python报错
VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated.
If you meant to do this, you must specify 'dtype=object' when creating the ndarray.
a=np.array(newlist)#,dtype=object
这个错误提示的很明显了，加上dtype=object，其实加不加没啥影响，就是警告烦人
a=np.array(newlist,dtype=object)
