Cannot create a new project in Dataflow Complier Studio

General
1

I have set up a new Ubuntu 20.4 environment (x86) with 32 GBy Ram and 20 GBy disk (AWS r5.xlarge) and installed DFC 3.31.0 on Python 3.10.12 (via virtualenv).

I run DFC Studio using this command:

hailo dfc-studio

Then I get the screen “Create your first project”, enter my project name, and click “Create Project”. No project is created, and I get an indicator in the upper right “Project was not created”. No other error messages show in terminal were I ran Studio.

Here is the terminal output:

I have plenty of available disk space:

My user is umbuntu and I run Studio it it’s home directory.

Got this to work, and documenting for future reference by the community…

I switched to using the docker image, but get the same error message.

Eventually, I resolved the issue by inspecting the browser console logs:

Studio is using local file access, and showDirectoryPicker is only available in a secure environment under Chrome. There is a Chrome option --unsafely-treat-insecure-origin-as-secure that allows one to specify a origin, and then Studio works.

On Mac OS the command line looks like this:

open -a "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --args --user-data-dir=/tmp/chrome-dev-profile --unsafely-treat-insecure-origin-as-secure=http://<hostname>:3000
