Hi all, I have Dagster running on a VM and connected as Agent to Dagster Cloud. I'm trying to add a code location of a repository I cloned inside

dagster_home

called

my_project

however I get the following error:

Exception: Can not import module dagster from path ./dagster_home/my_project/dagster, unable to load spec.

Here's the location YAML I've defined via Cloud UI:

location_name: my_project
code_source:
  python_file: ./dagster_home/my_project/dagster

What am I missing?

Hi Charles - a couple of ideas to try: Firstly - typically a python file would end in .py - so if dagster is a folder rather than a file you may want to use

package_name

rather than

python_file

as your key. the first thing I would try is renaming your folder to something other than dagster, as I've seen python get very confused when determining if an import was a local module with the same name as an installed module (for example, you'll often have a bad time if you try to load a file called random.py or math.py since those are built-in python packages). The next thing I'd try is seeing whether running 'python ./dagster_home/my_project/dagster' (or whatever the new filename is) - or

python -m <your folder>

if it's a folder/python module) is able to run your code without any issues, that will typically surface any import-related issues which seems to be what's happening here.

Thank you Daniel that's very helpful! In the Dagit documentation, I read this:

Every code location must set the

code_source:

key to either

python_file:

or

package_name:

to specify where to find your code.

But it's not clear to me what kind of file Dagster is looking for? ie; should the

.py

file reference a

resopository

object such as this one? Or something else?

Ah sorry, where I said python_module I should have said package_name, my mistake

No worries, I edited my follow-up question too.

Ah sorry, I misunderstood your comment
