具有多个元素的数组的真值不明确

使用此链接进行双线性插值 http://cv-tricks.com/image-segmentation/transpose-convolution-in-tensorflow/

我正在尝试使用虚拟矩阵来获取一些结果，即在我的代码中将维度4的filter_shape命名为张量。但这给了我一个错误。谁能帮我举一个虚拟的例子来运行此双线性插值代码？

import tensorflow as tf
import numpy as np
#tensor=np.zeros((2,2,3,3))
tensor=np.random.random((2,2,3,3))
print(tensor)
def get_bilinear_filter(filter_shape, upscale_factor):
    ##filter_shape is [width, height, num_in_channels, num_out_channels]
    kernel_size = filter_shape[1]
    ### Centre location of the filter for which value is calculated
    if kernel_size % 2 == 1:
        centre_location = upscale_factor - 1
    else:
        centre_location = upscale_factor - 0.5

    bilinear = np.zeros([filter_shape[0], filter_shape[1]])
    for x in range(filter_shape[0]):
        for y in range(filter_shape[1]):
            ##Interpolation Calculation
            value = (1 - abs((x - centre_location)/ upscale_factor)) * (1 - abs((y - centre_location)/ upscale_factor))
            bilinear[x, y] = value
    weights = np.zeros(filter_shape)
    print(weights)
    for i in range(filter_shape[2]):
        weights[:, :, i, i] = bilinear
    init = tf.constant_initializer(value=weights,
                                   dtype=tf.float32)

    bilinear_weights = tf.get_variable(name="decon_bilinear_filter", initializer=init,
                           shape=weights.shape)
    print(bilinear_weights)



get_bilinear_filter(tensor,3)
