一、yaml包的介绍
yaml是一种文件格式,跟json一样通常被用作配置文件,但远比 JSON 格式方便!使用json作为配置文件的朋友会发现,在json中写注释要通过增加键值对的形式来,但是yaml格式就非常的友好!
建议使用yaml来写配置文件,如下为yaml格式的示例:
二、使用报错及安装成功
我训练模型的时候,出现了错误,如下所示:
Traceback (most recent call last):File "train.py", line 24, in <module>import yamlModuleNotFoundError: No module named 'yaml'
ModuleNotFoundError: No module named 'yaml'
说明我们的环境中缺乏yaml包,尝试安装:
pip install yaml
但是报错:
Looking in indexes: http://mirrors.aliyun.com/pypi/simpleERROR: Could not find a version that satisfies the requirement yaml (from versions: none)ERROR: No matching distribution found for yaml
其实正确的命令行内容应该是如下所示:
pip install pyyaml
这样就成功了!如下所示:
