Re: Object Detection using Deep Learning

Hi Giuseppe,

 

The ‘Dedicated GPU memory usage’ graph monitors the GPU memory usage by applications. The graph shows that 5GB of 6GB available is being used. This also explains why 2GB video memory is not sufficient for the operator to run under.

 

Kind Regards

Jeff

Re: Object Detection using Deep Learning

Hi jdooley,

I'm trying to use Initialize Object Detection and I have some problem.

I run the procedure using 10 Training Steps and always end with successful. After that, I tried to run again the same model but with 100 Traing Steps. Unfortunately, the Spatial model execution failed.

 

Here, you can see the Session Log:

Where is the problem?

 

Thanks for your help,

Re: Object Detection using Deep Learning

[ Edited ]

Are you using your GPU to run the initialization? If so, I suspect you may be running out of GPU Memory.

 

You may turn off the GPU in the preference and run the initialization. It will take longer but will run to completion.

Re: Object Detection using Deep Learning

Hi Sam,

the problem was the GPU Memory.

I turned off the GPU and the run finished with successful.

 

Thanks,

Re: Object Detection using Deep Learning

It's not solved :-)

We are having problems also whan working on the CPU. The behaviour of these operators is still quite unstable and we have been spending a lot of time to make them working on. My colleague Nicolò will add other info about it.

Hi Giuseppe,

 

It sounds more like you ned to log a Support Ticket?

Re: Object Detection using Deep Learning

We have just finished a training for our customers.

We created the miz file on our machine (before the training) and then we built with the students the model for the object detection.
Every person had the same demo raster to classifiy (a little subset with some airplanes).

The model stopped on 4 computers on a total number of 32 computers. Everyone was working on CPU (cuda not enabled, restart erdas imagine).

We had the same behaviour while testing the model, before the training. On some computer it stops and we do not know why.

Re: Object Detection using Deep Learning

Do all the 32 computers have the same specs or are these 4 different?

Re: Object Detection using Deep Learning

These 4 computers were not the worst. They had 32 different notebooks.

I have, here in office, a notebook on which the model stops
