可以在不加载整个文件的情况下查看文件的信息或者只加载文件中的部分张量而不是所有张量,例如: fromsafetensorsimportsafe_opentensors={}withsafe_open("model.safetensors",framework="pt",device=0)asf:tensor_slice=f.get_slice("embedding")vocab_size,hidden_dim=tensor_slice.get_shape()tensor=tensor_slic...
在这个示例中,我们首先导入了必要的库,然后使用safe_open函数打开safetensors文件,并遍历文件中的所有键值对来构建一个状态字典。最后,我们将这个状态字典应用到已有的PyTorch模型实例上。 方法二:使用支持safetensors格式的第三方库 除了Hugging Face提供的API外,一些第三方库也可能支持safetensors格式。你可以查找这些...
System Info Hi, I'm having an issue with one of my safetensors files, eventually, it seems safe_open() would fail if metadata contains an integer value. In the attached zip file, there're two .safetensors files, the only difference is in...
System Info Currently when using safe_open as a context manager, mypy will complain that "safe_open" has no attribute "__enter__" and "safe_open" has no attribute "__exit__" Information The official example scripts My own modified script...
本文介绍了一种将Hugging Face上bin格式的大模型文件,在线转换为safetensors文件格式,然后下载到本地的方法。 技术背景 本文主要介绍在Hugging Face上把bin格式的模型文件转为safetensors格式的模型文件,并下载到本地的方法。 bin转safetensors 首先安装safetensors: ...

(if * loading suddenly stops working on a prelinked library, this is * a good one to check) * - write a trivial app that calls sleep() then dlopen(), attach * to it with "strace -p <pid>" while it sleeps, and watch for * attempts to open nonexistent dependent shared libs * *...
with safe_open("model.safetensors", framework="pt", device=0) as f: for k in f.keys(): tensors[k] = f.get_tensor(k) 这样得到的结果基本上就可以当pytorch的state_dict用了。 跨框架用法 .safetensors支持五种框架,包括pytorch、TensorFlow、flax(jax)、paddle(paddlepaddle)、numpy。对每个框架...
