我无法使用最新版本的 Anaconda 来导入 pylab (Linux 64 位)。其他包似乎工作正常。 (注意:我没有 su-đu-t 访问权限)

如果我尝试

> conda install sip

我得到:

我也遇到错误:

Có ý tưởng gì không?

刚遇到这个问题，它与 matplotlib 尝试使用的 qt 后端有关，尝试:

import PyQt4

如果你没有 PyQt4，你可能有 PySide

import PySide

如果是这种情况，您需要设置 matplotlib.rcParams['backend.qt4'] == 'PySide' thay vì 'PyQt4'。您也可以在 matplotlibrc 文件中执行此操作 (~/.matplotlib/matplotlibrc)

# find and change line:
backend.qt4 : PySide

注意:如果您没有 matplotlibrc 文件，您可以从 matplotlib 源目录中复制它

nhập khẩu chúng
import matplotlib
mpl_dir = os.path.dirname(matplotlib.__file__)
os.system("cp {}/mpl-data/matplotlibrc ~/.matplotlib/".format(mpl_dir))
