Describe the problem

For text classification, after I uploaded the text documents and defined the labels per the instruction, I clicked the annotate data tab, but it only showed an empty page, any clues what went wrong?

Thank you for reporting the issue.

I confirmed doccano on Windows 10 & Python 3.6.4 it works fine (version is
a little different but it may not affect phenomenon).

If you don't have any data, you can confirm your label like following.

1. Do you use master branch?
2. Can you confirm your data at Dataset page on your project?
3. Can you confirm your label at Labels page on your project?
4. Can you provide samples of your uploaded data?

Thank you for your reply!

• Yes, I use the 'master' branch
• Below are the screenshots of the Dataset and Labels page:

• And here is the text file I used
  Test.txt

Thank you for your environment information!

I can setup the project by your data.

You use doccano at offline environment? doccano uses internet connection to load Javascript / CSS files.

[xuanlv2]

Thank you for your reply!
I do not use it at offline environment, the internet connection is always on.
Could it be the browser's problem?
I tried to play with the live demo, but it also gave me the similar empty page.

[icoxfog417]

Can you use Google Chrome? We mainly use Chrome for developing the doccano.

[xuanlv2]

I am actually using Google Chrome.
When I refresh the annotation page, the contents blinks for like a second, and then disappear.

[icoxfog417]

Oh, it's odd situation. Could you show us the Chrome console message (like #49)? JavaScript error would be logged there.

[xuanlv2]

That's the error message when I was trying to check the demo:

I have the same problem as you

After you create a project, upload data, create labels, you can just click 'Annotate data' button to the annotation page.
The error you meet is because you click the 'Try Demo' button in the homepage (click doccano icon in the top left corner), and this is only for demonstration. If you are on the homepage, you should click the 'Project' button in the top right corner. You can find the project you created and click the project name to start annotation.

Thank you for your reply, this is the annotation page I have:

@xuanlv2 @huojianzhatian
I got the same problem. Here is a quick fix by replacing

<script src="https://unpkg.com/marked@0.3.6"></script>
<script src="https://unpkg.com/lodash@4.16.0"></script>

in the file app\server\templates\annotation\annotation_base.html

with the following paths:

<script src="https://cdnjs.cloudflare.com/ajax/libs/marked/0.5.2/marked.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.js"></script>

After that, the annotation works well for me.

I made a pull request to fix this bug. Please let me know if you have further issues.

[BrambleXu]

Hi @Xinyi2016, thanks to your update. Did you know why this bug occur? It is really weird that we can not reimplement this bug.

[huojianzhatian]

@Xinyi2016 Thanks a lot, the annotation works well for me then.

[huojianzhatian]

@BrambleXu Thanks!

[Xinyi2016]

@BrambleXu Seems that those two links are broken, but you have loaded them successfully before. Have you tried reimplementing it in a new environment, like a New Incognito Window of Chrome?

[BrambleXu]

@Xinyi2016 Yes. I tired incognito window and it worked fine.

[icoxfog417]

I can get status 200 from https://unpkg.com/marked@0.3.6 by curl script. So browser cache seems to be not cause. But it will be good to describe until *.js file.

@Xinyi2016 , @xuanlv2 , @huojianzhatian , would you confirm below fix is effective to load annotation page, please?

Before

<script src="https://unpkg.com/marked@0.3.6"></script>
<script src="https://unpkg.com/lodash@4.16.0"></script>

After

<script src="https://unpkg.com/marked@0.3.6/lib/marked.js"></script>
<script src="https://unpkg.com/lodash@4.16.0/lodash.js"></script>

[xuanlv2]

@Xinyi2016 thank you sooo much!
It works for me now!

Why don't just use local copies of this js scripts and not rely on external provider?

I'm having the same problem. I'm using linux 18.04. The demo works fine, but after logging in I cannot annotate text. The right click or selecting text doesn't work. What should I do?
