在熊猫中转换日期时间

Question

我具有以下日期时间格式（2018年2月2日6:35:52 AM），我想将其转换为％Y-％m-％d％H：％M：％S.％f格式，例如：2017-05-13 21：11：01.436757

我已经尽了一切努力，但遇到错误

customer_file_path['RECEIVED_DATE2'] = customer_file_path['RECEIVED_DATE'].str.replace(',','')
print(customer_file_path[['RECEIVED_DATE2']].head(10))
customer_file_path['RECEIVED_DATE2'] = pd.to_datetime(customer_file_path['RECEIVED_DATE2'], format='%b %e %Y %-I:%M:%S %p', errors='coerce')
print(customer_file_path[['RECEIVED_DATE2']].head(10))

customer_file_path['RECEIVED_DATE3'] = pd.to_datetime(customer_file_path['RECEIVED_DATE2']).dt.strftime('%Y-%m-%d %H:%M:%S.%f')#, errors='coerce')
customer_file_path['RECEIVED_DATE2'] = pd.to_datetime(customer_file_path['RECEIVED_DATE2'], format='%b %e %Y %-I:%M:%S %p').dt.strftime('%Y-%m-%d %H:%M:%S.%f')#, errors='coerce')
