这需要单独下载:

# Download/Extract openfst, boost
download_extract('https://sites.google.com/site/openfst/home/openfst-down/openfst-1.6.7.tar.gz',
                  'third_party/openfst-1.6.7.tar.gz')
download_extract('https://dl.bintray.com/boostorg/release/1.67.0/source/boost_1_67_0.tar.gz',
                  'third_party/boost_1_67_0.tar.gz')

需要自行下载这两个文件,并把它们解压到third_party目录下,然后注释掉这两行。安装的时候你可能会遇见下面的问题:
