List of list of module names to quantize in the specified block. This argument is useful to exclude certain linear modules from being quantized.
The block to quantize can be specified by setting <code>block_name_to_quantize</code>. We will quantize each list sequentially. If not set, we will quantize all linear layers.
Example: <code>modules_in_block_to_quantize =[[&quot;self_attn.k_proj&quot;, &quot;self_attn.v_proj&quot;, &quot;self_attn.q_proj&quot;], [&quot;self_attn.o_proj&quot;]]</code>.
In this example, we will first quantize the q,k,v layers simultaneously since they are independent.
Then, we will quantize <code>self_attn.o_proj</code> layer with the q,k,v layers quantized. This way, we will get
better results since it reflects the real input <code>self_attn.o_proj</code> will get when the model is quantized.<!-- HTML_TAG_END --> </span></span> </li></ul> </div></div> <p data-svelte-h="svelte-i3efvr">This is a wrapper class about all possible attributes and features that you can play with a model that has been

これは、<code>LLM.int8()</code>論文で説明されている外れ値検出の外れ値しきい値に対応します。このしきい値を超える隠し状態の値は外れ値とみなされ、それらの値に対する操作は fp16 で実行されます。通常、値は正規分布します。つまり、ほとんどの値は [-3.5, 3.5] の範囲内にありますが、大規模なモデルでは大きく異なる分布を示す例外的な系統的外れ値がいくつかあります。これらの外れ値は、多くの場合 [-60, -6] または [6, 60] の範囲内にあります。 Int8 量子化は、大きさが 5 程度までの値ではうまく機能しますが、それを超えると、パフォーマンスが大幅に低下します。適切なデフォルトのしきい値は 6 ですが、より不安定なモデル (小規模なモデル、微調整) では、より低いしきい値が必要になる場合があります。
この引数は、モデルの推論速度に影響を与える可能性があります。このパラメータを試してみて、ユースケースに最適なパラメータを見つけることをお勧めします。</p> <div class="code-block relative"><div class="absolute top-2.5 right-4"><button class="inline-flex items-center relative text-sm focus:text-green-500 cursor-pointer focus:outline-none transition duration-200 ease-in-out opacity-0 mx-0.5 text-gray-600 " title="code excerpt" type="button"><svg class="" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" fill="currentColor" focusable="false" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 32 32"><path d="M28,10V28H10V10H28m0-2H10a2,2,0,0,0-2,2V28a2,2,0,0,0,2,2H28a2,2,0,0,0,2-2V10a2,2,0,0,0-2-2Z" transform="translate(0)"></path><path d="M4,18H2V4A2,2,0,0,1,4,2H18V4H4Z" transform="translate(0)"></path><rect fill="none" width="32" height="32"></rect></svg> <div class="absolute pointer-events-none transition-opacity bg-black text-white py-1 px-2 leading-tight rounded font-normal shadow left-1/2 top-full transform -translate-x-1/2 translate-y-2 opacity-0"><div class="absolute bottom-full left-1/2 transform -translate-x-1/2 w-0 h-0 border-black border-4 border-t-0" style="border-left-color: transparent; border-right-color: transparent; "></div> Copied</div></button></div> <pre class=""><!-- HTML_TAG_START --><span class="hljs-keyword">from</span> transformers <span class="hljs-keyword">import</span> AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig

This corresponds to the outlier threshold for outlier detection as described in <code>LLM.int8() : 8-bit Matrix Multiplication for Transformers at Scale</code> paper: <a href="https://arxiv.org/abs/2208.07339" rel="nofollow">https://arxiv.org/abs/2208.07339</a> Any hidden states value
that is above this threshold will be considered an outlier and the operation on those values will be done
in fp16. Values are usually normally distributed, that is, most values are in the range [-3.5, 3.5], but
there are some exceptional systematic outliers that are very differently distributed for large models.
These outliers are often in the interval [-60, -6] or [6, 60]. Int8 quantization works well for values of
magnitude ~5, but beyond that, there is a significant performance penalty. A good default threshold is 6,
but a lower threshold might be needed for more unstable models (small models, fine-tuning).<!-- HTML_TAG_END --> </span></span> </li><li class="text-base !pl-4 my-3 rounded "><span class="group flex space-x-1.5 items-start"><a id="transformers.BitsAndBytesConfig.llm_int8_skip_modules" class="header-link block pr-0.5 text-lg no-hover:hidden with-hover:absolute with-hover:p-1.5 with-hover:opacity-0 with-hover:group-hover:opacity-100 with-hover:right-full" href="#transformers.BitsAndBytesConfig.llm_int8_skip_modules"><span><svg class="text-smd" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" aria-hidden="true" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 256 256"><path d="M167.594 88.393a8.001 8.001 0 0 1 0 11.314l-67.882 67.882a8 8 0 1 1-11.314-11.315l67.882-67.881a8.003 8.003 0 0 1 11.314 0zm-28.287 84.86l-28.284 28.284a40 40 0 0 1-56.567-56.567l28.284-28.284a8 8 0 0 0-11.315-11.315l-28.284 28.284a56 56 0 0 0 79.196 79.197l28.285-28.285a8 8 0 1 0-11.315-11.314zM212.852 43.14a56.002 56.002 0 0 0-79.196 0l-28.284 28.284a8 8 0 1 0 11.314 11.314l28.284-28.284a40 40 0 0 1 56.568 56.567l-28.285 28.285a8 8 0 0 0 11.315 11.314l28.284-28.284a56.065 56.065 0 0 0 0-79.196z" fill="currentColor"></path></svg></span></a> <span><!-- HTML_TAG_START --><strong>llm_int8_skip_modules</strong> (<code>List[str]</code>, <em>optional</em>) &#x2014;
