这个错误信息提示最近的调用是在C:/Users/86156/Desktop/.2.py的第24行,plt.imshow函数出现了问题,可能是由于norm参数的值不正确引起的。此外,还设置了interpolation、vmin和vmax等参数。

PS C:\Users\15094\Desktop\MESDEMO> & C:/Users/15094/AppData/Local/Programs/Python/Python38/python.exe c:/Users/15094/Desktop/MESDEMO/ui.py Traceback (most recent call last): File "c:/Users/15094/Desktop/MESDEMO/ui.py", line 3, in <module> class CommunicateServer(QObject): File "c:/Users/15094/Desktop/MESDEMO/ui.py", line 6, in CommunicateServer self.server = QTcpServer() NameError: name 'QTcpServer' is not defined
这个错误提示表明在你的 Python 代码中,使用了一个未定义的名称 QTcpServer。
QTcpServer 是 PyQt5.QtNetwork 模块中的一个类,它提供了一个 TCP 服务器。因此,你需要在代码中导入 PyQt5.QtNetwork 模块并且使用 QTcpServer 类。
你可以在代码开头添加以下导入语句来解决问题:
```
from PyQt5.QtNetwork import QTcpServer
```
这样就可以在你的代码中使用 QTcpServer 类了。
Traceback (most recent call last): File "C:/Users/DSX/Desktop/st0601.py", line 6, in <module> calculate(m) File "C:/Users/DSX/Desktop/st0601.py", line 3, in calculate avg = sum(args) / len(args) ZeroDivisionError: division by zero
这个错误提示意味着你传递给函数的参数列表 args 是空的,因此在计算平均值时出现了除以零的情况。你需要检查一下传递给函数的参数是否正确。如果 args 为空,你可以在函数中添加一些代码来处理这种情况,例如返回一个默认值或者抛出异常。以下是一个处理这种情况的示例代码:
```python
def calculate(*args):
if len(args) == 0:
return 0
else:
avg = sum(args) / len(args)
return avg
```
在这个例子中,如果参数列表为空,函数会返回0。否则,它将计算平均值并返回结果。
