IndexError in "notebooks/Neural NILM test"

[jhyun0919]

I am trying to run neural nilm in my pc environment, but the IndexError occurs like below. How can I fix it?

stride_source = StrideSource(
    target_appliance=TARGET_APPLIANCE,
    seq_length=SEQ_LENGTH,
    filename=NILMTK_FILENAME,
    windows=WINDOWS,
    sample_period=SAMPLE_PERIOD,
    stride=STRIDE
)

I'm sorry, I'm afraid I'm crazy busy with other work at the moment and so this repository is currently unsupported. Please see the README for more details.

@jhyun0919 were you able to run the notebooks and the core source code?

Downgrading pandas to 0.16.2 successfully fixed this issue for me
