Failed to load 'yolov5n.onnx'.
miaowrx opened this issue · comments
hi,
I try to load 'yolov5n.onnx' like this:
#include "onnx.h"
int main(void)
{
struct onnx_context_t *sess = onnx_context_alloc_from_file("yolov5n.onnx", NULL, 0);
onnx_context_dump(sess, 1);
return 0;
}
but nothing was output, including warnings and errors.
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.
