如何检查安装了哪个版本的 Keras？

小开

最佳答案

Python library authors put the version number in <module>.__version__. You can print it by running this on the command line:

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

If it's Windows terminal, enclose snippet with double-quotes like below

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

You can write:

python
import keras
keras.__version__

For terminal, run: (Change with python3 for version of Python3)

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

Or if you want to check inside code, include:

import keras
print(keras.__version__)
