I wrote a simple program to add two float32 tensors in ggml using CUDA, and that works fine. But when I changed the two tensor types toGGML_TYPE_F16and tried to add them, I got a GGML assertion error: ggml-cuda\binbcast.cu:297: GGML_ASSERT(src1->type == GGML_TYPE_F32) fa...
(1)r=S(q−Z) (看不懂的可以再参考一下我之前的文章) 这里面 r 是实数域中的数值 (一般是 float),q 则是量化后的整型数值 (常用的是 int8)。 EltwiseAdd 就是对两个 tensor 的数值逐个相加。假设两个 tensor 中的数值分别是 r1、r2,相加得到的和用 r3 表示,那全精度下的 EltwiseAdd 可以表示为...
除了需要对输出按照[Math Processing Error]放缩外,其中一个输入也需要按照[Math Processing Error]进行放缩,这一步就是论文中提到的 rescale。 这一部分的代码我就不准备在 pytorch 中实现了,毕竟这个模块的量化最主要的就是统计输入跟输出的 minmax,因此训练代码几乎没什么内容,主要的工作都是在推理引擎实现的。因此...
PyTorch is a Python package that provides two high-level features: Tensor computation (like NumPy) with strong GPU acceleration Deep neural networks built on a tape-based autograd system You can reuse your favorite Python packages such as NumPy, SciPy, and Cython to extend PyTorch when needed. ...
记录最近使用pytorch出现的一个大坑,花了3天的时间调试 代码来自于 detectron2,在修改dd3d和monodetr代码的时候,将backbone改为detectron2中提供的FPN(Backbone)类时,出现了无法进行Dataparallel的情况,错误提示: RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cu...
NNCF provides the use of implemented optimization methods in two different ways: by means of supported training samples or through integration into the custom training code. Using NNCF within your training code Let us describe the steps required to modify an existing PyTorch training pipeline to inte...
这段代码首先将进程 0 和 1 组成进程组,然后将各自进程中 tensor(1) 相加。由于我们需要组中所有张量的总和,因此我们将 dist.reduce_op.SUM 用作化简运算符。一般来说,任何可交换的数学运算都可以用作运算符。PyTorch 开箱即用,带有 4 个这样的运算符,它们...

And you could see each one of these Blackwell dies, two of them connected together, you see that? It is the largest die, the the largest chip the world makes, and then we connect two of them together with a 10 te...
The reason why I didn't land that was because in legacy_load, constructor would be called before storages of indices/values are set. So the tensor would not actually be validated. Technically, torch.sparse.{Foo}Tensor should not even be called by our rebuild process since afaict this was ...
