Same here, Windows with 4080.

May be related, I'm getting an error with llama.cpp. I'm using mixtral-8x7b-instruct-v0.1.Q6_K.gguf:

llama.cpp

error loading model: create_tensor: tensor 'blk.0.ffn_gate.weight' not found
llama_load_model_from_file: failed to load model
llama_init_from_gpt_params: error: failed to load model './models/mixtral-8x7b-instruct-v0.1.Q6_K.gguf'

You currently need a special build of llama.cpp (branch mixtral) as the support has not been merged into master yet.

I'm getting an error in Text Generation WebUI:

shared.model, shared.tokenizer = load_model(shared.model_name, loader)

I'll see if I can try something with llama.cpp as mentioned above

I built that specific "mixtral" branch (https://github.com/ggerganov/llama.cpp/tree/mixtral), but I've never used any llamacpp that I built myself with TextGenWebUi, are there any steps or docs?

#First go to your textwebui directory
cd yourdirectoryhere

#Activate the conda env
cp ./start_linux.sh activate_conda.sh # also remove the last line of activate_conda.sh
chmod +x activate_conda.sh
./activate_conda.sh

#Go to the repository setting and clone llama-cpp-python
cd repositories/
git clone https://github.com/abetlen/llama-cpp-python
cd llama-cpp-python

#Delete the normal usual lama.cpp and get the new one
cd vendor
rm -R rm -R llama.cpp/
git clone https://github.com/ggerganov/llama.cpp.git
cd llama.cpp
git checkout mixtral

#Build the good stuff, check here for more details: https://github.com/ggerganov/llama.cpp
cd ../../
#I assume you use cuda here, check the link otherwise
make LLAMA_OPENBLAS=1

#Uninstall the old lama.cpp
pip list # look for lama.cpp or something similar
pip uninstall lama.cpporsomethingsimilar

#Install the new one
pip install .

And you should be good ! Not near my computer so I'm writing this from memory. Don't hesitate to correct this and I will edit.

Downloaded and installed the new LM Studio this morning which has experimental support for this model. LM Studio no longer gives me that error immediately, but I still get a "failed to load model" error after it tries to load for some time.

working for me with LMStudio v0.2.9. So far, I'm really impressed with this one.
