OpenCV cannops error: driver error, feature not supported

[SHL2023]

Hi ,I created a Docker container on Atlas 500 A2（ascend310b）, installed cann-toolkit_7.0.0 and operator package cann-kernels-310b_7.0.0 inside it, then compiled OpenCV 4.10.0 with the cannops module. When running the sample program, it reported an error:

terminate called after throwing an instance of 'cv::Exception' 

  what():  OpenCV(4.10.0) /home/opencvcompile/opencv_contrib-4.10.0/modules/cannops/src/cann_call.cpp:97: error: (-2:Unspecified error) in function 'aclrtMemcpy2dWarpper' 

> EL0014: The operation is unsupported. 

>         TraceBack (most recent call last): 

>         rtMemcpy2d execute failed, reason=[driver error:feature not support][FUNC:FuncErrorReason][FILE:error_message_manage.cc][LINE:50] 

>         [Synchronized][Memcpy]synchronized memcpy failed, kind = 1, runtime result = 207000[FUNC:ReportCallError][FILE:log_inner.cpp][LINE:161] 

Could you take a look?@hipudding
