你好， 按照步骤配置好虚拟环境后， 执行如下： haiyun@dell-Precision-Tower-5810:~$ source ~/deep_ocr_env/bin/activate && cd ~/deep_ocr && ./bin/deep_ocr_reco data/holiday_notification.jpg -v -d ! image to reco: data/holiday_notification.jpg Traceback (most recent call last): File "./bin/deep_ocr_reco", line 137, in show_img(raw, title="raw image") File "./bin/deep_ocr_reco", line 27, in show_img plt.gray() File "/home/haiyun/deep_ocr_env/lib/python2.7/site-packages/matplotlib/pyplot.py", line 3932, in gray set_cmap("gray") File "/home/haiyun/deep_ocr_env/lib/python2.7/site-packages/matplotlib/pyplot.py", line 2372, in set_cmap im = gci() File "/home/haiyun/deep_ocr_env/lib/python2.7/site-packages/matplotlib/pyplot.py", line 335, in gci return gcf()._gci() File "/home/haiyun/deep_ocr_env/lib/python2.7/site-packages/matplotlib/pyplot.py", line 601, in gcf return figure() File "/home/haiyun/deep_ocr_env/lib/python2.7/site-packages/matplotlib/pyplot.py", line 548, in figure **kwargs) File "/home/haiyun/deep_ocr_env/lib/python2.7/site-packages/matplotlib/backend_bases.py", line 161, in new_figure_manager return cls.new_figure_manager_given_figure(num, fig) File "/home/haiyun/deep_ocr_env/lib/python2.7/site-packages/matplotlib/backends/_backend_tk.py", line 1044, in new_figure_manager_given_figure window = Tk.Tk(className="matplotlib") File "/home/haiyun/install/python-2.7.11/lib/python2.7/lib-tk/Tkinter.py", line 1814, in init self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: couldn't connect to display ":0" 在网上搜索“_tkinter.TclError: couldn't connect to display ":0"” 尝试去解决没有成功， 烦请指点! 多谢！
