PyCharm IDE problem

[ssqd2022]

Dear Developers:

When I extracted all the newest codes (2022-Jan-17) into PyCharm IDE (2021.3.1 Community Edition), and created a virtual Python 3.8 environment, it automatically detected that "Package requirements 'pyecharts>=1.9.0', 'tqdm', 'pandas>=1.1.0', 'zb>=0.0.14', 'numpy>=1.16.5', 'transitions', 'tushare', 'python-docx>=0.8.11','matplotlib','seaborn','Deprecated>=1.2.12' are not satisfied". This prompted me automatically install these package after clicking a button "Install requirements".

After such successful installation, I did run the following commands, within PyCharm IDE:

(1) setup.py --help

Successful, to see what commands I can run

(2) setup.py install

Most success, but with the following warning

reating 'dist/czsc-0.8.13-py3.8.egg' and adding 'build/bdist.linux-x86_64/egg' to it
zip_safe flag not set; analyzing archive contents...

hist.scripts_gm_20211212.src.utils.pycache.rt.cpython-38: module MAY be using inspect.getsource

(3) setup.py build

Successful, I saw the build directory with sub directories 'lib' and 'bdist.linux-x86_64' were created

(4) When I run the core code 'analyze.py' without any arguments or inputs, I got the following error:

Traceback (most recent call last):
File "/home/Downloads/czsc-master/czsc/analyze.py", line 3, in
import webbrowser
File "/usr/lib/python3.8/webbrowser.py", line 6, in

import enum
File "/home/Downloads/czsc-master/czsc/enum.py", line 3, in
from enum import Enum
ImportError: cannot import name 'Enum' from partially initialized module 'enum' (most likely due to a circular import)

(5) For the 'bar_generator.py' under the folder 'utils', it has the following statement:

from ..objects import RawBar, Freq

I know this is to import the 'object.py' within the parent folder ('czcs') of 'utils'. After running this code without any arguments or inputs, I got the following error:

/home/Downloads/czsc-master/venv/bin/python /home/Downloads/czsc-master/czsc/utils/bar_generator.py
Traceback (most recent call last):
File "/home/Downloads/czsc-master/czsc/utils/bar_generator.py", line 10, in
from ..objects import RawBar, Freq
ImportError: attempted relative import with no known parent package

I noticed that the library inclusion in this package uses folders and sub-folder structures, which causes "circular import" problem with PyCharm IDE.

I am curious that has anyone ever encounters such a problem? Or, what python IDE do you use, which does not have any problems such as "circular import".

Thank you for your attention! Your help will be highly appreciated!

There are not any "circular import" in czsc source code. As a third library, you should install czsc by pip install czsc or python setup.py install, then use it in your python console, for example:

import czsc
from czsc.objects import RawBar, Freq

After execute codes above, you will see version hints like:

欢迎使用CZSC！当前版本标识为 0.8.13@20220111

Thank you so much for your help.

Using your approach, I am able to compile all *.py files in "czsc/utilis" folder, except ta1.py.

File "/home/Downloads/czsc-master/czsc/utils/ta1.py", line 9, in
import talib as ta
ModuleNotFoundError: No module named 'talib

I also cannot find talib with "pip install talib".

Is this talib one of your own library? How should I import it?
