Met "Check failure stack trace: " when running Caffe

I use python (The IDE is Pycharm) to run a net and a pretrained model to get 8 outputs. The code is like this:

myNet = root + netName
myModel = root + modelName
net = caffe.Net(myNet , myModel , caffe.TEST)

The net is really simple:

name: "Trial"
layer {
    name: "data"
    type: "MemoryData"
    top: "imgPairsSubMean"
    top: "boundings" 
    memory_data_param {
        batch_size: 1
        channels: 2
        height: 64
        width: 64
      }
    include {
        phase: TEST
    }
}

layer {
    name: "conv1"
    type: "Convolution"
    bottom: "imgPairsSubMean"
    top: "conv1"
    param {
        lr_mult: 1
    }
    param {
        lr_mult: 2
    }
    convolution_param {
        num_output: 1
        pad: 1
        kernel_size: 3
        stride: 1
        weight_filler {
            type: "xavier"
            std: 0.01
        }
        bias_filler {
            type: "constant"
            value: 0
        }
    }
}
layer {
    name: "relu1"
    type: "ReLU"
    bottom: "conv1"
    top: "conv1"
}
layer {
    name: "pool1"
    type: "Pooling"
    bottom: "conv1"
    top: "pool1"
    pooling_param {
        pool: MAX
        kernel_size: 2
        stride: 2
    }
}
layer {
    name: "ip1"
    type: "InnerProduct"
    bottom: "pool1"
    top: "ip1"
    param {
        lr_mult: 1
    }
    param {
        lr_mult: 2
    }
    inner_product_param {
        num_output: 8
        weight_filler {
            type: "gaussian"
            std: 0.005
        }
        bias_filler {
            type: "constant"
            value: 0
        }
    }
}

The model is trained by myself. Used data size is 70000 * 2 * 64 * 64. The network can do nothing but a trial to test why I always get an error like this.

Please pay attention to the last two lines.

I used to think it might be the memory limitation of Pycharm, so I changed the .vmoptions files, no use; I changed the data type from "MemoryData" to "Input", no luck.

So, can anyone give a hint what's going on here? What could I do to get rid of that? Thank you so much!
