google-colaboratory - XLNetTokenizer 需要 SentencePiece 库，但在您的环境中未找到

Question

我正在尝试在 Google Collaboratory 上实现 XLNET。但我得到以下问题。

ImportError: 
XLNetTokenizer requires the SentencePiece library but it was not found in your environment. Checkout the instructions on the
installation page of its repo: https://github.com/google/sentencepiece#installation and follow the ones
that match your environment.

我也尝试了以下步骤：

!pip install -U transformers
!pip install sentencepiece

from transformers import XLNetTokenizer
tokenizer = XLNetTokenizer.from_pretrained('xlnet-base-cased-spiece.model')

提前谢谢你的帮助。
