/workspace/readme.md inside the container for information on getting started and customizing your tensorflow image. you might want to pull in data and model descriptions from locations outside the container for use by tensorflow. to accomplish this, the easiest method is to mount one or more ...
There are three distinct parts that define the TensorFlow workflow, namely preprocessing of data, building the model, and training the model to make predictions. The framework inputs data as a multidimensional array calledtensorsand executes in two different fashions. The primary method is by build...
Note that the alias that you used in the line of code above is sort of a convention - It’s used to ensure that you remain consistent with other developers that are using TensorFlow in data science projects on the one hand, and with open-source TensorFlow projects on the other hand. Get...
