From d0d5de42e5a65865b5fddb6f5c785083539b74c3 Mon Sep 17 00:00:00 2001 From: Pierrick Hymbert Date: Tue, 19 Mar 2024 12:05:44 +0100 Subject: [PATCH] gguf-split: split and merge gguf per batch of tensors (#6135) * gguf-split: split and merge gguf files per tensor * gguf-split: build with make toolchain * gguf-split: rename `--split-tensors-size` to `--split-max-tensors`.
