我的代码可以运行，但是当我调试时，它可以进入子程序。错误是：＆＃34;不支持解码Unicode＆＃34;。
我使用anaconda。当我打开untitled0.py时，屏幕底部的编码为UTF-8，但是当我打开fhmm_exact.py时，编码是UTF-8-GUESSED。

'''Disaggregate mains according to the model learnt previously.
Parameters
----------
mains : nilmtk.ElecMeter or nilmtk.MeterGroup
output_datastore : instance of nilmtk.DataStore subclass
For storing power predictions from disaggregation algorithm.
output_name : string, optional
The `name` to use in the metadata for the `output_datastore`.
e.g. some sort of name for this experiment. Defaults to
"NILMTK_FHMM_<date>"
resample_seconds : number, optional
The desired sample period in seconds.
**load_kwargs : key word arguments
Passed to `mains.power_series(**kwargs)`
