pandas 报错:【sys:1: DtypeWarning: Columns (15) have mixed types. Specify dtype option on import or set low_memory=False.】

错误原因

报错提示:“sys:1: DtypeWarning: Columns (15) have mixed types. Specify dtype option on import or set low_memory=False.”

错误:类型混淆

解决

import pandas as pd
pd = pd.read_csv(Your_path, low_memory=False)

关键点

low_memory

low_memory : boolean, default True

# 分块加载到内存,再低内存消耗中解析,但是可能出现类型混淆。
# 确保类型不被混淆需要设置为False,或者使用dtype 参数指定类型。
# 注意使用chunksize 或者iterator 参数分块读入会将整个文件读入到一个Dataframe,而忽略类型(只能在C解析器中有效)
