Vectorization and Code Insights
You can print the results collected in the CLI and save them to a

For example, to generate the Survey report:
advisor --report=survey --project-dir=./advi
You should see a similar result:

The result is also saved into a text file
You can also generate a report with the data from all analyses run and save it to a CSV file with the

To open the project in GUI, you can run the following command:

You first see a Vectorization Summary report that includes the overall information about vectorized and not vectorized loops/functions in your code and the vectorization efficiency, including:

Save a Read-only Snapshot
A snapshot is a read-only copy of a project result, which you can view at any time. To save an active project result as a read-only snapshot:
