Since the weights add up to one, it’s exactly equivalent to doing a weighted average of the three color channels. Here’s the result: The first image is a bit darker, and the edges and shadows are bolder. The second image is lighter and brighter, and the dark lines aren’t quite ...
I didn't manage to 100% convince myself that all the Target changes produce visibly equivalent code, so I'm pretty much banking on the tests there. crates/accelerate/src/error_map.rs Show resolved crates/accelerate/src/euler_one_qubit_decomposer.rs Outdated @@ -109,11 +110,13 @@ imp...

In this tutorial, we will learn how to add a row to a matrix in numpy.Use the numpy.vstack() Function to Add a Row to a Matrix in NumPyThe vstack() function stacks arrays vertically. Stacking two 2D arrays vertically is equivalent to adding rows to a matrix....
This is equivalent to sort_keys=True in the standard library.This can be used to ensure the order is deterministic for hashing or tests. It has a substantial performance penalty and is not recommended in general.>>> import orjson >>> orjson.dumps({"b": 1, "c": 2, "a": 3}) b'...
In version 2 this was required to serialize uuid.UUID instances. For more, see UUID.OPT_SORT_KEYSSerialize dict keys in sorted order. The default is to serialize in an unspecified order. This is equivalent to sort_keys=True in the standard library....
This is equivalent to indent=2 in the standard library. Pretty printing is slower and the output larger. orjson is the fastest compared library at pretty printing and has much less of a slowdown to pretty print than the standard library does. This option is compatible with all other options....
