Tensorflow:无法创建会话

我运行代码时出错,错误是:

tensorflow.python.framework.errors_impl.InternalError:无法创建会话.

这是我的代码:

# -*- coding: utf-8 -*-

checkpoint='/home/vrview/tensorflow/example/char/data/model/'
MODEL_SAVE_PATH = "/home/vrview/tensorflow/example/char/data/model/"

def getAllImages(folder):
    assert os.path.exists(folder)
    assert os.path.isdir(folder)
    imageList = os.listdir(folder)
    imageList = [os.path.join(folder,item) for item in imageList ]
    num=len(imageList)
    return imageList,num

def get_labei():
    img_dir, num = getAllImages(r"/home/vrview/tensorflow/example/char/data/model/file/")
    for i in range(num):
        image = Image.open(img_dir[i])
        image = image.resize([56, 56])
        image = np.array(image)
        image_array = image

        with tf.Graph().as_default():
            image = tf.cast(image_array, tf.float32)
            image_1 = tf.image.per_image_standardization(image)
            image_2 = tf.reshape(image_1, [1, 56, 56, 3])

            logit = color_inference.inference(image_2)
            y = tf.nn.softmax(logit)
            x = tf.placeholder(tf.float32, shape=[56, 56, 3])

            saver = tf.train.Saver()
            with tf.Session() as sess:
              ckpt = tf.train.get_checkpoint_state(MODEL_SAVE_PATH)
              if ckpt and ckpt.model_checkpoint_path:
                   global_step = ckpt.model_checkpoint_path.split('/')[-1].split('-')[-1]
                   saver.restore(sess, ckpt.model_checkpoint_path)
                   print('Loading success, global_step is %s' % global_step)
                   prediction = sess.run(y)
                   max_index = np.argmax(prediction)
              else:
                   print('No checkpoint file found')

        path='/home/vrview/tensorflow/example/char/data/move_file/'+str(max_index)
        isExists = os.path.exists(path)
        if not isExists :
            os.makedirs(path)
        shutil.copyfile(img_dir[i], path)

def main(argv=None):
    get_labei()

if __name__ == '__main__':
    tf.app.run()

这是我的错误:

也许这并没有回答其背景下的原始问题,但它可能仍然对其他人有所帮助.当我在另一个终端中运行单独的Tensorflow会话时,我收到了上述错误.关闭那个终端让它对我有用.

也许是GPU内存不足？尝试与

export CUDA_VISIBLE_DEVICES=''

还请提供有关您正在使用的平台（操作系统，体系结构）的详细信息。还包括您的TensorFlow版本。

您是否能够从python控制台创建一个简单的会话。像这样：

import tensorflow as tf
hello = tf.constant('hi,tensorflow')
sess = tf.Session()
