tf- colab中的语句导入错误(导入路径很奇怪)

Question

我在colab输入tf-句子时出错了。

我使用的是tensorflow 2.0版本，并安装了tf-句子。

!pip install --upgrade pip
!pip install tensorflow==2.0.0-rc1
!pip3 install --quiet tensorflow-hub
!pip3 install --quiet seaborn
!pip3 install sentencepiece
!pip3 install tf_sentencepiece

但是，当我试图导入tf-句子时，会发生以下错误

/usr/local/lib/python3.6/dist-packages/tf_sentencepiece/sentencepiece_processor_ops.py:43: UserWarning: No so file is found for [2.0.0-rc1] from [3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.1.11.0, 3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.2.0.0-beta1, 3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.1.7.0, 3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.1.14.0, 3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.1.9.0, 3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.1.8.0, 3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.1.10.0, 3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.1.13.1]

因此，手动进入目录，检查哨兵表_processor_ops.so.2.0.0-beta是否存在。奇怪的是，它在文件夹中，但在不同的不同路径。colab尝试从/usr/local/lib/python3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.2.0.0-beta1导入文件(路径很奇怪，应该注意到.)但是该文件实际上存在于/usr/local/lib/python3.6/dist-packages/tf_sentencepiece/_sentencepiece_processor_ops.so.2.0.0-beta1中。

为什么colab里奇怪地设置了这条路？我该如何解决这个问题？

Answer 1

用tensorflow_text安装!pip3 install tensorflow_text>=2.0.0rc0解决了这个问题--这个包包含SentencepieceOps。还是不知道为什么这条路会很奇怪，尽管.
