LocalTileLayer does not appear on map

[agirnow]

Hello !

First of all thanks for the work, this library sounds amazing and I can't wait to try it.

However, I still have difficulties to run the introduction notebooks from my machine (Ubuntu 22). When lauching introduction.ipynb as a jupyter notebook, I have this JavaScript error at block 7 when layer is added on the map :

Failed to create view for 'UrlView' from module 'ipyurl' with model 'UrlModel' from module 'ipyurl'
ReferenceError: process is not defined

    at http://localhost:8888/nbextensions/jupyter-js-widgets/extension.js?v=20230426160827:2:747630 

My environment was created from scratch using /binder/environment.yml with python 3.10, notably my ipyurl version is 0.1.2 and my xarray-leaflet version is 0.1.16

Here are my jupyter versions :

• IPython : 8.12.0
• ipykernel : 6.22.0
• ipywidgets : 8.0.6
• jupyter_client : 8.2.0
• jupyter_core : 5.3.0
• jupyter_server : 1.24.0
• jupyterlab : 3.6.3
• nbclient : 0.7.3
• nbconvert : 7.3.1
• nbformat : 5.8.0
• notebook : 6.5.4
• qtconsole : not installed
• traitlets : 5.9.0

Many thanks for any help !

Hi @agirnow, thanks for the kind works! What version of ipyurl do you have? Try installing v0.1.3, which requires ipywidgets>=7,<8.

[agirnow]

Thanks for your reply !

I have updated ipywidgets to 7.6.0 and ipyurl to 0.1.3, and it removed the JavaScript error I had before. However, I still do not have anything that displays on the map, executing block 7 just relocates the map to the zone of interest without displaying anything...

Do you have any idea about what can cause this ?

Many thanks, Alexandre

[agirnow]

Any idea @davidbrochart ?

[davidbrochart]

Any error reported in the browser console?

[agirnow]

Yes, here they are

[davidbrochart]

Could you provide the output of pip list, or the equivalent if it's a conda environment?

[agirnow]

env.txt Here you will find the complete list of my conda environment.

[davidbrochart]

I think your environment is not clean, I see:

jupyter-server=1.24.0=pypi_0
jupyter_server=2.5.0=pyhd8ed1ab_0

Could you try again with a fresh env?

[agirnow]

Thanks, it seems that I am making progress !

Now I have a colorbar that displays but no data and map, and a collection of errors like this :

[E 16:07:11.517 NotebookApp] Error unpacking user from cookie: Expecting value: line 1 column 1 (char 0)
[W 16:07:11.517 NotebookApp] Clearing invalid/expired login cookie username-localhost-8888

[davidbrochart]

Can you provide your environment details again?

[agirnow]

Sure ! env2.txt

[davidbrochart]

With your environment, it works fine on my side, using JupyterLab. It looks like you have authentication issues with Notebook?

@davidbrochart the weekend brought advice, i no longer have issues with the introduction notebooks, everything is working fine ! Many thanks for your help :)
