ArcGIS Notebook Server

Question 1

When loading notebook runtime images, I get the error no space left on device, despite having room left on the drive where ArcGIS Notebook Server and Docker are installed.

Answer

Check the Docker desktop settings for advanced resource allocation and verify that there is a sufficient disk image size allocated for the disk image location. Increase the disk space allocated and retry loading the notebook runtime images.

Question 2

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.

Answer

If your ArcGIS Web Adaptor runs on an IIS web server, this error occurs when the WebSocket protocol is disabled on that machine. Starting at 10.8, ArcGIS Web Adaptor automatically enables the WebSocket protocol on IIS web servers; you must not disable the protocol.

Question 3

When I try to open a notebook, I get this error: Unable to load.

Answer

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.

Question 4

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.

Answer

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-world

Question 5

When I try to open a notebook, I get an error that the container is not running.

Answer

If 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.

Question 6

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.

Answer

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.

Question 7

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.

Answer

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.

Question 8

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.

Answer

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.

Question 9

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.

Answer

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" }
```

Question 10

When I run the default first notebook cell (including the string gis = GIS("home")), I get an error stating: ConnectionError: A connection error has occurred: HTTPSConnectionPool(host=,port=443): Max retires exceeded with url: /portal/sharing/rest/info=fjson (caused by NewConnectionError ('urllib3.connection.HTTPSConnection object at 0x7f672e592b0>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution'))

Answer

When deploying Docker containers, name servers are copied from the resolv.conf file of the host machine. This can result in errors on setups that use public DNS servers for machines, as the Docker containers need to be able to resolve internal DNS names.

The solution is to configure dockerExtraHosts in the ArcGIS Notebook Server system properties:

Open the URL of your ArcGIS Notebook Server Administrator Directory.
Click System > Properties > Update Properties
In the Update System Properties dialogue box, insert a JSON string of the host names and IP addresses in the following format:
```
{ "dockerExtraHosts": [ { "hostname" : "<host name>", "ip" : "12.34.56.78" } ] }
```
