2 years ago 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, FreqAfter 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

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... czsc.sensors.pycache.plates.cpython-38: module MAY be using inspect.getsource czsc.sensors.pycache.stocks.cpython-38: module MAY be using inspect.getsource hist.scripts_gm_20211212.pycache.run_share_bt.cpython-38: module references file hist.scripts_gm_20211212.pycache.run_share_rt.cpython-38: module references file hist.scripts_gm_20211212.src.utils.pycache.bt.cpython-38: module MAY be using inspect.getsource 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 shlex
File "/usr/lib/python3.8/shlex.py", line 11, in
import re
File "/usr/lib/python3.8/re.py", line 124, 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!
