Error of "unsupported operand type(s) for -: 'list' and 'list'"

When using min-max method on ECG data, we will encounter error of "unsupported operand type(s) for -: 'list' and 'list'".

Line 10, forecast_dataloader.py

Maybe the coder forgot to turn the list into numpy.ndarray, because he just use the z_score with data = (data - mean) / std. The data is numpy.ndarray, so it actually turns into - operand of numpy.ndarray.

So you can try
scale = np.array(norm_statistic['max']) - norm_statistic['min'] + 1e-5
instead of
scale = norm_statistic['max'] - norm_statistic['min'] + 1e-5

This is a useful trick.

Correct. I chose to turn the list into numpy.array before the - operation.
