新版本亮点包括如下: oneDNN 的性能改进; DTensor 的发布,这是一种新 API,可用于从数据并行无缝迁移到模型并行; 对核心库进行了改进,包括 Eigen、tf.function 统一以及对...Windows 的 WSL2 的新支持; 还为 tf.function retracing 和 Keras 优化器发布了新的实验性 API。 ...dtensor_ml_tutorial 将 DTenso...
For example the default activation function tf.keras.layers.Dense is "relu", but for tf.layers.Dense it is "linear". Caveat emptor! EDIT: Nevermind, I must have hallucinated this difference... Contributor bhack commented Aug 23, 2018 I see from the slide number 5 that: Keras is the ...
