Question

我正在使用Anaconda。当我执行conda list时，它表明当前已安装scikit-learn 0.19.1。我想升级到0.19.2，所以我正在做

conda config --append channels conda-forge
conda install scikit-learn=0.19.2

但是随后出现以下错误：

PackagesNotFoundError: The following packages are not available from current cha
nnels:

  - scikit-learn=0.19.2

Current channels:

  - https://repo.anaconda.com/pkgs/main/win-64

如何安装scikit-learn 0.19.2？

Answer 1

scikit-learn==0.19.2您缺少第二个=符号，因此找不到包

$ pip install scikit-learn=0.19.1
Invalid requirement: 'scikit-learn=0.19.1'
= is not a valid operator. Did you mean == ?

Anaconda无法更新scikit-learn
