> pip install tf-nightly-2.0-preview # tf-nightly-gpu-2.0-preview for GPU version 快速验证一下安装是否成功: >>> import tensorflow as tf >>> print(tf.__version__)1.13.0-dev20190117 >>> print(tf.executing_eagerly()) True 显示的是 1.13.x 版本?不用担心,这是因为它还是早期预览版。这里需...
而且,只需要多加一行代码就可以启用静态图执行。 with tf.Graph().as_default(): print(tf.executing_eagerly()) # False model = Model(num_actions=env.action_space.n) agent = A2CAgent(model) rewards_history = agent.train(env) print("Finished training, testing...") print("%d out of 200" ...
Contributor nfelt commented Jun 15, 2018 You'll want to install a more recent version of tensorflow-gpu than 1.5.0: https://pypi.org/project/tensorflow-gpu/#history I don't know what tensorboard_logger is - that's not a module that we provide, so you'd have to ask whoever provides...
谷歌于2019年3月6日和7日在其年度TensorFlow开发者峰会上发布了最新版本的TensorFlow机器学习框架。这一新版本使用TensorFlow的方式进行了重大改进。TensorFlow拥有最大的开发者社区之一,从机器学习库到完善的机器学习生态系统已经走过了漫长的道路。
rewards_history = agent.train(env)print("Finished training, testing...")print("%d out of 200"% agent.test(env))# 200 out of 200 有一点需要注意,在静态图形执行期间,我们不能只有Tensors,这就是为什么我们在模型定义期间需要使用CategoricalDistribution的技巧。事实上,当我在寻找一种在静态模式下执行的...
