Libraries

How to use hmellor/tiny-random-DeepseekV2ForCausalLM with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="hmellor/tiny-random-DeepseekV2ForCausalLM")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("hmellor/tiny-random-DeepseekV2ForCausalLM")
model = AutoModelForCausalLM.from_pretrained("hmellor/tiny-random-DeepseekV2ForCausalLM", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

	# tiny-random-DeepseekV2ForCausalLM

	Randomly initialised `DeepseekV2ForCausalLM` for testing MLA (multi-head latent
	attention) and MoE code paths without loading a 29 GiB checkpoint. Used by
	vLLM's `tests/models/transformers/test_backend.py::test_mla`.

	The attention head dimensions are copied verbatim from
	[deepseek-ai/DeepSeek-V2-Lite-Chat](https://huggingface.co/deepseek-ai/DeepSeek-V2-Lite-Chat)
	so that `kv_lora_rank + qk_rope_head_dim == 576`, the latent head size every MLA
	kernel is built around. Only the width, depth and expert counts are shrunk.

	\| \| DeepSeek-V2-Lite-Chat \| this model \|
	\| ------------------- \| --------------------- \| ---------- \|
	\| `kv_lora_rank` \| 512 \| 512 \|
	\| `qk_nope_head_dim` \| 128 \| 128 \|
	\| `qk_rope_head_dim` \| 64 \| 64 \|
	\| `v_head_dim` \| 128 \| 128 \|
	\| `hidden_size` \| 2048 \| 256 \|
	\| `num_hidden_layers` \| 27 \| 4 \|
	\| `num_attention_heads` \| 16 \| 4 \|
	\| `n_routed_experts` \| 64 \| 8 \|
	\| `n_shared_experts` \| 2 \| 2 \|
	\| parameters \| 15.7B \| 59.8M \|

	Layer 0 is dense and the rest are MoE (`first_k_dense_replace=1`), matching the
	real model. The tokenizer is DeepSeek-V2-Lite-Chat's, unmodified.

	The weights are random, so the outputs are meaningless. This is only useful for
	checking that two implementations agree with each other.
