Open Data Cube 说明

本文记录 2023年Open Data Cube 安装过程及说明

datacube 1.8.17.dev2+g0cfe300d.d20231027

1 Install the Open Data Cube Software ODC 核心安装

ODC8.16 以后的版本要求python 3.10 建议直接安装Ubuntu 22，它自带的版本是Pyhon 3.10.12

1.1 mamba 安装

按照上面的安装步骤，需要使用mamba安装ODC所需的核心环境。使用mamba需要安装Miniforge。 github上的安装命令如下：

curl -L -O "https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname -m).sh"
bash Miniforge3-$(uname)-$(uname -m).sh

或者

wget "https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname -m).sh"
bash Miniforge3-$(uname)-$(uname -m).sh

中国的网络访问github会有间歇性断流，可以直接在GITHUB上下载，再运行bash命令安装安装完的配置工作最好在虚拟环境下完成

2 S2 indexing

按照github上的内容Indexing Sentinel-2 Cloud-Optimised GeoTIFFs进行操作即可。

3 其他常用应用

3.1 Python

显示所有已存在的虚拟环境列

conda info --envs

列出所有安装在该虚拟环境中的包名和版本号

conda list -n <env_name>

列出所有已存在的虚拟环境列表，并附带其路径信息

conda env list

3.2 PostgresQL

直接在官方网站找安装说明，比什么都靠谱。

sudo sh -c 'echo "deb https://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get -y install postgresql

3.3 pgadmin4

直接在官方网站找安装说明，比什么都靠谱。
此外，pgadmin4 分为web端和desktop端，可以安装两个，也可以只安装一个。

#
# Setup the repository
#

# Install the public key for the repository (if not done previously):
curl -fsS https://www.pgadmin.org/static/packages_pgadmin_org.pub | sudo gpg --dearmor -o /usr/share/keyrings/packages-pgadmin-org.gpg

# Create the repository configuration file:
sudo sh -c 'echo "deb [signed-by=/usr/share/keyrings/packages-pgadmin-org.gpg] https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list && apt update'

#
# Install pgAdmin
#

# Install for both desktop and web modes:
sudo apt install pgadmin4

# Install for desktop mode only:
sudo apt install pgadmin4-desktop

# Install for web mode only: 
sudo apt install pgadmin4-web 

# Configure the webserver, if you installed pgadmin4-web:
sudo /usr/pgadmin4/bin/setup-web.sh

3.4 Jupyter notebook

直接在官方网站找安装说明,比什么都靠谱。

pip install notebook

4 可能出现的错误

ERROR: Could not build wheels for aiohttp, which is required to install pyproject.toml-based

造成这一原因的问题是虚拟环境中安装了Python 3.12 AOIHTTP 包不兼容，可以将Python降低到3.10，也可以在3.12环境中安装 Basically, Python 3.12 is not supported yet in regular releases. For Python 3.12 install the beta 3.9.0b0.

pip install aiohttp==3.9.0b0

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. datacube 1.8.17.dev2+g0cfe300d.d20231027 requires jsonschema<4.18, but you have jsonschema 4.19.1 which is incompatible. Attempting uninstall: jsonschema Found existing installation: jsonschema 4.17.3 Uninstalling jsonschema-4.17.3: Successfully uninstalled jsonschema-4.17.3 ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. jupyter-events 0.8.0 requires jsonschema[format-nongpl]>=4.18.0, but you have jsonschema 4.17.3 which is incompatible. jupyterlab-server 2.25.0 requires jsonschema>=4.18.0, but you have jsonschema 4.17.3 which is incompatible.

上述问题是jupyter notebook 中使用的 jsonschema 和 Open datacube中使用的jsonschema版本不一致造成的，解决方案是降低jupyter notebook的版本，安装6.4.8（Jupyter 7 以上的jsonschema版本高）

pip uninstall notebook
pip install notebook==6.4.8

TypeError: warn() missing 1 required keyword-only argument: 'stacklevel' ModuleNotFoundError: No module named ‘jupyter_server.contents

安装完成后，无法启动，出现上述错误，是由于traitlets版本造成的。需要卸载并制定对应的版本

pip uninstall traitlets
pip install traitlets==5.9.0

ModuleNotFoundError: No module named 'yaml'

包名不是yaml 是pyyaml
