gather_nd_grad算子的输入index被设置为skip_transform,当fallback该算子时,index无法被正常拷贝回CPU,而index在计算中又是需要的,所以会出现segment fault。这里为index去除skip_transform属性,可解决这个bug。Enhance dtype support for the get_value operation. #57272 中为index引入skip_transform是因为当输入类型为complex时index被错误地提升为complex,而Update the logic of data_type transform for complex #59287 已修改transform datatype的逻辑使得int32、int64不会被错误提升为complex,所以这里删除index的skip_transform属性应该也不会有问题。使用npu复现的脚本如下,复现时需设置环境变量 export CUSTOM_DEVICE_BLACK_LIST=gather_nd_grad
