I converted a yolo-v3-tiny model to OpenVINO and then to a .blob file as shown in Easy_TinyYolov3_Object_Detector_Training_on_Custom_Data.ipynb, but even though I don't receive any error messages when I try to use the mode as described in the To run the .blob in DepthAI section, it doesn't show any output.

I would like to know how to train a MobileNetSSD model for OAK-1 Lite. I noticed that the existing notebooks for training MobileNetSSD are deprecated. Could you please provide any methods or guidance on how to proceed with training? Thank you for your help
Hi,

Hi
I am working on this project and I want to test it. The code works fine until the conversion starts. I receive multiple errors.
Can you please help with this and try to check the code ?
Thank you very much
I have custom trained a yolov7 and a yolov4-tiny model for detecting objects. I have made sure to follow all the recommended steps given in the DepthAI documentation regarding conversion of the model to blob format. Despite training well, my model makes very few detections when running on the stereocamera (most are wrong). However the model works fine when used with a simple webcam on the same live feed. This led me to believe that the problem must be with the conversion. I converted the yolov4-tiny model from .weights to .onnx using tensorrt_demos library, and later converted onnx to a 6 shave blob using https://blobconverter.luxonis.com/. For yolov7, I directly converted the weights from .pt to a 6 shave blob using https://tools.luxonis.com/. Has anyone else faced similar issues when training custom models? It would be great if anyone had any sort of insight.
please update the notebook as colab removed the support for tensorflow 1.x
this doesn't work anymore%tensorflow_version 1.x
Hello,
I've been trying to use YOLOv6 notebook and everything was okay until I got to training.
I get Can't get attribute 'SimConv' on <module 'yolov6.layers.common'
When I checked v6 repo, I found the following issue: meituan/YOLOv6#799
Turns out that new version was released v0.4.0 (yesterday), so the weights downloaded in notebook are not correct.
I did try to change the link to download 0.4.0 weights. Model then trained, but output from that can't be converted in blobconverter:
So I figured that something added in 0.4.0 is not supported and I'm writing this here. In the meantime, if anyone else is facing the same issue, just checkout tag 0.3.0 in notebook, and everything should work the same until release 0.4.0 is supported.
Hi I'd like some help converting the deeplabv3 series of models.
I was trying to use the blob converter tool.
I'm trying to convert http://download.tensorflow.org/models/deeplabv3_mnv2_pascal_trainval_2018_01_29.tar.gz, but am getting errors
Im using the following mo params:

with the default myriad compile params -ip U8
But get the following error:

i can't seem to run TensorFlow 1.x with google cob so i changed the code to TensorFlow_ versions 2.x. Now im getting this error contrib_training' is not defined error when trying to train
Could someone help me with my issue please
Hi team,
Just wondering do you have any plan for supporting the PyTorch models in the converter?
With such a popularity for PyTorch, it seems odd to not support PyTorch models.
I was okay to go with TF until I actually tried to train a custom model and received so many hurdles:
This is what I have experienced:
Hurdle 1
I followed the official tutorials for training a custom segmentation model here and here
and found they are all DEPRECATED(ctrl+c, ctrl+v without changing the cap).
Hurdle 2
I then followed the Roboflow colab notebook, then discovered that we need to apply for a token in order to use its script, which I cannot find...
Hurdle 3
I then created an account on their website and found some api keys and tried each(e.g. Publishable API Key), but none of them worked.
After hours searching, I gave up. it's just too much hustles to try to follow the tutorial to train our custom models with Tensorflow...
I then went to the blob converter website and found it does not even support PyTorch...
My suggestions:
Hello,
I have converted a custom trained yolov7 tiny model (13 classes and mAP=0.75, 1024x1024) into a blob with http://tools.luxonis.com/
I have used the blob following the instruction of YoloV7_training.ipynb notebook from [depthai-ml-training] repo with a OAK-D camera (connected to USB3 with/or without additional power supply)
I have 2 issues:
1) after few seconds I get an error. Why?
Traceback (most recent call last):
File "main.py", line 51, in
pv.prepareFrames()
File "/home/mz/Projects/ObjectDetection/depthai/depthai_sdk/src/depthai_sdk/managers/preview_manager.py", line 148, in prepareFrames
packet = queue.tryGet()
RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'color' (X_LINK_ERROR)'
2) before the error I see very few and bad detections even if the trained model gave very good results on the test set for static images (mAP~0.75). Why? Please see my Obs below: is that the reason?
Obs: The JSON note in https://github.com/luxonis/depthai-experiments/tree/master/gen2-yolo/device-decoding is not clear to me:
I have not changed the Json file of my model which is 1024x1024 as I do not understand WHERE I have to change the "side" entries: I have no side32 or side16 but many of them and all concerning the anchor masks. See attached my json file from the blob conversion: shall I do change something? how and where exactly? best.zip
Note: Values must match the values set in the CFG during training. If you use a different input width, you should also change side32 to sideX and side16 to sideY, where X = width/16 and Y = width/32. If you are using a non-tiny model, those values are width/8, width/16, and width/32.
Thank you in advance
Marco
Do you have any notebook on detection with custom data working on windows system ?
Also some of the code implemented in those notebook requires the object_detection library which works on numpy=1.18 while depthai requires numpy=1.21.
Thanks!
Hi,
the models git repo branch is not the main one, I tried calling a python script that converts the checkpoints to tflite format, but it doesn't exist in this branch.
What's the reason behind choosing this one? Is it just the only one that worked for you ?
Thanks
This is a custom trained model on edgeimpulse.com which provides a Tensorflow SavedModel as well as a Tensorflow Lite Model at the end of the training. The issue is converting a Tensorflow SavedModel to a Luxonis Blob model by first Freezing the Tensorflow Saved Model and then trying to use https://blobconverter.luxonis.com/.
These are my files:
SavedModel file:
SavedModel.zip
Tflite file:
Tflite_file.zip
Sorry for opening this issue since it might have come up several times, but none of the solutions seemed to solve my issue. I've dropped the files in case it works for you'll. Sometimes it does convert, but doesn't work while running on OAK-D. For reference, there are 5 labels in the model and it is built on Mobilenet framework.
Code to freeze the SavedModel:
import tensorflow as tf
# Load the saved model
loaded = tf.saved_model.load("/content/saved_model/")
# Extract the graph
graph = tf.function(loaded.signatures[tf.saved_model.DEFAULT_SERVING_SIGNATURE_DEF_KEY]).get_concrete_function(tf.TensorSpec(shape=[1, 320, 320, 3], dtype=tf.float32))
frozen_graph = graph.graph.as_graph_def()
# Save the frozen graph
with tf.io.gfile.GFile("/content/frozen_model.pb", "wb") as f:
f.write(frozen_graph.SerializeToString())
Error I get with blobconverter:
[ ERROR ] Cannot infer shapes or values for node "StatefulPartitionedCall".
[ ERROR ] Expected DataType for argument 'dtype' not None.
[ ERROR ]
[ ERROR ] It can happen due to bug in custom shape infer function <function tf_native_tf_node_infer at 0x7f99c67e1af0>.
[ ERROR ] Or because the node inputs have incorrect values/shapes.

For more information please refer to Model Optimizer FAQ, question #38. (https://docs.openvino.ai/latest/openvino_docs_MO_DG_prepare_model_Model_Optimizer_FAQ.html?question=38#question-38)
This is apparently what I used and it converted it successfully to .xml and .bin files, however the .xml file was just 2 Kb and the .bin file was 0 Kb
Output while conversion:
[ INFO ] The model was converted to IR v11, the latest model format that corresponds to the source DL framework input/output format. While IR v11 is backwards compatible with OpenVINO Inference Engine API v1.0, please use API v2.0 (as of 2022.1) to take advantage of the latest improvements in IR v11.
Find more information about API v2.0 and IR v11 at https://docs.openvino.ai/latest/openvino_2_0_transition_guide.html
[ SUCCESS ] Generated IR version 11 model.
[ SUCCESS ] XML file: /content/saved_model.xml
[ SUCCESS ] BIN file: /content/saved_model.bin
Nevertheless, I tried to convert to a blob file and it converted it to a 1Kb file and when I tried to run it, the NN size was displayed to be 3x320 which was absurd since it was trained on 320x320 images [1,320,320,3] format.
I reran the conversion again using:
!mo --input_shape [1,320,320,3] --saved_model_dir /content/saved_model/ --layout "ncwh->nhwc"
However, this time when I converted it to blob and used it while running, it gave me an error stating the bounding boxes contain x=1,y=0,w=0,h=0.
Code:
import tflite2onnx
tflite_path = '/content/trained.tflite'
onnx_path = '/content/model.onnx'
tflite2onnx.convert(tflite_path, onnx_path)
Error:

But after that, while converting it to blob using blobconverter, this is the issue:

For more information please refer to Model Optimizer FAQ, question #61. (https://docs.openvino.ai/latest/openvino_docs_MO_DG_prepare_model_Model_Optimizer_FAQ.html?question=61#question-61)
I'm completely stuck and have tried everything I could and hoping there is some workaround. Any workaround on converting this to blob would be really helpful since I'm completing the project under a narrow time constraint.
Thanks a lot. Your help is really appreciated!

I'm using this colab notebook to train a YoloV6N model.
As shown in the notebook, I train my model and then download my pytorch weights. I then use the online tool to convert it to blob format, which is failing (as shown below). Pt weights here
I've also tried "640 352" in the field "Input Shape", but to no avail.
I attempted to use this notebook, https://github.com/luxonis/depthai-ml-training/blob/master/colab-notebooks/Easy_Object_Detection_With_Custom_Data_Demo_Training.ipynb, to train a model on and received the following error.
I attempted to clear all outputs, disconnect and clear out my session and tried again but with the same results when I get down to starting the training. Is there a library that should be loaded that is being skipped or a work around.

Hi,
I trained the model above on custom dataset. I tried next to use google API to convert to tflite, but it fails.
ValueError: ssd_mobilenet_v2 is not supported. See `model_builder.py` for features extractors compatible with different versions of Tensorflow
Can someone please help me ?
After custom training and tried to run blob file with OAK-D WiFi but there is no detections.
Could you explain what I've done wrong? the converted blob file I placed in nn folder. Change all labels in Python Script according docu. Also tried to reduce IoU and threshold to 0.1 but there is no detection. With colab test yolov4-tiny works fine. OpenVino convertingI couldn't verify (newby)
In tutorials I've found different versions of OpenVINO (2021_1 and 2021_2). For my tests I use 2021_1 because I couldn't find how to download with wget the version from februar or march.
I've tried two different example scripts (from colab notebook and from docu)
I have:
Could you help me to solve my issue.
Thank you!
And it were very great if you could provide me a link with actual documentation, because many hyperlinks are "dead"
When running the Colab there is an error in stage "Install Tensorflow Object Detection API":
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd
I tried different solutions. When I install numpy 1.20.0 this stage works, but it fails later in the training.
This still worked about 3 weeks ago.
Can you fix it again?
I'm using this colab notebook to train a YoloV6N model.
The pt model I get worked perfectly, like this
As shown in the notebook, I train my model and then download my pytorch weights. I use the online tool to convert it to blob format. I then use this file to check the inference of this blob model on the same image.
Unfortunately, I get extremely bad results, as shown here
This doesn't look like a problem to be solved with IoU threshold change (since I see no correct bounding boxes around objects at all)
I use "640" and "640 640" both in the online tool for converting pt to blob model. It didn't fix the issue (in the colab training notebook, I used "--img-size 640" for training).
Can someone please help with this?
Followed this Deeplab V3 Plus Mobile Net V3 notebook
Changed nothing and just went through all procedure to see whether it can yield a re-trained AI model.
It does generate an AI model and also converted the model to .blob
file.
I then use this generated model with depthai
project to test it on my OAK-D camera. It returns me an error:

device.startPipeline(pm.p)
RuntimeError: Device booted with different OpenVINO version that pipeline requires
I then downgraded my depthai
to 2.7.0.0 and it throws another error:
I then updated the requirements.txt
to have
depthai==2.7.0.0
Then re-ran the command line and the same error happens again

Hi, I ran into these dependency conflicts last week, along with the "numpy has no attribute 'int'" and worked through them. I don't know if its worth it to update the Colab notebook as these things continue to change but this install string resolved the issue. A lot of it was specifying the highest levels without going over routine.
!pip install -U -q torch==1.13.0 torchvision>=0.9.0 protobuf==3.19.5 numpy==1.23.1 opencv-python>=4.1.2 PyYAML>=5.3.1 scipy>=1.4.1 tqdm>=4.41.0 addict>=2.4.0 tensorboard==2.9.0 pycocotools>=2.0 onnx>=1.10.0 onnx-simplifier>=0.3.6 thop
Thank you guys for all of the hard work you've put into this, though. ๐ It must be a mess keeping all of these code iterations together.

Hi,
In the second to last step, the script to fix the XML file outputs an error due to the layer name change. Below is the change I used to resolve the error.
WAS:
data = root.find('.//layer[@name="strided_slice_10/extend_end_const1245431561"]/data')
IS:
data = root.find('.//layer[@name="strided_slice_10/extend_end_const1245431174"]/data')

Hello!
I am working with the OAK-D-PoE camera. Currently, I have successfully integrated the YOLO v7 neural network into this camera using the tutorial provided on GitHub (https://github.com/luxonis/depthai-experiments/tree/769029ea4e215d03f741bcf085d1bb6c94009856/gen2-yolo/device-decoding).
Could you please advise if it's possible to add post-processing directly to the camera, so that neural network processing -> post-processing -> data transmission to the computer occurs within the camera itself?
I would greatly appreciate your response and any advice on how to accomplish this.
Thank you in advance for your assistance.
Hello!
I was trying to follow the step within the YOLOv8 colab and found an error in the final steps, when trying to run the camera with the obtained model.
Likewise, the same happened when I tried to run the Yolov7 object detection colab. Here is the error trace.
