vxVerifyGraph

[xiaodan7]

hi,I want to ask a question, hope you can help me
I used this routine
https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-acinto7/latest/exports/docs/vision_apps/docs/user_guide/APP_C7X.html

I modified the app_create_graph(AppObj *obj) in the main() function of the app_c7x_kernel function
I want the photos created to be RGB, and the output is also RGB
Therefore, I modified this variable
obj->input_img1 = vxCreateImage(obj->context, obj->width, obj->height, VX_DF_IMAGE_U8);
I changed VX_DF_IMAGE_U8 to VX_DF_IMAGE_RGB
obj->input_img1 = vxCreateImage(obj->context, obj->width, obj->height, VX_DF_IMAGE_RGB);

vxVerifyGraph() Reported an error
ERROR: Input/Output image format not correct !!!
0.2188s: VX_ZONE_ERROR:[ownGraphNodeKernelValidate:535] node kernel validate failed for kernel app_c7x_kernel.img_add at index 0
0.2206s: VX_ZONE_ERROR:[vxVerifyGraph:1947] Node kernel Validate failed

0.6728s: VX_ZONE_ERROR:[tivxObjectDeInit:180] Is kernel use failed
0.6753s: VX_ZONE_ERROR:[tivxObjectDeInit:276] Is error use failed

The error function is node->kernel->validate()
status = node->kernel->validate(node, node->parameters, num_params, meta);
The result of the statue is：-10

status ：-10 corresponds to the definition as：
VX_ERROR_INVALID_PARAMETERS = -(vx_int32)10,/*!< \brief Indicates that the supplied parameter information does not match the kernel contract. */

When the status is 0, it is successful
