多行数据滑窗法数据增强python代码

以下是多行数据滑窗法数据增强的Python代码：

def sliding_window(data, window_size, stride):
    '''
    data: input data, shape (n_samples, n_features)
    window_size: size of the sliding window
    stride: stride of the sliding window
    '''
    n_samples, n_features = data.shape
    n_windows = (n_samples - window_size) // stride + 1
    windows = np.zeros((n_windows, window_size, n_features))
    for i in range(n_windows):
        windows[i] = data[i*stride:i*stride+window_size]
    return windows

其中，`data`为输入数据，形状为`(n_samples, n_features)`；`window_size`为滑动窗口的大小；`stride`为滑动窗口的步长。函数返回的是滑动窗口的数据，形状为`(n_windows, window_size, n_features)`，其中`n_windows`为滑动窗口的数量。
