Question

当我尝试使用“ syms”功能运行某些文件时，出现此错误：

Traceback (most recent call last):
  File "<stdin>", line 4, in <module>
  File "<stdin>", line 12, in octoutput_drv
  File "<stdin>", line 55, in octoutput
  File "/home/vitorfrois/.local/lib/python3.8/site-packages/sympy/__init__.py", line 677, in __getattr__
    return getattr(self.mod, name)
AttributeError: module 'sympy.core.compatibility' has no attribute 'integer_types'
error: Python exception: AttributeError: module 'sympy.core.compatibility' has no attribute 'integer_types'
    occurred while copying variables to Python.
    Try "sympref reset" and repeat your command?
    (consider filing an issue at https://github.com/cbm755/octsympy/issues)

    StubCurto_Pit1OC at line 86 column 1

我已经尝试过“ sympref reset”并重复我的命令。然后，我收到另一个错误：


importing sympy.core.compatibility with 'from sympy import *' has been
deprecated since SymPy 1.6. Use import sympy.core.compatibility
instead. See https://github.com/sympy/sympy/issues/18245 for more
info.

这是输入功能

[dstub,lstub] = StubCurto_Pit1OC('StubCurto','Perm_r',1,'Freq',25e6,'ZLinha',50,'ZCarga',50 + 1j*75);

这是我正在使用的八度文件（“ syms”部分在第86行）

display('Comprimento do stub em curto em comprimentos de onda (Lambda)');
display(L_Lam_Stub)
display('Comprimento do stub em curto (m)'),display(lstub)

end

帮我解决syms pkg问题，以便我可以运行该功能而没有任何问题
