5.1 Bytes转Bits 在Python中,将字节转换为位通常涉及到将每个字节转换为8位的二进制表示。以下是一个简单的函数,用于将字节数据转换为位字符串: def bytes_to_bits(byte_data):"""将字节数据转换为位字符串"""return ''.join(format(byte, '08b') for byte in byte_data) 使用方法: data_bytes = b'he...
>>> bytes((1,2,3)) b'\x01\x02\x03' >>> bytes("hello", "ascii") b'hello' The bytearray object serves the same purpose as bytes but is mutable, allowing elements in the array to be modified. It has the constructor bytearray(). >>> x = bytearray("hello.", "ascii") >>...

总之,您需要确保transformers和bitsandbytes之间的配合无缝无误,以避免类似get_loading_attributes方法缺失引发的加载失败问题。 这python项目的依赖管理似乎不如主流maven项目来的稳定,这种版本依赖关系应该是requirements.txt约定好。 不使用Int4版本 model_dir = "/home/yeqiang/Downloads/ai/Qwen-VL-Chat" ...

1. Bits-and-Bytes量化 Bits-and-Bytes是一个功能多样的模型量化库,主要聚焦于4位和8位格式。与GPTQ等方法不同,它在推理过程中进行量化时,无需校准数据集。该库支持的8位量化,对于在资源有限的硬件上运行大型模型非常实用。而在4位量化方面,它引入了FP4和NF4等特定格式,针对微调和推理任务都进行了优化。不过,...
