python 引用 from cuda import cudart Python 引用与对象关系,浅复制:仅复制对象的引用,而不开辟内存,即,改变复制后的对象时,其实是在改变原对象内存中的内容。b=a[:]深复制将开辟新的内存,把原对象内存中的内容复制到新的内存中来,如果改变复制后的对象,将改变原
发现python cuda 中 cudart.cudaMemcpy 的一个小问题, 当目标存储尺寸小于要复制数据的尺寸时, 竟然不报错, 不知何解.```pythonimport numpy as npfrom cuda import cuda, cudartx = np.random.randn(1, 3, 224, 224)size = x.itemsize * x.sizeerr, device_ptr = cudart.cudaMalloc(size // 2)ass...

既然是个cuda初始化就报错的问题,那Gemfield不妨先抛开PyTorch,在当前的Docker环境上直接写一个最简化的C程序来初始化CUDA设备,看看是否会出错。 代码: #include<stdio.h>#include<cuda_runtime.h>intmain(){intdevice=0;intgpuDeviceCount=0;structcudaDevicePropproperties;cudaError_tcudaResultCode=cudaGetDeviceCount...
将CUDA安装目录添加到%PATH%环境变量中: 如果cudart64_100.dll文件存在,但TensorFlow仍然报告找不到该文件,可能是因为该文件的目录没有被添加到系统的%PATH%环境变量中。你可以通过以下步骤将其添加到%PATH%: 右键点击“此电脑”或“计算机”,选择“属性”。 点击“高级系统设置”。 在“系统属性”窗口中,点击“...

That is all and the simplest way to do so. You can also make more wrappers to copy back your memory but this can also be done from the .c file because the cudaMemcpy’ are c compatible or how you call them… :P Note: you need to include the cuda.h or cudart.h in you .c fil...
