[22] The second-generation TPUs deliver up to 180 teraflops of performance, and when organized into clusters of 64 TPUs, provide up to 11.5 petaflops. Lets look at how to generate tensors. This is called re-shaping a tensor which we will often do while training deep neural networks. [3] [4] TensorFlow was developed by the Google Brain team for internal Google use in research and production. This lines of code are unrelated to Tensorflow. [35] These loss functions compute the error or difference between a model's output and the expected output (more broadly, the difference between two tensors). [32], In both eager and graph executions, TensorFlow provides an API for distributing computation across multiple devices with various distribution strategies. TensorFlow, an open-source deep learning framework by Google Brain, has evolved from research tool to powerful model builder. When the addition operation runs, it is going to see that it needs to grab the values of the X_1 and X_2 nodes, so we also need to feed in values for X_1 and X_2. It is open source under Apache Open Source license. Watch the video Case studies An entire ecosystem to help you solve challenging, real-world problems with machine learning Easy model building Tensorflow works in a session. It allows you to construct a flowchart of operations that can be performed on these inputs, which goes at one end and comes at the other end as output. We will pass in the X_1 and X_2 nodes to the multiplication node. Tensorflows name is directly derived from its core framework: Tensor. Although it is implemented in C++, TensorFlow can be accessed and controlled by other languages mainly, Python. We should see 4, 10 and 18 for 14, 25 and 36.
