网上有很多关于lstm时间序列的博客，我从不同博客那里借鉴了许多。
理论知识：
项目已开源上传到gitee上：
时间序列预测仓库: 本项目从简单入门到涉及部分高级预测代码，正在维护中，涉及单变量单步预测，单变量多步预测，以及多变量单步预测，多变量多步预测。 (gitee.com)
1.首先是构建时间序列数据，然后转化为监督学习数据集。
series_to_supervised()函数
from pandas import DataFrame
from pandas import concatdef series_to_supervised(data, n_in=1, n_out=1, dropnan=True):
"""
Frame a time series as a supervised learning dataset.
Arguments:
data: Sequence of observations as a list or NumPy array.
n_in: Number of lag observations as input (X).
n_out: Number of observations as output (y).
dropnan: Boolean whether or not to drop rows with NaN values.
Returns:
Pandas DataFrame of series framed for supervised learning.
"""
n_vars = 1 if type(data) is list else data.shape[1]
df = DataFrame(data)
cols, names = list(), list()
# input sequence (t-n, ... t-1)
for i in range(n_in, 0, -1):
cols.append(df.shift(i))
names += [('var%d(t-%d)' % (j+1, i)) for j in range(n_vars)]
# forecast sequence (t, t+1, ... t+n)
for i in range(0, n_out):
cols.append(df.shift(-i))
if i == 0:
names += [('var%d(t)' % (j+1)) for j in range(n_vars)]
else:
names += [('var%d(t+%d)' % (j+1, i)) for j in range(n_vars)]
# put it all together
agg = concat(cols, axis=1)
agg.columns = names
# drop rows with NaN values
if dropnan:
agg.dropna(inplace=True)
return agg2.
