2. 修复问题

1. backtesting/_plotting.py:250:ValueError: failed to validate DatetimeTickFormatter(id=‘p1046’, …).days: expected a value of type str, got [‘%d %b’, ‘%a %d’] of type list

# /Users/xx/opt/anaconda3/envs/backtesting_test/lib/python3.12/site-packages/backtesting/_plotting.py:250
# formatter=DatetimeTickFormatter(days=['%d %b', '%a %d'],
#                                months=['%m/%Y', "%b'%y"]),
formatter=DatetimeTickFormatter(days='%d %b',
                              months='%b %Y'),

2. backtesting/_plotting.py:458: FutureWarning: ‘M’ is deprecated and will be removed in a future version, please use ‘ME’ instead.

# /Users/xxx/opt/anaconda3/envs/backtesting_test/lib/python3.12/site-packages/backtesting/_plotting.py:445
dict(day='ME',  # 修改这里：从 'M' 改为 'ME'

3. backtesting/test/init.py:8: FutureWarning: The argument ‘infer_datetime_format’ is deprecated and will be removed in a future version. A strict version of it is now the default, see https://pandas.pydata.org/pdeps/0004-consistent-to-datetime-parsing.html. You can safely remove this argument.
   return pd.read_csv(join(dirname(file), filename),

# /Users/xxx/opt/anaconda3/envs/backtesting_test/lib/python3.12/site-packages/backtesting/test/__init__.py:8
return pd.read_csv(
