CPU and M1/M2 GPU platform support #71

Closed xiezhq-hermann closed 1 year ago

xiezhq-hermann commented 1 year ago

Minimal modification to extend FlexGen to CPU and M1/M2 GPU platforms. Not fully tested with various offloading settings. @Ying1123 @merrymercy

I tried.

0af9051 *   main Merge branch 'xiezhq-hermann/main'
        |\  
18482fa | * xiezhq-hermann/main update CPU and m1/m2
980ca74 | *   merge latest main
        | |\  
332849a | * | enable CPU and M1/M2 platform
fea8321 * | | origin/main update version
896e1e0 * | | Update README.md
50ae8ad * | | Delete README.md
9d888e5 * | Move apps into flexgen package (#70)

Seems something wrong.

@HIRANO-Satoshi Did you just run the code on your Mac machine? If so, you should add --platform "mps:0" into the command. If you tested it on a machine with NVIDIA GPU, can you try the latest commit (I merged it for you) and rebuild FlexGen? I am not sure what the codes you just ran are.

HIRANO-Satoshi commented 1 year ago

A quick work around.

    def delete_weight(self, j, k):
        if k == 0 and getattr(self, 'weight_home', None):
            for x in self.weight_home[j].pop():

But another one.

I don't have NVIDIA. With --platform cpu, it start working. Thanks much!

Maybe apps/completion.py needs the --platform option.

A proper default without an explicit option would be better.

I'm curious how Apple Neural Engine is fast.
