run cd scripts && python collect_info.py all, it says that my Mac is x86-64, which is truly arm64.

I'm on Mac M1.

I meet this problem too!

My ad-hoc solution is to change this code

qlib/qlib/tests/__init__.py

Lines 8 to 9 in 78b77e3

	from .. import init
	from ..constant import REG_CN, REG_TW

into this

from qlib import init
from qlib.constant import REG_CN, REG_TW
