ggml_new_tensor_impl: not enough space in the context's memory pool

[NotNite]

Heya! Friend showed this to me and I'm trying to get it to work myself on Windows 10. I've applied the changes as seen in #22 to get it to build (more specifically, I pulled in the new commits from etra0's fork, but the actual executable fails to run - printing this before segfaulting:

ggml_new_tensor_impl: not enough space in the context's memory pool (needed 458853944, available 454395136)
ggml_new_tensor_impl: not enough space in the context's memory pool (needed 458870468, available 454395136)

I'm trying to use 7B on an i9-13900K (and I have about 30 gigs of memory free right now), and I've verified my hashes with a friend. Any ideas? Thanks!

Tried out #31 - it, uh, got farther: GGML_ASSERT: D:\code\c++\llama.cpp\ggml.c:9349: false

ok I did an upsie in that PR, initializing it that way apparently didn't zero'ed out the rest of the fields. I updated the branch, please test it again now!

It started to expand the prompt, but with seemingly garbage data: Building a website can be done in 10 simple steps: ╨Ñ╤Ç╨╛╨╜╨╛╨╗╨╛╨│╨╕╤ÿ╨

Should be good on latest master - reopen if issue persists.
Make sure to rebuild and regen the models after updating

Hey i was trying to run this on a RHEL 8 server with 32 cpu cores. and i am getting the same error. On my second query.

I am using GPT4All-J v1.3-groovy.

Hi @ggerganov @gjmulder I would appreciate some direction for this pls.

Getting the same issue on Apple M1 Pro with 16GB RAM when trying the example from:

Oh hey, exact same error:

[omarelanis]

Same issue here, tried a combination of settings but just keep getting the memory error even though both RAM and GPU RAM are less than 50% utilization.

I had to follow the guide here to build llama-cpp with GPU support as it wasn't working previously, but even before that it was giving the same error (side note GPU support natively does work in oobabooga windows!?):
abetlen/llama-cpp-python#182

Anyone have any ideas?

Same here... any solutions already???

[sherrmann]

Solved this by going back to llama-cpp-python version 0.1.74
