mobileNet-SSD-keras的error解决

soup = BeautifulSoup(f, 'xml')

NameError: name 'BeautifulSoup' is not defined

打开文件，发现需要导入

from bs4 import BeautifulSoup
           

这是解析数据集需要的。然后

pip install bs4

但是出现新的错误：

bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: xml. Do you need to install a parser library?
           

再安装lxml

pip install lxml

现在可以运行了。
