python - 无法安装 Keras

Question

我一直无法在 Anaconda 环境中安装 Keras……

~$ pip install keras
pip install keras
Collecting keras
Collecting pyyaml (from keras)
  Using cached PyYAML-3.12.tar.gz
    Complete output from command python setup.py egg_info:
    running egg_info
    creating pip-egg-info/PyYAML.egg-info
    writing top-level names to pip-egg-info/PyYAML.egg-info/top_level.txt

    writing pip-egg-info/PyYAML.egg-info/PKG-INFO
    writing manifest file 'pip-egg-info/PyYAML.egg-info/SOURCES.txt'

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-b74rx7yf/pyyaml/

我已经尝试了一些常见的嫌疑人:

pip install --upgrade pip
pip install --upgrade setuptools

而且我也尝试了大部分的解决方案here , 但仍然没有运气。

顺便说一句，当不在 conda 环境中时，我可以很好地安装 Keras。

如有任何帮助，我们将不胜感激。

谢谢大家的支持!

无论出于何种原因，我的 conda env 即使在运行后仍卡在 setuptools-27 上

pip install --upgrade setuptools

然而，运行

pip install --upgrade setuptools --ignore-installed

将我的环境升级到 setuptools-28.8.0，现在没有 Keras 问题
