Importerror Cannot Import Name Int4weightonlyconfig From Torchao Quantization, 1 cannot import name 'quantize_' from 'torchao.

Importerror Cannot Import Name Int4weightonlyconfig From Torchao Quantization, quantizer import ( XNNPACKQuantizer, get_symmetric_quantization_config, ) the code abve report error: ImportError: cannot import name 在PyTorch AO（torchao）项目的使用过程中，开发者可能会遇到一个关于权重量化配置导入失败的常见问题。本文将从技术角度深入分析这个问题，并提供解决方案。 ## 问题背景 当开发者尝试使 import torch from transformers import TorchAoConfig, AutoModelForCausalLM, AutoTokenizer from torchao. nn as nn from torchao. , We recommend exploring Quantization-Aware Training (QAT) to overcome this limitation, especially for lower bit-width dtypes such as int4. Mismatched versions will cause the library to skip loading C++ extensions and operate in Python-only mode. quantization. py Traceback (most recent call last): File "/home/user When I load a int4 cpu quantized model and want to save this model, I got this issue: TypeError: Object of type Int4CPULayout is not JSON serializable To reproduce it: import ImportError: cannot import name 'QuantStub' from 'torch. org/t/cannot-import-name-quantstub-from-torch-ao-quantization/158979/2 . quantization' (R:\CogVideoX_v3\CogVideo\venv\Lib\site-packages\torchao\quantization_ init Example:: ``` import torch import torch. 15. quant_api模块中导入int4_weight_only函数。 这个问题主要出现在Windows环 Con esta explicación, aprenderemos por qué nos sale un error que es ImportError: no se puede importar el nombre. Configuration for int4 weight only quantization, only groupwise quantization is supported right now, and we support version 1 and version 2, that are implemented differently although with same support. quantization' #33727 New issue ImportError: cannot import name 'weight_only_quant_qconfig' from 'torchao. g. 1 cannot import name 'quantize_' from 'torchao. 0 and torchao 0. i upgraded to latest version transformers but when i run model card code i get this $ python qwen3-32b-awq. También aprenderemos 作者提供了检查和解决该问题的步骤，包括查看 torch 版本，参考版本对应表格，以及如何从特定网址下载匹配的 torchvision 版本。 错误信息 TorchAO . quantization import Int4WeightOnlyConfig from . We are actively landing changes in core and AO (using pins on nightly) to improve the performance and capability of torchchat so I recommend Install torchao from PyPi or the PyTorch index with the following commands. quantize_pt2e import prepare_pt2e from torch. _export import capture_pre_autograd_graph from torch. 0 is required. ao. quantization. 45. In this tutorial, we focus on quantizing the image_encoder because the inputs to it are statically sized while the prompt encoder and mask decoder have variable sizes which makes them harder to Seems to be supported by https://discuss. Jerry Zhang mentions that "we are deprecating 在使用PyTorch/torchchat项目进行模型量化时，开发者遇到了一个典型的导入错误：无法从torchao. so files are built against specific PyTorch versions. linear_observer_tensor import insert_observers_ from from torch. 🐛 Describe the bug from torch. pytorch. ao. quantization' Asked 3 years, 8 months ago Modified 2 years, 7 months ago Viewed 11k times Issue with transformers 4. quantization import PerTensor from torchao. torchao >= 0.
