Transformers (Hugging Face)

使用 Hugging Face Transformers 載入 Hub 模型、執行推論、文字生成,以及針對 NLP、視覺、音訊與多模態任務進行 Trainer 微調。適用於 AutoModel、Pipeline、Tokenizer 或 TrainingArguments 等場景,不涵蓋 Transformers 函式庫以外的一般機器學習。

Transformers (Hugging Face) 是什麼?

此技能封裝 Hugging Face Transformers 函式庫(目前測試版本為 5.12.0),讓 AI 代理能夠載入預訓練模型、執行推論與微調。主要提供 Pipeline API 用於快速推論、AutoModel 與 AutoTokenizer 用於自訂載入與前處理、支援多種解碼策略的文字生成、以及使用 Trainer API 進行微調。涵蓋 NLP、電腦視覺、音訊與多模態任務,並支援模型間加速、混合精度與分散式訓練。使用者需注意驗證機制(建議使用 hf auth login 或設定 HF_TOKEN 環境變數),並遵循 Transformers v5 的 PyTorch-only 限制。此技能也提供詳細的參考文件(例如 pipelines.md、models.md、generation.md、training.md 與 tokenizers.md),方便深入了解各元件的最佳實務。

Transformers (Hugging Face) 是做什麼的?

概覽

Hugging Face Transformers 函式庫提供數千個預訓練模型,涵蓋 NLP、電腦視覺、音訊與多模態領域。使用此技能來載入模型、執行推論,以及在自訂資料上進行微調。

安裝

已針對 transformers 5.12.0(2026 年 6 月 PyPI 最新版本)進行測試。需要 Python 3.10+;torch 擴充套件目前需要 PyTorch 2.4+。

uv pip install "transformers[torch]==5.12.0" huggingface_hub==1.19.0 datasets==5.0.0 evaluate==0.4.6 accelerate==1.14.0

針對視覺任務,請額外安裝:

uv pip install timm==1.0.27 pillow==12.2.0

針對音訊任務,請額外安裝:

uv pip install librosa==0.11.0 soundfile==0.14.0

這些版本鎖定是為了確保範例的可重現性。若進行探索性工作,請先查閱 Transformers 與 Hub 的發行說明確認 API 變更後,再放寬版本限制。

檢查已安裝的版本:

import transformers
print(transformers.__version__)

驗證

Hugging Face Hub 上有許多模型需要通過閘門或設為私有。在載入模型前務必先進行驗證。

建議方式: 使用 CLI 登入(令牌會儲存在 ~/.cache/huggingface/token):

hf auth login

Python:

from huggingface_hub import login
login()  # 互動式提示,請勿在腳本中硬編碼令牌

伺服器 / CI: 在環境中設定 HF_TOKEN(切勿將令牌提交至 Git 或 shell 設定檔):

export HF_TOKEN="..."  # 從密碼管理器讀取令牌,而非原始碼

取得令牌:https://huggingface.co/settings/tokens

安全性: 切勿在筆記本、儲存庫或共用設定檔中貼上令牌。建議優先使用 hf auth login,而非在 .bashrc 或 .zshrc 中匯出令牌。

使用權限範圍最小的令牌:read 用於下載私人或需閘道管控的模型,write 僅用於上傳。若長時間運行的環境不希望每次 Hub 請求都發送儲存的令牌,請設定 HF_HUB_DISABLE_IMPLICIT_TOKEN=1,並只在需要驗證的地方傳遞令牌。

Transformers v5

Transformers v5 僅支援 PyTorch(已移除 TensorFlow 與 JAX 後端)。如需從 v4 升級,請參閱 v5 遷移指南。新專案應搭配 transformers 5.x 與 huggingface_hub 1.x。

閘道管控或自訂架構: 在 Hub 上接受模型授權條款後,僅在模型卡需要自訂程式碼且您已審查過的情況下,使用 trust_remote_code=True 載入。

快取位置: 設定 HF_HOME 可調整所有 Hugging Face 快取的路徑,或設定 HF_HUB_CACHE 僅調整 Hub 檔案快取。只有在所需模型快照已快取完畢後,才使用 HF_HUB_OFFLINE=1。

快速開始

使用 Pipeline API 快速進行推論,無需手動設定:

from transformers import pipeline

# 文字生成(因果語言模型建議使用 max_new_tokens)
generator = pipeline("text-generation", model="Qwen/Qwen2.5-1.5B")
result = generator("The future of AI is", max_new_tokens=50)

# 文字分類
classifier = pipeline("text-classification")
result = classifier("This movie was excellent!")

# 問答
qa = pipeline("question-answering")
result = qa(question="What is AI?", context="AI is artificial intelligence...")

核心功能

1. 使用 Pipeline 進行快速推論

用於簡化且最佳化的多種任務推論。支援文字生成、分類、命名實體辨識、問答、摘要、翻譯、影像分類、物件偵測、音訊分類等。

使用時機: 快速原型開發、簡單的推論任務、無需自訂前處理。

請參閱 references/pipelines.md 以了解完整的任務支援與最佳化方式。

2. 模型載入與管理

載入預訓練模型,並可精細控制設定、裝置配置與精度。

使用時機: 自訂模型初始化、進階裝置管理、模型檢查。

請參閱 references/models.md 以了解載入模式與最佳實務。

3. 文字生成

使用多種解碼策略(貪婪、Beam Search、採樣)與控制參數(溫度、top-k、top-p)來生成文字。

使用時機: 創意文字生成、程式碼生成、對話式 AI、文字補全。

請參閱 references/generation.md 以了解生成策略與參數。

4. 訓練與微調

使用 Trainer API 在自訂資料集上微調預訓練模型,支援自動混合精度、分散式訓練與記錄。

使用時機: 任務特定模型調整、領域適應、提升模型效能。

請參閱 references/training.md 以了解訓練流程與最佳實務。

5. 分詞

將文字轉換為 Token 與 Token ID,作為模型輸入,並處理填充、截斷與特殊 Token。

使用時機: 自訂前處理流程、理解模型輸入、批次處理。

請參閱 references/tokenizers.md 以了解分詞細節。

常見模式

模式 1:簡單推論

針對直接任務,使用 Pipeline:

pipe = pipeline("task-name", model="model-id")
output = pipe(input_data)

模式 2:自訂模型使用

需要進階控制時,分別載入模型與分詞器:

from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("model-id")
model = AutoModelForCausalLM.from_pretrained("model-id", device_map="auto")

inputs = tokenizer("text", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=100)
result = tokenizer.decode(outputs[0])

模式 3:微調

針對任務適應,使用 Trainer:

from transformers import Trainer, TrainingArguments

training_args = TrainingArguments(
    output_dir="./results",
    num_train_epochs=3,
    per_device_train_batch_size=8,
)

trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=train_dataset,
)

trainer.train()

arbor

Autonomously improve a real artifact (code, training recipe, agent harness, data pipeline, prompt) against an objective and an evaluator, using Hypothesis Tree Refinement (HTR) from the Arbor paper. Use this whenever someone wants to iteratively optimize something over many experiments without overfitting — e.g.

biopython

Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.

bioservices

Unified Python interface to 40+ bioinformatics services. Use when querying multiple databases (UniProt, KEGG, ChEMBL, Reactome) in a single workflow with consistent API. Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.

bulk-rnaseq

End-to-end bulk RNA-seq orchestrator — takes raw FASTQ reads through QC and trimming (FastQC, fastp/Trim Galore), alignment and quantification (STAR, Salmon, featureCounts), assembles a gene-level counts matrix, then hands off to differential expression (pydeseq2), pathway/GSEA enrichment (pathway-enrichment), and publication figures (scientific-visualization). Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g.

cellxgene-census

Query the CZ CELLxGENE Census programmatically for versioned public single-cell and spatial transcriptomics data. Use when you need population-scale cell metadata, gene expression slices, Census summary counts, source H5AD URIs/downloads, embeddings, spatial Census data, or reference atlas comparisons across organisms, tissues, diseases, assays, and cell types. For analyzing your own local single-cell data use scanpy, anndata, or scvi-tools.

cirq

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.

citation-management

Comprehensive citation management for academic research. Search OpenAlex, PubMed, and Google Scholar for papers, extract accurate metadata, validate citations, and generate properly formatted BibTeX entries. This skill should be used when you need to find papers, verify citation information, convert DOIs to BibTeX, or ensure reference accuracy in scientific writing.

clinical-decision-support

Prepare and validate research-only clinical decision-support evaluation, evidence-profile, cohort, survival, biomarker/model, privacy, and governance artifacts. Use for aggregate or synthetic research documentation and traceability—not patient care or live clinical operation.

clinical-reports

Create safety-bounded draft structures and run local deterministic checks for clinical case, diagnostic, trial, safety, and aggregate research reports. Use only with synthetic, de-identified, or aggregate inputs and verified source-fact manifests; every output requires qualified review.
