openCL memory leak? #41

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Try pruning a network using a large NeuralDataSet (I use 1887 input - ideal 
pairs of market data)

What is the expected output? What do you see instead?
Pruning runs for about 15 mins and then I get this exception (I assume it is a 
memory leak)
