python - 带有深思熟虑的冠层的 scipy

Question

我正在评估 Enthought 包。我在Ubuntu中安装了32位canopy(从https://www.enthought.com/downloads/下载)。

$ sudo bash canopy-1.0.1-rh5-32.sh

经测试，我在 /usr/local/Canopy/appdata/canopy-1.0.0.1160.rh5-x86/lib/python2.7/site-packages 中没有看到 scipy:

$ /usr/local/Canopy/appdata/canopy-1.0.0.1160.rh5-x86/bin/python

    raise ImportError(missingwxversion)


ImportError: Matplotlib backend_wx and backend_wxagg require wxversion, which was not found.

请帮我:如何安装Python Canopy(包括scipy、matplotlib等)？我必须手动安装它们吗？我以为安装程序 shell 脚本会自动安装所有这些。我错过了什么吗？

Scipy 安装到不同的 virtual environment 中(~/Enthought/Canopy_64bit/System/)。一般来说，您应该运行 ~/Enthought/Canopy_64bit/User/bin/python 中提供的 Python，如 here 中所述。 。另请参阅this article有关如何将 Canopy 设置为默认 Python 的信息
