I'm using tensorflow1.10 on ubuntu18.04. how can i fix this problem

Traceback (most recent call last):

Hi, I also encountered the same issue. Do you solve this problem?

[Axiss]

@qingping95 sorry, i didn't solve it. it's probably caused by TF version. I’m using faster-rcnn.pytorch. https://github.com/jwyang/faster-rcnn.pytorch

@CodeForWuyu Yeah, You are right! I just now solved it by changing my tensorflow version to 1.8.1. Thank you for your reply.

I was able to make it work for TF 1.10.1 after making the following changes:

add the following lines to lib/roi_pooling_layer/roi_pooling_op.cc

#include "tensorflow/core/framework/shape_inference.h"
...
.Output("argmax: int32")
.SetShapeFn([](::tensorflow::shape_inference::InferenceContext* c) {
//https://github.com/tensorflow/.../core/framework/shape_inference.h
int pooled_height;
int pooled_width;
c->GetAttr("pooled_height", &pooled_height);
c->GetAttr("pooled_width", &pooled_width);
auto pooled_height_h = c->MakeDim(pooled_height);
auto pooled_width_h = c->MakeDim(pooled_width);
auto output_shape = c->MakeShape({ c->Dim(c->input(1), 0), pooled_height_h, pooled_width_h, c->Dim(c->input(0), 3) });
c->set_output(0, output_shape);
return Status::OK();
});
