如图所示，在python3里面“import sympy”出现错误。
感谢报告，我们会尽快修复
谢谢！现在sympy本身是没问题了。我其实是尝试用octave的symbolic包做符号计算，sympy通了之后还是有问题，octave要求sympy版本至少为1.4。运行时的信息如下：

Symbolic package diagnostics
Python and SymPy are needed for most features of the Symbolic package.
The Python interpreter is currently: “python3”.
Computers may have more than one Python interpreter installed. If you
need to, you can select a different one using the PYTHON environment
variable (see “help sympref”). For example, to use Python 3, try
setenv PYTHON python3
sympref reset
Attempting to run python3 -c “print("Python says hello")”
status = 0
output = Python says hello
Good, Python ran correctly.
Python version
Let’s check what version of Python we are calling…
Attempting to run python3 -c “import sys; print(sys.version)”
status = 0
output = 3.10.13 (main, Apr 8 2024, 14:45:59) [GCC 13.2.0 20230727 (AOSC OS, Core)]
Running python3 -c “import sys; print(sys.executable)”
output = /usr/bin/python3
Checking if python3 is running in a Cygwin-like POSIX environment… no

SymPy Python Library
SymPy is a Python library used by Symbolic for almost all features.
Attempting to run python3 -c “import sympy; print(sympy.version)”
/usr/lib/python3.10/site-packages/sympy/solvers/diophantine.py:3188: SyntaxWarning: “is” with a literal. Did you mean “==”?

output = 1.3
SymPy must be at least version 1.4; you have version 1.3.
**** Your SymPy is too old! ****
Installed newer version already? Perhaps it was for a different Python?
Try “setenv” as described above to change your python interpreter.
不知AOSC的sympy版本是否有可能做一点升级？谢谢！
能行，这就安排！
