I'm running faster R-CNN in `matlab 2018b` on a Windows 10. I face an exception `CUDA_ERROR_ILLEGAL_ADDRESS` when I increase the number of my training items or when I increase the `MaxEpoch`.
Below are the information of my `gpuDevice`
CUDADevice with properties:
Name: 'GeForce GTX 1050'
Index: 1
ComputeCapability: '6.1'
SupportsDouble: 1
DriverVersion: 9.2000
ToolkitVersion: 9.1000
MaxThreadsPerBlock: 1024
MaxShmemPerBlock: 49152
MaxThreadBlockSize: [1024 1024 64]
MaxGridSize: [2.1475e+09 65535 65535]
SIMDWidth: 32
TotalMemory: 4.2950e+09
AvailableMemory: 3.4635e+09
MultiprocessorCount: 5
ClockRateKHz: 1493000
ComputeMode: 'Default'
GPUOverlapsTransfers: 1
KernelExecutionTimeout: 1
CanMapHostMemory: 1
DeviceSupported: 1
DeviceSelected: 1
And this is my code
latest_index =0;
for i=1:6
load (strcat('newDataset', int2str(i), '.mat'));
len =length(vehicleDataset.imageFilename);
for j=1:len
filename = vehicleDataset.imageFilename{j};
latest_index=latest_index+1;
fulldata.imageFilename{latest_index} = filename;
fulldata.vehicle{latest_index} = vehicleDataset.vehicle{j};
end
end
trainingDataTable = table(fulldata.imageFilename', fulldata.vehicle');
trainingDataTable.Properties.VariableNames = {'imageFilename','vehicle'};
data.trainingDataTable = trainingDataTable;
trainingDataTable(1:4,:)
% Split data into a training and test set.
idx = floor(0.6 * height(trainingDataTable));
trainingData = trainingDataTable(1:idx,:);
testData = trainingDataTable(idx:end,:);

finalLayers = [

else

end
save mix_data data
if doTrainingAndEval

resultsStruct = struct([]);
for i = 1:height(testData)
% Read the image.

% Collect the results.
resultsStruct(i).Boxes = bboxes;

end

results = struct2table(resultsStruct);
data.results = results;
save mix_data data
else

end
% Extract expected bounding box locations from test data.
expectedResults = testData(:, 2:end);
% Evaluate the object detector using Average Precision metric.

% Plot precision/recall curve
figure
plot(recall,precision)

First it prints the warning multiple time and throws the below exception

That should be okay. You could experiment with CUDA 10 driver instead, as long as you are not using cudamex() or GPU Coder.

This is what I expected but still, I’m getting this error. Could the memory size be an issue? Since I only have 8 Gig of memory
