TypeError
这是我的代码:
import scipy.io as sio
import numpy as np
import theano.tensor as T
from theano import shared
from convnet3d import ConvLayer, NormLayer, PoolLayer, RectLayer
from mlp import LogRegr, HiddenLayer, DropoutLayer
from activations import relu, tanh, sigmoid, softplus
dataReadyForCNN = sio.loadmat("DataReadyForCNN.mat")
xTrain = dataReadyForCNN["xTrain"]
# xTrain = np.random.rand(10, 1, 5, 6, 2).astype('float64')
xTrain.shape
dtensor5 = T.TensorType('float64', (False,)*5)
x = dtensor5('x') # the input data
yCond = T.ivector()
# input = (nImages, nChannel(nFeatureMaps), nDim1, nDim2, nDim3)
kernel_shape = (5,6,2)
fMRI_shape = (51, 61, 23)
n_in_maps = 1 # channel
n_out_maps = 5 # num of feature maps, aka the depth of the neurons
num_pic = 2592
layer1_input = x
# layer1_input.eval({x:xTrain}).shape
# layer1_input.shape.eval({x:numpy.zeros((2592, 1, 51, 61, 23))})
convLayer1 = ConvLayer(layer1_input, n_in_maps, n_out_maps, kernel_shape, fMRI_shape,
num_pic, tanh)
print convLayer1.output.shape.eval({x:xTrain})
这真的很奇怪,因为错误没有在 Jupyter 中引发(但运行需要很长时间,最后内核关闭,我真的不知道为什么),但是当我将它移到 shell 并运行 @ 987654323@错误被抛出。
