introduce build.go for controlling distribution builds

This commit aims to provide the Ollama maintainers with maximum control of the distribution build process by creating a cross-platform shim. Currently, we have no flexibility, or control of the process (pre and post) or even the quality of the build. By introducing a shim, and propagating it out to Homebrew, et al., we can soon after ensure that the build process is consistent, and reliable. This also happens to remove the requirement for go generate and the build tag hacks, but it does still support go generate in the flow, at least until we can remove it after the major distribution use the new build process. About the script: Beyond giving the Ollama maintainers drastically more control over the build process, the script also provides a few other benefits: - It is cross-platform, and can be run on any platform that supports Go (a hard requirement for building Ollama anyway). - It can can check for correct versions of cmake, and other dependencies before starting the build process, and provide helpful error messages to the user if they are not met. - It can be used to build the distribution for any platform, architecture, or build type (debug, release, etc.) with a single command. Currently, it is two commands. - It can skip parts of the build process if they are already done, such as build the C dependencies. Of course there is a -f flag to force rebuild. - So much more!

Blake Mizerany	7893ccb68c	introduce build.go for controlling distribution builds This commit aims to provide the Ollama maintainers with maximum control of the distribution build process by creating a cross-platform shim. Currently, we have no flexibility, or control of the process (pre and post) or even the quality of the build. By introducing a shim, and propagating it out to Homebrew, et al., we can soon after ensure that the build process is consistent, and reliable. This also happens to remove the requirement for go generate and the build tag hacks, but it does still support go generate in the flow, at least until we can remove it after the major distribution use the new build process. About the script: Beyond giving the Ollama maintainers drastically more control over the build process, the script also provides a few other benefits: - It is cross-platform, and can be run on any platform that supports Go (a hard requirement for building Ollama anyway). - It can can check for correct versions of cmake, and other dependencies before starting the build process, and provide helpful error messages to the user if they are not met. - It can be used to build the distribution for any platform, architecture, or build type (debug, release, etc.) with a single command. Currently, it is two commands. - It can skip parts of the build process if they are already done, such as build the C dependencies. Of course there is a -f flag to force rebuild. - So much more!	2024-06-30 22:18:45 -07:00

Blake Mizerany	cb42e607c5	llm: speed up gguf decoding by a lot (#5246 ) Previously, some costly things were causing the loading of GGUF files and their metadata and tensor information to be VERY slow: * Too many allocations when decoding strings * Hitting disk for each read of each key and value, resulting in a not-okay amount of syscalls/disk I/O. The show API is now down to 33ms from 800ms+ for llama3 on a macbook pro m3. This commit also prevents collecting large arrays of values when decoding GGUFs (if desired). When such keys are encountered, their values are null, and are encoded as such in JSON. Also, this fixes a broken test that was not encoding valid GGUF.	2024-06-24 21:47:52 -07:00
Blake Mizerany	2aa91a937b	cmd: defer stating model info until necessary (#5248 ) This commit changes the 'ollama run' command to defer fetching model information until it really needs it. That is, when in interactive mode. It also removes one such case where the model information is fetch in duplicate, just before calling generateInteractive and then again, first thing, in generateInteractive. This positively impacts the performance of the command: ; time ./before run llama3 'hi' Hi! It's nice to meet you.
