I tried np.append(A,B) but it doesn't keep the dimension, while the axis option causes the ValueError: all the input arrays must have same number of dimensions. | Append 2D array to 3D array, extending third dimension | 0.197375 | 0 | 0 | 65,088 |

I can't say definitively why this works, but it may have something to do with the cached module definitions that PyCharm uses to provide code hints.
