We present a simple and computationally efficient quantization scheme that enables us to reduce the resolution of theparametersof a neural network from 32-bit floating point values to 8-bit integer values. The proposed quantization scheme leads to significant memory savings and enables the use of op...
到这位置,只是介绍了8bit量化在TF上的实现原理和方式。而现在学术界对于量化有很多新的研究包括:quantized training, non-linear quantization, binary quantization, networks without multipliers等等,在不久的将来希望能够出现无损且高效的量化手段,这将极大收益训练和推测。

@文心快码BaiduComateusing `bitsandbytes` 8-bit quantization requires accelerate: `pip install ac 文心快码BaiduComate 看来你打算使用bitsandbytes库进行8-bit量化,并且注意到了需要安装accelerate库。下面我会按照你的提示逐一解答你的问题: 确认用户意图安装accelerate库: 是的,为了使用bitsandbytes库的8-bit量化...
高通的一篇论文“FP8 Quantization: The Power of the Exponent”对FP8量化进行了深入探讨。论文从FP8的基本概念、实现方法和效果评估三个方面入手。首先，回顾了浮点数表示方式，并解释了FP8的量化机制。论文展示FP8量化对于不同分布的优越性，通过比较与int8量化的效果，显示在接近0值的数据点上，FP8量化...
Pytorch convert from jax likely will open this model to be more accessible to 8-bit quantization. Which I think has been done. https://huggingface.co/hpcai-tech/grok-1 and https://github.com/hpcaitech/ColossalAI/tree/main/examples/language/grok-1 for example. This is just for the base...
Post training quantization 一般来说,冻好的模型中典型的conv层包含以下参数: weights tensor input tensor forward pass operator output tensor 对输出来说,大部分层输出的值都只会落在一个很窄的区间内,因此对output进行量化就需要利用在在训练的时候统计大部分输入得到的输出来进行统计确定合适的最大和最小值。
