## error¶

Traceback (most recent call last):
File "E:/Program Files/PyCharm 2019.2/GraduationDesign/LSTM.py", line 193, in <module>
test(name, B)
File "E:/Program Files/PyCharm 2019.2/GraduationDesign/LSTM.py", line 180, in test
y_smooth = make_interp_spline(x, y[1:151])(x_smooth)
File "F:\Anaconda3\lib\site-packages\scipy\interpolate\_bsplines.py", line 795, in make_interp_spline
raise ValueError('x and y are incompatible.')
ValueError: x and y are incompatible.


## solution¶

The corresponding code in the original text is:

x = [i for i in range(1, 151)]
x_smooth = np.linspace(np.min(x), np.max(x), 900)
y_smooth = make_interp_spline(x, y[150:300])(x_smooth)


The error message x and y are incompatible obviously does not mean that the lengths of x and y are inconsistent, but that the shape is inconsistent: the shape of y is (150, 1), which requires Transpose it:

y_smooth = make_interp_spline(x, y.T[150:300])(x_smooth)
