在Pyarm中安装Keras导致故障

Question

我试图使用Keras进行时间序列预测，但在安装Keras库时遇到了一个错误。 以下是我收到的一条错误消息：

DEPRECATION: The -b/--build/--build-dir/--build-directory option is deprecated and has no effect anymore. pip 21.1 will remove support for this functionality. A possible replacement is use the TMPDIR/TEMP/TMP environment variable, possibly combined with --no-clean. You can find discussion regarding this at https://github.com/pypa/pip/issues/8333.

我已经尝试过不同的解决方案，比如将Python解释器从3.9降级到3.7，将pip更新到一个新版本，但到目前为止没有任何效果。现在我完全累坏了

Answer 1

确保已安装64位python

此错误可能是由于旧的pip版本造成的。升级pip：

pip3 install upgrade pip

然后尝试直接安装h5py：

pip install h5py

并重新安装Keras：

pip install keras
