这段代码是使用Python中的`open()`函数打开一个名为"游记正文.xlsx"的Excel文件，并尝试以UTF-8编码读取文件内容。然而，在第15至16个字节的位置上，存在无效的续字符，因此出现了UnicodeDecodeError错误。这通常是因为文件编码与指定的编码不匹配，或者文件本身存在无效的字符。你可以尝试使用其他编码方式来打开文件，或者检查文件内容是否包含非法字符。

这个错误通常是因为文件编码不是 UTF-8 导致的。你可以尝试指定文件编码格式来解决这个问题。例如，如果文件编码是 GBK，你可以这样修改代码： ```python with open(file_path, 'r', encoding='gbk') as f: ``` 如果你不确定文件编码是什么，你可以尝试使用 Notepad++ 等文本编辑器打开文件并查看编码格式。

UnicodeDecodeError Traceback (most recent call last) <ipython-input-8-b9eb148d8328> in <module> 1 if name == "main": ----> 2 transform_params_to_target() <ipython-input-6-76bc93c7b3b8> in transform_params_to_target() 1 def transform_params_to_target(): 2 with open("params.json", "r") as f: ----> 3 params = json.load(f) 4 target = [] 5 for obj in params: D:\AS\lib\json\init.py in load(fp, cls, object_hook, parse_float, parse_int, parse_constant, object_pairs_hook, **kw) 291 kwarg; otherwise ``JSONDecoder`` is used. 292 """ --> 293 return loads(fp.read(), 294 cls=cls, object_hook=object_hook, 295 parse_float=parse_float, parse_int=parse_int, UnicodeDecodeError: 'gbk' codec can't decode byte 0xa6 in position 184: illegal multibyte sequence

这个错误是因为你在使用 `json.load()` 时，文件的编码格式与 Python 解释器默认的编码格式不一致，导致解码失败。你可以通过指定文件编码格式的方式解决这个问题。例如，如果你的文件编码格式是 UTF-8，你可以将 `with open("params.json", "r")` 改为 `with open("params.json", "r", encoding="utf-8")`。另外，你也可以在文件头部添加指定编码格式的注释，例如 `# -*- coding: utf-8 -*-`，以确保 Python 解释器正确识别文件编码格式。
