python - 导入错误 : No module named yaml in Keras (neural network)

Question

我已经成功安装了 Keras API 和 python 在 TensorFlow 上使用的其他要求，但是当我导入它时出现以下错误。

Traceback (most recent call last):

ImportError: No module named yaml

Answer 1

看起来你没有安装 yaml 模块，如果你使用带有 pip 的虚拟环境，请执行以下操作:

pip install yaml

如果您使用的是 anaconda，请执行以下操作:

conda install -c anaconda yaml
