Python comes with a lot of batteries included. You can writehigh-quality, efficient code, but it’s hard to beat the underlying libraries. These have been optimized and are tested rigorously (like your code, no doubt). Read thelistof the built-ins, and check if you’re duplicating any of this functionality in your code. See more When you’re working in Python, loops are common. You’ve probably come across list comprehensions before. They’re a concise and speedy way to create new lists. For example, let’s say you wanted to find the cubes of all … See more Python 2 used the functions range() and xrange() to iterate over loops. The first of these functions stored all the numbers in the range in memory and got linearly large as the range did. The … See more When you startedlearning Python, you probably got advice to import all the modules you’re using at the start of your program. Maybe you still sort these alphabetically. This approach makes it easier to keep track of … See more The previous tip hints at a general pattern for optimization—namely, that it’s better to use generators where possible. These allow you to return an … See more WebJan 29, 2024 · Here’s a simple end-to-end example. First, we define a model-building function. It takes an hp argument from which you can sample hyperparameters, such as hp.Int('units', min_value=32, max_value=512, step=32) (an integer from a certain range). Notice how the hyperparameters can be defined inline with the model-building code.

Where’s the 10? That’s where it gets a bit tricky. You see 1 is our start but the very definition of stop is the integer before the sequence is to end. WebJun 7, 2015 · We developed the Python GEKKO package for solving similar problems. We're also working on machine learning functions that may be able to combine a convolutional neural network with this constrained mixed-integer problem as a single optimization.
