I'm having similar issue with different model (in my case, the model is yolov3-tiny.onnx) .

I added ONNX_LOG calls to the onnx_graph_alloc function for debugging.

		if(!n->operator)
		{
			resolver_solve_operator(&resolver_default, n);
			if(n->operator)
			{
				n->r = &resolver_default;
				n->rctx = NULL;
			}
			else
			{
				ONNX_LOG("Unresolved!\r\n");
				ONNX_LOG("n->proto->op_type : %s\r\n", n->proto->op_type);
				ONNX_LOG("n->proto->name : %s\r\n", n->proto->name);
				ONNX_LOG("n->opset : %d\r\n", n->opset);
				ONNX_LOG("n->inputs[0]->type : %d\r\n", n->inputs[0]->type);
			}
		}
		if(!n->reshape)
			n->reshape = reshape_dummy;
		if(!n->operator) {
			n->operator = operator_dummy;
		}
		if(n->init)
		{
			if(n->init(n) <= 0)
			{
				ONNX_LOG("n->init failed\r\n");
				ONNX_LOG("i : %d\r\n", i);
				ONNX_LOG("n->proto->op_type : %s\r\n", n->proto->op_type);
				ONNX_LOG("n->proto->name : %s\r\n", n->proto->name);
				if(g->nodes)
				{

There're a few things I have noticed.

Resize operator is still not implemented.
Many operators such as Concat, input data type must be defined when resolving operators. But it looks like it's undefined before running the model.

I have same issue with Segmentation fault (core dumped).
model in https://github.com/Linzaer/Ultra-Light-Fast-Generic-Face-Detector-1MB
xxd convert onnx model to .h file, load model err in onnx_graph_alloc()
in onnx.c line 1171, model g->nlen = 242, but run end 82, and Segmentation fault.
