如何连接2D numpy数组列表？

Question

I have a list of nested numpy arrays of shape (30,3). I tried to use numpy's vstack , hstack and concatenate , but I get an error: ValueError: all the input array dimensions except for the concatenation axis must match exactly

`[array([[[430, 110,  10],
    [ 62, 167,  10],
    [116, 136,  10],
    [341, 104,  10],
    [ 21, 116,  10],
    [371,  20,  10],
    [343, 197,  10],
    [ 59, 308,  10],
    [ 33,  23,  10],
    [215,  70,  10],
    [256,  73,  10],
    [ 94, 397,  10],
    [135, 251,  10],
    [202, 283,  10],
    [233, 313,  10],
    [319,  13,  10],
    [ 98, 273,  10],
    [261, 167,  10],
    [160, 296,   9],
    [137,  56,  10],
    [ 21, 320,  10],
    [ 77, 109,   9],
    [295, 356,  10],
    [178, 425,  10],
    [259,  35,   9],
    [319, 416,   9],
    [386, 331,   9],
    [319,  43,   9],
    [209, 409,   9],
    [115, 199,   9]]], dtype=uint16),` etc

I would like it to transform this into a normal list of lists, so getting rid of the array signs, just a plain list that I can easily manipulate.

Answer 1

If you want a plain list without the array signs, use <your_array>.tolist() The .tolist() will convert it to a plain list which is easily manipulatable. I hope this helps you
