自定义图标未在图中显示为代码
我正在尝试在此Python图中使用自定义节点类型作为代码库（网站/文档]＆amp;以下是我的代码（一个最小的可重现示例段））：
from diagrams import Diagram
from diagrams import Edge
from diagrams.custom import Custom
from diagrams.gcp.devtools import ContainerRegistry
from diagrams.gcp.ml import AIPlatform
with Diagram(name="my_diagram",
filename="diagrams/my_diagram_rec",
show=True,
):
# nodes
vertexai = AIPlatform("Vertex AI")
gcr = ContainerRegistry("Container Registry")
gitlab_repo = Custom("Git Repo", "./diagrams/resources/gitlablogo.png")
# diagram structure includind Edge attributes
gitlab_repo >> Edge(label="Code \nConfig.yml \nEnvironment.yml") >> gcr
gcr >> Edge(label="Docker Image") >> vertexai
vertexai >> Edge(label="launches \nspecified \nmachine-size")
并确认gitlablogo.png在位置上存在文件，我将其引用：
~/my-repo issue49-diagrams $ ls diagrams/resources ok py 17:24:23
gitlablogo.png
但是当我运行python图表/so_q_diagram.py.py.py.py时，弹出的图像不会显示我的自定义图标（gitlab徽标）：
I'm trying to use a Custom Node Type in this python diagrams as code library (website/docs] & pypi link). Below is (a minimal reproduceable example snippet of) my code:
from diagrams import Diagram
from diagrams import Edge
from diagrams.custom import Custom
from diagrams.gcp.devtools import ContainerRegistry
from diagrams.gcp.ml import AIPlatform
with Diagram(name="my_diagram",
filename="diagrams/my_diagram_rec",
show=True,
):
# nodes
vertexai = AIPlatform("Vertex AI")
gcr = ContainerRegistry("Container Registry")
gitlab_repo = Custom("Git Repo", "./diagrams/resources/gitlablogo.png")
# diagram structure includind Edge attributes
gitlab_repo >> Edge(label="Code \nConfig.yml \nEnvironment.yml") >> gcr
gcr >> Edge(label="Docker Image") >> vertexai
vertexai >> Edge(label="launches \nspecified \nmachine-size")
And confirmation that the gitlablogo.png file exists at the location I reference it at:
~/my-repo issue49-diagrams $ ls diagrams/resources ok py 17:24:23
gitlablogo.png
But when I run python diagrams/so_q_diagram.py, the image that pops up doesn't show my custom icon (the gitlab logo):

好的，这很烦人，感觉就像一个错误，但显然包括
fileName带有图（... 语句导致自定义图标消失。gitlablogo.png的位置，在上面运行一个单个更改的确切代码 - 征服fileName =“ difagrams/my_diagram_rec_rec”，- 现在使图映像渲染图像正如预期的：ok this was annoying and feels like a bug but apparently including a
filenameparam in thewith Diagram(...statement causes the custom icon to disappear. Because, without changing the location ofgitlablogo.png, running the exact code above with one single change --commenting outfilename="diagrams/my_diagram_rec",-- now causes the diagram image to render as expected:以前的答案对我不起作用。我发现您必须下载图标PNG，而不仅仅是图片以使自定义功能起作用。您可以在您的情况下使用诸如“ gitlab徽标图标”之类的内容，并且您应该能够找到没有任何背景的徽标图标（看起来像网格或马赛克）。然后使用您现在拥有的相同代码，并且应该使用。希望这有帮助。

我的结果也附有：

The previous answer doesn't work for me. I found that you have to download the icon png instead of just a picture to make the Custom function work. You can google something like "GitLab logo icon" for your situation, and you should be able to find a logo icon without any background (look like grids or mosaic). Then use the same codes you have now and it should work. Hopefully, this is helpful.

如果有人仍在挣扎，我建议您提及您图标资源的完整途径。 我
放置：project/resources/icon.png
经过大量探索，我最终在文件系统中提供了Icon.png文件的完整路径：/home/＆lt; sub-directories＆gt;/project/resources/resources/icon。 PNG
对我有用，这应该在文档中存在！
If anyone is still struggling, I would suggest to mention the full path to your icon resource. In my case I had a nested folder structure something like:
placed: project/resources/icon.png
After much exploration, I ended up providing the full path of the icon.png file in my file system: /home/<sub-directories>/project/resources/icon.png
And it worked for me,this should have been there in the documentation!
我也遇到了同样的问题，从我得到的问题中，这来自我正在使用的
fileName参数（）。就我而言，要解决问题并使图标PNG正确渲染，我使用了从**
fileName =**的相对路径，位置并指向图标png存储的位置。I had the same issue and, from what I get, this is coming from the use of the
filenameparameter in theDiagram()that I was using.In my case, to solve the issue and get the icon PNG to render properly, I used a relative path starting from the**
filename=**location and pointing to where the icon PNG is stored.
