Questions or issues that you may encounter when working with ArcGIS Notebook Server are listed, and solutions are suggested. If you don't find the problem you're looking for, you can also search for articles on the Esri Support center website.
Installation
Access to notebooks
- When I try to open a notebook, I get this error: Connection failed. A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.
- When I try to open a notebook, I get this error: Unable to load.
- When I try to open a notebook, I get this error: Error opening notebook. Unable to connect to the Docker environment on the notebook server. Please make sure that the notebook server prerequisites to run Docker have been met.
- When I try to open a notebook, I get an error that the container is not running.
Notebooks
- With ArcGIS Notebook Server using Windows containers, when I run two or more notebooks in the notebook editor that import the torch library or Python libraries that have Torch as a dependency, the import statements fail in all but the first notebook I ran with [WinError 1455] The paging file is too small for this operation to complete. Error loading "C:\ArcGIS_Server\Server\framework\runtime\ArcGIS\bin\Python\envs\arcgispro-py3\lib\site-packages\torch\lib\caffe2_detectron_ops_gpu.dll" or one of its dependencies.
- With ArcGIS Notebook Server using Windows containers, when I run a notebook that imports the mljar-supervised library, the import statement takes a long time or results in a Kernel died error.
- When I run a notebook cell with Python code that uses an ArcGIS Enterprise portal item, the request times out. This happens whenever I run a cell that contains a remote URL.
Installation
Access to notebooks
The SSL certificate configured with the ArcGIS Notebook Server site web adaptor is not trusted by your web browser. Ensure that you have a CA-signed certificate configured and HTTPS is enabled on your site.
If you're using a self-signed certificate in a development or staging environment, open the URL of your ArcGIS Notebook Server Administrator Directory and add an exception in your web browser to trust the self-signed certificate.
When I try to open a notebook, I get this error: Error opening notebook. Unable to connect to the Docker environment on the notebook server. Please make sure that the notebook server prerequisites to run Docker have been met.
One or more of the prerequisite settings that allow the Docker Engine component to work with ArcGIS Notebook Server have not been configured. Refer to the following topics in the installation guide for more information:
When you verify that all necessary settings have been configured, run the following in a command prompt to confirm that Docker is running on your ArcGIS Notebook Server machine:
docker version
docker run hello-worldIf this error message appears, the container is available but is not in a running or usable state. To make it accessible, you must terminate the container using the Administrator Directory. Ensure that you're terminating the container specified in the error message. Once it's been terminated, have the notebook owner reopen the notebook, which will relaunch the container.
Notebooks
With ArcGIS Notebook Server using Windows containers, when I run two or more notebooks in the notebook editor that import the torch library or Python libraries that have Torch as a dependency, the import statements fail in all but the first notebook I ran with [WinError 1455] The paging file is too small for this operation to complete. Error loading "C:\ArcGIS_Server\Server\framework\runtime\ArcGIS\bin\Python\envs\arcgispro-py3\lib\site-packages\torch\lib\caffe2_detectron_ops_gpu.dll" or one of its dependencies.
This behavior is due to the default maximum paging file size configured for the virtual memory on the Notebook Server machines. Follow these steps to increase the default paging file size and the maximum CPU and memory allotted to a notebook.
Note:
Consult your system administrator for the appropriate paging file size before making these changes.
- On each ArcGIS Notebook Server machine click Start > Settings > System > About > Advanced system settings
- In the Advanced tab of the System Properties dialogue box, click Settings in the Performance section.
- In the Performance Options dialogue box, click to the Advanced tab.
- Click Change in the Virtual memory section.
- In the Virtual memory dialogue box, uncheck Automatically manage paging file size for all drives.
- Select Custom size.
- Enter your Initial size (MB) and Maximum size (MB).
- Click Ok and restart your machine.
Once your machine has restarted, follow these steps in ArcGIS Notebook Server Manager.
- Click Settings > Runtimes.
- Select the runtime you use for running notebooks that import torch and click Edit.
- Update the Max CPU to 4 cores and the Max Memory to 12 GB.
- Click Save to confirm the update.
- Exit ArcGIS Notebook Server Manager.
With ArcGIS Notebook Server using Windows containers, when I run a notebook that imports the mljar-supervised library, the import statement takes a long time or results in a Kernel died error.
This behavior is the result of the mljar-supervised library having many dependencies. Follow these steps to increase the maximum CPU allotted to a notebook in ArcGIS Notebook Server Manager.
- Click Settings > Runtimes.
- Select the runtime you use for running notebooks that import mljar-supervised and click Edit.
- Update Max CPU to 4 cores.
- Click Save to confirm the update.
- Exit ArcGIS Notebook Server Manager.
When I run a notebook cell with Python code that uses an ArcGIS Enterprise portal item, the request times out. This happens whenever I run a cell that contains a remote URL.
The network being used by the Docker containers running in your site is conflicting with your ArcGIS Enterprise network, which blocks the Python code from connecting to the network. Refer to the Docker documentation on configuring networking. When you've configured your network for Docker, run your notebooks again.
When I run the default first notebook cell (including the string gis = GIS("home")), I get a URL error saying Temporary failure in name resolution.
This error can occur when ArcGIS Notebook Server and its Docker component are installed on the same machine as other ArcGIS Enterprise components. It occurs because the default privatePortalUrl property stored in ArcGIS Notebook Server is a shortened version of the fully qualified domain name. This causes a failure when attempting to contact the portal.
The solution is to amend the privatePortalUrl property to be the fully qualified domain name of the ArcGIS Notebook Server site:
- Sign in to the ArcGIS Portal Directory as a member of the default administrator role in your portal. The URL format is https://portal.domain.com:7443/arcgis/portaladmin.
- Click System > Properties > Update Properties.
- On the Update System Properties dialog box, insert a JSON string with the fully qualified domain name of the portal in the following format:
{ "privatePortalUrl": "https://portal.domain.com:7443/arcgis"
