It seems that you are trying to use the "sympy" module in Python but it is not defined. "sympy" is a third-party library for symbolic mathematics in Python and needs to be installed before it can be used. You can install it by running the following command in your terminal or command prompt:
```
pip install sympy
```
Once installed, you can import and use it in your Python code by adding the following line at the beginning:
```
import sympy
```

这个错误提示意味着你正在尝试使用 sympy,但是 Python 解释器并不知道 sympy 是什么。这可能是因为你没有正确地安装 sympy 或者没有将它导入到你的 Python 程序中。你可以尝试在 Python 程序中添加以下代码来导入 sympy:
```python
import sympy
```
如果你还没有安装 sympy,可以尝试使用以下命令来安装:
```
pip install sympy
```
请确保你的计算机已经安装了 pip。如果你正在使用 Anaconda,可以使用以下命令来安装:
```
conda install sympy
```
name 'sympy' is not defined
This error message usually occurs when the Sympy library has not been imported correctly. Make sure you have installed Sympy and imported it at the beginning of your code using the following line:
```
import sympy
```
If you have already imported Sympy and still encounter this error, make sure that you have spelled "sympy" correctly and that the library is correctly installed in your environment.
