根据你提供的代码和错误信息，问题出现在ValueError: If mode is 'interp', window_length must be less than or equal to the size of x`这一行。这个错误是由于使用`savgol_filter`函数时，`window_length`参数的值大于了输入数组`x`的长度引起的。

根据你提供的代码，我们可以看到`x`的长度为160，而`window_length`参数的值为3。因此，导致了这个错误。

要解决这个问题，你可以将`window_length`参数的值设置得小于或等于输入数组`x`的长度，或者检查一下你的数据是否符合预期。
