Pandas 无法读取 csv 文件，它将全部替换为 NaN

Question

我尝试读取 csv 文件

\n\n

 df = pd.read_csv("raccoons.csv", delimiter=":")\n df.head()\n

\n\n

它又回到了我身边

可能与文件编码有关。您可能必须在调用 read_csv 时设置此项。检查此处提供的解决方案以查找您的文件编码：UnicodeDecodeError whenReading CSV file in Pandas with Python

我遇到了同样的问题，最后使用以下方法解决了它：

pd.read_csv(..., encoding = 'utf-16')
