SciKit-Learn 的分解模块中未安装 LatentDirichletAllocation

问题描述

我在 SciKit-Learn 包中遇到了一些奇怪的问题.SciKit-Learn 包中有一个分解"模块，它应该包含 LatentDirichletAllocation([…]) 函数.请参阅此处的文档:"https://scikit-learn.org/stable/modules/classes.html#module-sklearn.decomposition"

I got some strange problem at SciKit-Learn package. There is "decomposition" module inside SciKit-Learn package, which should contain LatentDirichletAllocation([…]) function. See documentation here:"https://scikit-learn.org/stable/modules/classes.html#module-sklearn.decomposition"

当我尝试导入分解"模块时:from sklearn import as 分解它给出了错误:

When I tried to import "decomposition" module: from sklearn import as decompositionit gives error:

Traceback (most recent call last):
  File "tf_1_day_scikit_dnn.py", line 12, in <module>
    from sklearn import decomposition
  File "/home/developer1/.local/lib/python3.6/site-packages/sklearn/decomposition/__init__.py", line 19, in <module>
    from ._online_lda import LatentDirichletAllocation
ImportError: cannot import name 'LatentDirichletAllocation'

命令:ls -al ~/.local/lib/python3.6/site-packages/sklearn/decomposition 显示:

大部分函数都在这里，但没有LatentDirichletAllocation"函数的痕迹.但我确实在 _online_lda.py 文件中看到了 LatentDirichletAllocation 类.

Most of the functions are here but there are no traces of the "LatentDirichletAllocation" function. Yet I did see LatentDirichletAllocation class defined in the _online_lda.py file.

命令 python3 -c "import sklearn; sklearn.show_versions()" 打印所有需要的版本:

Command python3 -c "import sklearn; sklearn.show_versions()" prints all versions required:

System:
    python: 3.6.8 (default, Oct  7 2019, 12:59:55)  [GCC 8.3.0]
executable: /usr/bin/python3
   machine: Linux-4.15.0-65-generic-x86_64-with-Ubuntu-18.04-bionic

Python dependencies:
       pip: 9.0.1
setuptools: 42.0.2
   sklearn: 0.22
     numpy: 1.17.4
     scipy: 1.3.3
    Cython: None
    pandas: 0.25.3
matplotlib: 3.1.2
    joblib: 0.14.0

Built with OpenMP: True

所以我假设这里满足所有要求.(顺便说一句，SciKit-Learn 运行良好，直到我尝试导入分解"模块).

So I assume all requirements were met here. (BTW SciKit-Learn worked fine till I tried to import "decomposition" module).

我按照此处的描述安装了 SciKit-Learn 软件包:"https://scikit-learn.org/stable/install.html"使用命令 pip3 install -U scikit-learn我确实重新安装了几次，但得到了相同的结果.

I installed the SciKit-Learn package as it was described here: "https://scikit-learn.org/stable/install.html"using command pip3 install -U scikit-learnI did reinstall that several times but got same result.

我做错了什么?我是否需要将缺少的LatentDirichletAllocation"函数添加到分解"模块中?如果是这样 - 如何?我应该以不同的方式安装整个包吗?

What do I do wrong? Do I need to add missing "LatentDirichletAllocation" function into the "decomposition" module? If so - how? Should I install the whole package somehow different way?

谢谢.

推荐答案

我今天遇到了同样的问题.我回到scikit-learn 0.21之前的版本解决了:

I had the same problem today. I solved it by going back to the previous version 0.21 of scikit-learn:

pip3 install scikit-learn==0.21
