I have ran the code freeze_graph.py and optimize_for_inference.py,and there is a final_network.pb generated, when I imported the final_network.pb in DNN with opencv,there is something wrong like this:

batch/fifo_queue:FIFOQueueV2
capacity:[ ]
component_types:[ ]
_output_shapes:[ ]
container:[ ]
shapes:[ ]
shared_name:[ ]
OpenCV Error: Unspecified error (Unknown layer type FIFOQueueV2 in op batch/fifo_queue) in populateNet, file /home/mi/opencv-3.4.0/modules/dnn/src/tensorflow/tf_importer.cpp, line 1487

what(): /home/mi/opencv-3.4.0/modules/dnn/src/tensorflow/tf_importer.cpp:1487: error: (-2) Unknown layer type FIFOQueueV2 in op batch/fifo_queue in function populateNet

Hi, I'm also getting a same error while loading "inception_v3_quant_frozen.pb" model in dnn tensorflow inception

Is it anyway to solve this issue?

Error log:

batch/fifo_queue:FIFOQueueV2

@Bala , please try a more recent opencv version (not 3.4.1) and see, if you can reproduce it

Hi Berak,

Got different error in OpenCV(3.4.3)

OpenCV(3.4.3) /usr/src/debug/opencv/3.4.1+gitAUTOINC+6ffc48769a_ced5aa7606_a62e20676a_34e4206aef_fccf7cd6a4-r0/git/modules/dnn/src/tensorflow/tf_importer.cpp:495: error: (-2:Unspecified error) Input layer not found: MobilenetV2/Conv/add_fold in function 'connect'
