CUDNN_STATUS_NOT_INITIALIZED

自从装好tensorflow-gpu 之后其实一直没怎么用，今天跑代码的时候才发现安装的有问题：

测试代码如下：

from sklearn.datasets import load_sample_image
import matplotlib.pyplot as plt
import numpy as np
import tensorflow as tf

if __name__ == '__main__':
    # Load sample images
    china = load_sample_image("china.jpg")
    flower = load_sample_image("flower.jpg")
    dataset = np.array([china, flower], dtype=np.float32)
    batch_size, height, width, channels = dataset.shape
    # Create 2 filters
    filters = np.zeros(shape=(7, 7, channels, 2), dtype=np.float32)
    filters[:, 3, :, 0] = 1 # vertical line
    filters[3, :, :, 1] = 1 # horizontal line
    # Create a graph with input X plus a convolutional layer applying the 2 filters
    X = tf.placeholder(tf.float32, shape=(None, height, width, channels))
    convolution = tf.nn.conv2d(X, filters, strides=[1,2,2,1], padding="SAME")
    with tf.Session() as sess:
        output = sess.run(convolution, feed_dict={X: dataset})
    plt.imshow(output[0, :, :, 1], cmap="gray") # plot 1st image's 2nd feature map
    plt.show()

虽然代码比较简单，但是运行却出现了问题，报了一大堆错误：

网上搜索了一下解决方案，但是并不是很好用。最后尝试了如下方法
