我通过软件中心安装了 BALLView，虽然程序启动正常，但无法正确为模型着色。查看已设置的不同化学元素的调色板，我已检查并重新检查以确保颜色为 CPK 颜色，但无论我做什么，每当我选择按元素为模型着色时，整个元素都会变成白色。例如，请参见下面的屏幕截图。我还注意到，我不断在其界面中收到 python 终端错误，指出未安装 pywidgets。这是该错误（顺便说一句，您也可以在下面的屏幕截图中看到它）：
ERROR: Version of imported sip module is not compatible with the version BALL was built against.
If BALL was compiled using SIP version x.y.z then it can be used with any SIP version x.y.z' where z' >= z.
Got (from <module 'sip' from '/usr/lib/python2.7/dist-packages/sip.i386-linux-gnu.so'>) 4.16.6; Expected 4.15.5
No Python support available! (See PyWidget)
