OpenCV 3.4.1 : "Unknown layer type FIFOQueueV2 in op batch_join/fifo_queue" when loading pre-trained model .pb file

[a2bc]

Hello, I use OpenCV 3.4.1 to load the 20180408-102900.pb (https://drive.google.com/file/d/1R77HmFADxe87GmoLwzfgMu_HY0IhcyBz/view) by using the following code

std::string model = "20180408-102900.pb"; try { cv::dnn::Net m_network = dnn::readNetFromTensorflow(model); } catch (std::exception& ex) { std::cerr << ex.what(); }

and I get the error "Error: Unspecified error (Unknown layer type FIFOQueueV2 in op batch_join/fifo_queue) in cv::dnn::experimental_dnn_v4::`anonymous-namespace'::TFImporter::populateNet,"

When I use the python code of facenet, the loading of this .pb file is ok and I can validate on LFW correctly (https://github.com/davidsandberg/facenet/wiki/Validate-on-lfw)

I got the same issue with the pre-trained mode 20180402-114759 (https://drive.google.com/file/d/1EXPBSXwTaqrSC0OhUdXNmKSh9qJUQ55-/view): loading is ok with python code, but cannot work with OpenCV one.

Any idea?

Thank you !

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

Is it anyway to solve this issue? Error log:
