python - 如何在 conda 环境中安装 keras 2.0.5 版本

Question

我在 Windows 7 64 位上使用 anaconda。
这就是我所做的:

conda update conda
conda create --name my_env python=3.5
conda activate my_env
conda install -c conda-forge tensorflow=1.8

当我尝试安装 keras 2.0.5 时:

conda install keras=2.0.5

我收到这条消息:

Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible so lve. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible so lve.

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

• keras=2.0.5

Current channels:

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

To search for alternate channels that may provide the conda package you're looking for, navigate to

https://anaconda.org

and use the search bar at the top of the page.

我也试过:

conda install -c conda-forge keras=2.0.5

与上述消息相同。
我已经检查过是否已经安装了 keras:

python -c "import keras; print(keras.__version__)"

随着消息:

ImportError: No module named 'keras'

我搜索 keras 包:

conda search keras

随着输出:

如何安装 keras 2.0.5 版。在我的环境中？

Answer 1

您可以考虑使用 pip 安装并在 Conda 环境中支持。
使用命令:

pip install Keras==2.0.5

这不会抛出任何错误。
