使用 CMake 在 Google colab 上构建 dlib

Question

我正在尝试在 Google colaboratory (Ubuntu 18.04 (Bionic Beaver)) 上安装 dlib，但出现错误。

CMake 错误：

The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_cublas_LIBRARY (ADVANCED)
linked by target "dlib" in directory /content/dlib/dlib
CUDA_curand_LIBRARY (ADVANCED)
linked by target "dlib" in directory /content/dlib/dlib
cusolver (ADVANCED)
linked by target "dlib" in directory /content/dlib/dlib

-- Configuring incomplete, errors occurred!

Google colab 已经在 /usr/local/cuda-9.2/targets/x86_64-linux/lib.

中拥有这些库

如何 link CMake 的路径，以便它可以找到这些库？

这是重现错误的 Google 协作 link。请注意，您需要从 developer.nvidia.com 下载 cudnn 文件。您需要登录，但可以免费下载该文件。 https://colab.research.google.com/drive/1IiOLDP20QT3JFx5pigCibDadq9orNErk

Answer 1

dlib 现已预装在 colab 上，因此您可以通过以下方式轻松解锁：

import dlib
help(dlib)

Answer 2

在 GCP Ubuntu20.04 上安装机器类型 n2d-standard-8（8 个 vCPU，32 GB 内存）

git clone https://github.com/Universe-ML21/script_install_dlib.git
sudo chmod +x script_install_dlib/auto_dlib.sh
bash script_install_dlib/auto_dlib.sh
