Dear all,

I am doing some tests with the new Deep Learning Object Detection Algorithm

I have an image (ECW, 3 bands, Worldview-3 pansharpened).

I have created the training dataset  (using ERDAS) using chips and footprint

The creation of the training set was ok. I created a new folder with all the chips (in tif format) and the xml (one for each tif).

If I try to use the Initialize Object Detection Operator ( I gave as input the folder with the chips and the xml) but I have this error:

14/12/18 15:38:16 SessionMgr(1828): Running command line: C:/Program Files/Common Files/Hexagon/SpatialModeler/16.5/bin/x64URelease/mlpywrapper_gpu.exe "C:/Program Files/Hexagon/ERDAS IMAGINE 2018/etc/MachineLearning/Operators/initializeobjectdetection.

Where am I going wrong?

thank you

The error message does not give enough clues on what went wrong. Please zip and send me the training images and associated xml files.

best regards, Sam

Thank you very much for your support Sam,

I am attaching my folder with the chips

Hi Giuseppe 

I run the training successfully with the data your provided me. Some of the xml files have a different path to the image. make sure the path tp the images specified in the xml file are correct.

I have sent you the machine intellect I generated via file catalyst.

Hello Sam,

thank you for your reply. I have created the chips in one shot.

I have copied all the paths in a text  file and it seems to me that they are ok:

<path>c:/share/deep_learning/object_detection_madrid/training_chip/Airplane1.tif</path>
<path>c:/share/deep_learning/object_detection_madrid/training_chip/Airplane2.tif</path>
<path>c:/share/deep_learning/object_detection_madrid/training_chip/Airplane3.tif</path>
<path>c:/share/deep_learning/object_detection_madrid/training_chip/Airplane4.tif</path>
<path>c:/share/deep_learning/object_detection_madrid/training_chip/Airplane5.tif</path>
<path>c:/share/deep_learning/object_detection_madrid/training_chip/Airplane6.tif</path>

<path>c:/share/deep_learning/object_detection_madrid/training_chip/Airplane14.tif</path>
<path>c:/share/deep_learning/object_detection_madrid/training_chip/Airplane15.tif</path>

What is the problem that you found?

thank you

Any news about this? Should I open a support ticket?

Thank you very much

Hi Giuseppe 

The only thing I did is change the path in the xml file to where I saved the images you sent me. And I run the initialization after that. Re-run it again and you can log a bug if you still reproduce the issue

Regards, Sam

Thank you Sam, I have just opened a ticket: 00037776

I solved the problem using a workstation with an NVIDIA graphic card with more memory. 

The computer that I was using and on which the operator does not work has a 2GB nvidia quadro graphic card.

Now I am working on a computer with a 6 GB GEFORCE graphic card and the operator Initialize Object Detection is working fine and it's very fast.
 
Now I am using the operator "Detects Object Using Deep Learning". I am working on the omputer with  6 GB graphic card. It seems to me that the operator it's not using the GPU. Is it a normal behaviour (not using the GPU)?

Thank you

Dear all,

I am doing many tests these days and I am experiencing a very strange behaviour of the Initialize Object Detection Operator.

Using the same input (100 tif images + 100xml footprints) and the same computer sometimes the model fails and sometimes not (I am tryng to create a demo workflow).

Have you experienced something similar?

Thank you

Regards
