Hello,
when I run object_detection_demo_yolov3_async.py with custom trained yolov3 tiny model, I'm experiencing the following error:

--------------------------------------
Environment:
Ubuntu 18.04 LTS
OpenVino 2020 R3 LTS
Python3.6
TF 1.11.0
I trained the Darknet Model using Intel CPU and I converted the wheights and PB to IR following the following instructions:
I suppose the problem is about .json file used with mo_tf.py to convert .pb to IR, anyway, eventually I don't see the issue.
Attached you can find the .cfg used to train the Model and the .json file used with mo_tf.py
Important Note: using the same data, procedure to train yolov3 model and to convert wheights and pb with NOT tiny, everything is working properly.
Please, do you have suggestions
Thank you

Hi Jesus, Hi Iffa,
problem solved using yolov3-tiny.conv.11
The object detection yolo v3 with my customization run properly recognizing masks
Thank you for your support

Greetings,
We had previously trained a yolov3-tiny on a custom dataset and the .json config has one small change when compared to yours.We suggest that you modify your json to match the following. The only difference is the "mask" values. Basically you would need to remove [3,4,5] and see if it makes a difference.
[

"id": "TFYOLOV3",
"match_kind": "general",
"custom_attributes": {
"mask": [0, 1, 2],
"anchors": [10, 14, 23, 27, 37, 58, 81, 82, 135, 169, 344, 319],
"classes": 2,
"num": 6,
"jitter": 0.3,

"entry_points": ["detector/yolo-v3-tiny/Reshape", "detector/yolo-v3-tiny/Reshape_4"]
}
}

We would really appreciate it if you could provide us the complete command that you had used with the model optimizer.
The key to finding the solution might be there.

Sure, please, see the command below and .json used attached:
sudo python3 mo_tf.py --input_model frozen_yolov3-tiny_workersafety_Intel_416_final.pb --tensorflow_use_custom_operations_config /opt/intel/openvino/deployment_tools/model_optimizer/extensions/front/tf/workersafety_yolo_v3_tiny_Intel.json --batch 1 --data_type FP16
To convert tf .weights to .pb, I followed the following great document you shared in the past that works fine with also other projects:
Please, let me know you opinion / suggestions

You need to specify "--input shape" parameter, e.g. >python3 mo_tf.py --input_model model.pb ^
--tensorflow_use_custom_operations_config yolo_v3_tiny.json --input_shape "[1, 608, 608, 3]"
Plus, it's better to replace --tensorflow_use_custom_operations_config with --transformations_config

In that case, can you share your model and files (.weights and .label) for us to try on our end.
You can share it privately if you don't want to attach it here.

Greetings,
We are able to reproduce your issue with the CPU plugin but the model runs on MYRIAD/GPU. However, We don't see any detections. Could you give us a sample image/video for us to test? This may be a bug on the CPU plugin.

Iffa

Hi Iffa,
thank you for your email.
Did you proporly convert the .pb to IR ?
You can use the images from Kaggle, links below:

Hi CBell1,
I was able to convert your model from weight -> .pb -> .xml/.bin. However, there is a RuntimeWarning: invalid value encountered in sqrt scale = 1. / np.sqrt(variance.data.get_value() + eps) from the model optimizer and ValueError when inferencing using the demo. Could you please verify your weight model is valid and can detect objects directly in DarkNet (assuming the model was trained on DarkNet)?
To convert from weight to .pb, I followed the instructions here.
To convert .pb to IR (.xml/.bin):
python3 /opt/intel/openvino_2021/deployment_tools/model_optimizer/mo.py --framework tf --reverse_input_channels --input_model frozen_darknet_yolov3_model.pb --batch 1 --transformations_config yolo_v3_tiny.json --data_type FP32
I tested the above steps with your model and the yolo_v3_tiny model available in pjreddie repository. These steps worked for model from pjreddie repo but not with your model. What base model did you use?

Jesus

Hi Jesus,
you recreated the similar error I have.
I followed the same steps you sent me (only difference is FP16).
Exactly, I used darknet53.conv.74 downloaded from pjreddie darknet
I cannot attach this file due to is ~150MB compressed.
Can the darknet53.conv.74 be corrupted?
Or with Yolo v3 Tiny should I use another model?

Hi Jesus, Hi Iffa,
I found a possible solution.
You are right there is something doesn't work with the pre-trained Weights model.
These are the official Yolo v3 darknet models:
With tiny I should use the second model instead the first that it's built for yolov3 (no tiny).
I test the yolov3-tiny.conv.11 with my custom solution and I'll keep you informed

Hi CBell1,
Glad you were able to solve your issue! Intel will no longer monitor this thread since this issue has been resolved. If you need any additional information from Intel, please submit a new question.

You can avoid this with a mask method. Note first that in python NaN is defined as the number which is not equal to itself:
>float('nan') == float('nan')
False
It might be worth avoiding use of np.NaN altogether. NaN literally means "not a number", and it cannot be converted to an integer. In general, Python prefers raising an exception to returning NaN, so things like sqrt(-1) and log(0.0) will generally raise instead of returning NaN. However, you may get this value back from some other library. From v0.24, you actually can. Pandas introduces Nullable Integer Data Types which allows integers to coexist with NaNs. Also, even at the lastest versions of pandas if the column is object type you would have to convert into float first, something like:
df['column_name'].astype(np.float).astype("Int32")
NB: You have to go through numpy float first and then to nullable Int32, for some reason.
