在导入guesslang软件包时，我发现关于ContextualVersionConflict软件包的html5lib错误。
ContextualVersionConflict: (html5lib 1.0.1 (/Users/user_name/.pyenv/versions/anaconda3-5.1.0/lib/python3.6/site-packages), Requirement.parse('html5lib==0.9999999'), {'tensorboard'})
我重新安装了html5lib版本的1.0.1，并再次安装了版本0.9999999（七个9s），但是两次尝试的结果是相同的。
这是我运行的代码。
from guesslang import Guess
code_snippet = "import numpy as np"
print(Guess().language_name(code_snippet))
整个错误消息。
