Numpy Tobytes Without Copy, tobytes # method ndarray. tobytes(order='C') ¶ Construct Python bytes containing the raw data bytes in the array. In a strided scheme, the N-dimensional index (n 0, n 1,, n N 1) corresponds to the offset (in bytes): n o f f s e t = ∑ k = 0 N 1 s k n k from the beginning of the memory block associated with the array. I want to convert this numpy array to bytes but without any copying due to memory constraints. Jan 27, 2026 · If you handle NumPy arrays in anything beyond notebooks—networking, storage, interoperability with C/C++ or Rust, GPU uploads, hashing, or caching—you’ll eventually need ndarray. It also improves free threading and brings sorting into compliance with the array-api standard with the addition of descending sorts. 15 will be supported when it is released. On my machine, the copy succeed to reach 66 GiB/s in the L3 cache which is very good for a sequential python function. Inverse of this operation, construct a 1-dimensional array from Python bytes.
