Question

我正在使用Numba CUDA来加速我的程序，但是遇到CUDA API错误，但没有错误消息。这是什么意思？输出如下：

CudaAPIError: cuModuleLoadDataEx error:

由于我试图将结果从一个CUDA内核传递到另一个CUDA，导致出现错误。这是摘要：

Dark_Pix_Search_Kernel[griddim, blockdim](d_all_bands, d_window1, d_result_holder_1)
print("DPS done")
median_filter[griddim, blockdim](d_result_holder_1, d_window1, d_result_holder_2) #<<< error here

d_result_holder_1是Dark_Pix_Search_Kernel的结果，然后将其传递到median_filter中。我们不允许这样做吗？

这是完整的追溯
