mobileNet-SSD-keras的error解決

soup = BeautifulSoup(f, 'xml')

NameError: name 'BeautifulSoup' is not defined

打開檔案，發現需要導入

from bs4 import BeautifulSoup
           

這是解析資料集需要的。然後

pip install bs4

但是出現新的錯誤：

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

再安裝lxml

pip install lxml

現在可以運作了。
