I'm testing out Great Expectations by following this tutorial:

Unfortunately my jupyter notebooks could not open the browser direclty at first, but I was able to fix that behavior by following this thread, which has to do with Jupyter notebook configuration. Unfortunately some other problems persist which require assistance.

  1. When I create an expectation, the data_docs opens on an URL like :

    file:///home/user/workspaces/gx_tutorials/great_expectations/uncommitted/data_docs/local_site/validations/getting_started_expectation_suite_taxi/demo/__none__/20230122T183749.724235Z/3aa0a5a68a2bbe5abd3b08ea9739616c.html

    But this doesn't open since my /home folder isn't on windows, where the browser is installed. So I have to work around it manually everytime by replacing file:/// with file://///wsl.localhost/Ubuntu-20.04/ like this

    file://///wsl.localhost/Ubuntu-20.04/home/user/workspaces/gx_tutorials/great_expectations/uncommitted/data_docs/local_site/validations/getting_started_expectation_suite_taxi/demo/**none**/20230122T181115.325050Z/3aa0a5a68a2bbe5abd3b08ea9739616c.html

  2. When I am able to open the validation results via the relevant jupyter notebook as described in the tutorial page: how to run validation and inspect your validation results, I click on the link to the invalid result and I get a 404, the file does not exist in this directory:

    file://///wsl.localhost/Ubuntu-20.04/home/user/workspaces/gx_tutorials/great_expectations/uncommitted/data_docs/local_site/validations/getting_started_expectation_suite_taxi/demo/20230122-213919-my-run-name-template/20230122T213919.318761Z/444fa93fe34e9e162c5f910bca5b5916.html

    But when I check my directory, this file is there, and I have to rename the 444fa93fe34e9e162c5f910bca5b5916.html to sample.html manually, and open it via Windows' explorer, which is a work around I would like to avoid, and have a permanent solution instead.

Your help would be much appreciated.

For anyone using WSL2, I think the better answer is to install a browser (Chrome or Firefox) there. Good instructions here:

There are other tutorials out there that show how to launch your Windows browser, but they're never going to help with the fact that GX wants to use the Linux /tmp directory.
