Completed 建模结束 上面的程序输出经过for line in iter(process.stdout.readline, b''): print(line) if "建模结束" in line.decode(): print('end')为什么会报这种错UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbf in position 0: invalid start byte

这个错误通常是由于尝试使用 `utf-8` 编码对无效的字节进行解码导致的。在处理输出时，可能会遇到一些无法使用 `utf-8` 解码的特殊字符，因此触发了这个错误。

为了解决这个问题，你可以尝试使用其他的编码方式来解码字节字符串，或者忽略无法解码的字符。下面是一个示例代码：

for line in iter(process.stdout.readline, b''):
    try:
        decoded_line = line.decode('utf-8')
        print(decoded_line)
    except UnicodeDecodeError:
        decoded_line = line.decode('utf-8', 'ignore')
        print(decoded_line)

在这个示例中，我们尝试使用 `utf-8` 编码来解码字节字符串。如果遇到无法解码的字符，我们使用 `'ignore'` 参数来忽略这些字符，并继续打印解码后的字符串。

通过这种方式，你可以避免由于无效字符导致的解码错误，并继续处理程序的输出。
