问题描述
我必须使用顶层目录中的 -m 选项将bokeh脚本作为模块运行，因为它需要在同一目录下导入其他一些便携式模块
I have to run a bokeh script as a module using the -m option from the top directory, because it needs to import some other portable module under the same directory
python -m bokeh_module.bokeh_sub_module
目录树如下所示.通过运行以上命令，无论将png文件放在何处都不会显示图像，有没有办法解决此问题?谢谢您的帮助.
The directory tree is shown below. By running the above command, it doesn't show the image no matter where the png file is placed, is there a way to resolved the issue? Thank you for any help.
.
├── other_module
│ ├── __init__.py
│ └── other_sub_module.py
├── bokeh_module
│ ├── __init__.py
│ ├── image.png # not showing
│ └── bokeh_sub_module.py
└── image.png # not showing either
bokeh_sub_module.py
bokeh_sub_module.py
from other_module import other_sub_module
from bokeh.plotting import figure, show
# do something with other_sub_module
p = figure(match_aspect=True)
p.image_url( ['image.png'], 0, 0, 1, 1 ) # not showing
p.image_url( ['./bokeh_module/image.png'], 0, 0, 1, 1 ) # not showing either
show(p)
顺便说一句，如果我从 bokeh_module 目录运行 pytohn bokeh_sub_module.py ，则可以毫无问题地找到同一目录下的image.png.
By the way, if I run pytohn bokeh_sub_module.py from the bokeh_module directory, the image.png inside the same directory can be found with no problems.
推荐答案
image_url 需要URL，而您对 image_url 的调用均未使用URL.
image_url requires URLs, and neither of your calls to image_url use URLs.
尝试使用绝对URL，并在其前面添加 file://.
Try to use absolute URLs and add file:// in front of them.
