Hi,

I cannot connect to database while running the “Getting started” example. How can I fix this? Thank you.

Here is the full trace:

I also have this problem. Is it solved?

I just fixed this problem on my end by creating root_dir passed into try_models. /tmp/run_example/ is C:/tmp/run_example/ in my case. You could also change this parameter to an existing directory.

It works. Thank you so much.

I do not understand the solution. Could you please explain? Thanks

Make sure the root_dir parameter points to a directory that actually exists. In the default example, the value is "/tmp/run_example". On my PC, this points to "C:/tmp/run_example", so I needed to create both the tmp and run_example directories.
