Question

我现在正在使用colab复制我的显着性检测！我是学生，所以请理解我的知识还不够，我使用tensorflow找到了代码，因此我试图使用该代码来重现项目。但是，作者说代码是在tensorflow 1.00上编写的，但是如果我只是从colab tensorflow起，我就不知道import tensorflow as tf的版本。我收到错误

'tuple'对象没有属性'gpu_fraction'

和

模块'tensorflow'没有属性'GPUOptions'

这是我的源代码，请查看我的问题

您可以尝试摆脱显式的GPU配置，即打开您的

    gpu_options = tf.GPUOptions(per_process_gpu_memory_fraction=args.gpu_fraction)
    with tf.Session(config=tf.ConfigProto(gpu_options=gpu_options)) as sess:

进入

    with tf.Session() as sess:

'tuple'对象没有属性'gpu_fraction'
