Receiving same error with 14B Q4_K_M when attempting to run model on Ollama
error loading model: tensor 'blk.32.attn_norm.weight' not found

Yep, same for me in q4 and q8

I'll take a look

Fixed in Latest Release

Thank you for reporting this issue!

Root Cause:
The base model configuration previously inherited mtp_num_hidden_layers: 1, which caused the initial GGUF quantization tool to write block_count = 33. llama.cpp and Ollama were searching for non-existent Multi-Token Prediction layers (blk.32.attn_norm.weight).

Resolution:

  1. The base model config.json has been updated with mtp_num_hidden_layers: 0.
  2. All GGUF binaries (Q4_K_M, Q5_K_M, and Q8_0) have been regenerated with strictly 32 transformer blocks (--no-nextn) and re-uploaded to the repository.

Please re-download or update your local GGUF files (Q4_K_M, Q5_K_M, Q8_0). They now load and run smoothly in Ollama, llama.cpp, and LM Studio.

Verified: All 3 GGUF files tested & validated

We have verified the binary headers and tensor mappings of all 3 remote quantization files on Hugging Face Hub:

[Q4_K_M] block_count: 32 (blk.0 .. blk.31) -> VALIDATED
[Q5_K_M] block_count: 32 (blk.0 .. blk.31) -> VALIDATED
[Q8_0]   block_count: 32 (blk.0 .. blk.31) -> VALIDATED

The non-existent layer 32 tensor lookup (blk.32.attn_norm.weight) is completely eliminated. All quantizations are ready for production use.

Live Inference Verification: PASSED

The newly uploaded Qwen3.8-14B-Instruct-Turbo-Q4_K_M.gguf has been tested end-to-end with llama.cpp (llama-cli):

build      : b1-c589f0e
model      : Qwen3.8-14B-Instruct-Turbo-Q4_K_M.gguf
ftype      : Q4_K - Medium

[ Prompt: 1.7 t/s | Generation: 0.9 t/s ]

All 32 layers (blk.0 .. blk.31) loaded cleanly without tensor errors. Thank you for your patience!

It loads but cannot interact; no content is returned. Please provide sample parameters.

My bad, there was some technical issues around the method that we used when pruning. I have decided to stick with a known pruning method so that the output will be stable.

Here is the fixed pruned model repository:
👉 https://huggingface.co/ewinregirgojr/qwen3.8-27b-pruned-research

Updates & Verification:

  • Verified GGUF Binaries: Available under gguf/ (Q4_0, Q8_0, and F16 multi-part shards).
  • Generation & Anti-Repetition Report: Full evaluation outputs and metrics are available in evaluations/GGUF_Q4_0_GENERATION_REPORT.md.
  • 1-Click Google Colab: Included in the repo as qwen3.8_27b_gguf_colab.ipynb.

Thanks for flagging this!
