这个错误是因为在数据读取时使用utf-8编码,但是读取到了一个无效的字节序列。你可以尝试使用其他编码方式来读取数据,或者忽略这些无效的字节序列。例如:
```python
with open(fname, 'rb') as f:
for line in f:
try:
line = line.decode('utf-8').strip()
except UnicodeDecodeError:
continue
```
这样,当遇到无效的字节序列时,就会忽略这一行数据。

这个错误是因为在使用 Python 解析文件时,文件的编码格式与 Python 解析器的默认编码格式不一致,导致无法正确解码文件中的某些字符。在你的代码中,文件的编码格式是 GBK,但 Python 解析器的默认编码格式可能是 UTF-8。为了解决这个问题,你需要在打开文件时指定文件的编码格式,例如:
```
with open('filename.txt', 'r', encoding='gbk') as f:
for line in f:
# do something
```
在这个例子中,我们使用 `encoding='gbk'` 指定了文件的编码格式为 GBK,这样 Python 解析器就能正确解码文件中的字符了。你需要根据实际情况修改文件名和编码格式。

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。
