Simple Two Region Network Introspection test fails on 32bit Linux

bug

#1

When building NuPIC Core from source on 32 bit Linux, the SimpleTwoRegionNetworkIntrospection test case for nupic.bindings fails:

_____________ NetworkTest.testSimpleTwoRegionNetworkIntrospection ______________

self = <tests.network_test.NetworkTest testMethod=testSimpleTwoRegionNetworkIntrospection>

    def testSimpleTwoRegionNetworkIntrospection(self):
      # Create Network instance
      network = engine.Network()
    
      # Add two TestNode regions to network
      network.addRegion("region1", "TestNode", "")
      network.addRegion("region2", "TestNode", "")
    
      # Set dimensions on first region
      region1 = network.getRegions().getByName("region1")
>     region1.setDimensions(engine.Dimensions([1, 1]))
