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
bboxes = np.array(bboxes)

在调用opencv一句简单代码时

while cv.waitKey(1) < 0:

出现以下错误

E:\Anaconda3\envs\labelimg\lib\site-packages\numpy\lib\function_base.py:793: 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.
  return array(a, order=order, subok=subok, copy=True)

其实这不是错误，只是新版numpy的一个警告，可以忽略。当然总是显示影响美观，可以直接关闭该警告

np.warnings.filterwarnings(‘ignore‘, category=np.VisibleDeprecationWarning)
