【深度学习环境-3】Ubuntu 18.04安装配置ZED2环境

Install the ZED Python API | Stereolabs

ZED SDK 3.2 - Download | Stereolabs

1、下载对应的ZED SDK 

 2、ZED SDK安装

chmod +x ZED_SDK_Ubuntu18_cuda11.0_v3.2.2.run
./ZED_SDK_Ubuntu18_cuda11.0_v3.2.2.run

3、测试

cd /usr/local/zed/tools
./ZED_Depth_Viewer

踩坑记录：

1、先安装了ZED SDK 3.5.6，import pyzed成功，但import pyzed.sl失败，显示illegal instructions，故打算卸载ZED SDK 3.5.6，重新安装3.2.2。

若安装过不同版本的ZED SDK，则可能会导致模块导入失败，需要全部卸载。

#/usr/local/zed 这个目录全部删掉
sudo rm -rf zed
pip3 uninstall pyzed
pip uninstall pyzed

可以通过sudo find -name zed（zed sdk pyzed）等关键词查询把以前安装过的全部删除干净

2、ZED python API安装失败

在安装ZED SDK的过程中，可能因为网络问题，ZED python API安装失败，可采用以下方式：

dell@dell-Precision-3640-Tower:/usr/local/zed$ python3 get_python_api.py 
CUDA 11.0
Platform ubuntu18
ZED 3.2
Python 3.6
Downloading python package from https://download.stereolabs.com/zedsdk/3.2/ubuntu18/cu110/py36 ...

3、有时在安装过程中出现依赖包安装失败的问题，建议更换源。

# 备份源文件
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
# 增加以下源文件
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
# 更新源
sudo apt-get update

 # 慎用！慎用！慎用！

# 升级软件，有的博文推荐使用此命令，但此命令慎用，会导致内核升级，无法开机，

sudo apt-get upgrade
