无法使用pd.to_datetime解析时间字符串

import pandas as pd

time_str = '2023-10-05 14:30:00'
try:
    datetime_obj = pd.to_datetime(time_str)
    print(datetime_obj)
except ValueError as e:
    print(f"Error: {e}")

import pandas as pd

time_str = '2023-10-05 14:30:00'
cleaned_time_str = time_str.replace(' ', '_')  # 替换空格为下划线
try:
    datetime_obj = pd.to_datetime(cleaned_time_str, format='%Y-%m-%d_%H:%M:%S')
    print(datetime_obj)
except ValueError as e:
    print(f"Error: {e}")

import pandas as pd

time_str = '2023-10-05 14:30:00+08:00'
try:
    datetime_obj = pd.to_datetime(time_str, utc=True)
    print(datetime_obj)
except ValueError as e:
    print(f"Error: {e}")

import pandas as pd

time_str = 1665397800  # 这是一个时间戳
try:
    datetime_obj = pd.to_datetime(str(time_str), unit='s')
    print(datetime_obj)
except ValueError as e:
    print(f"Error: {e}")
