@ancient-wolf-19325 when I run pyflyte run --remote, is it packaging my local environment or rebuilding a new one?

When you run

pyflyte run --remote

, Flyte does not package your entire local environment. Instead, it "fast-registers" your code by packaging the specified workflow file (and, if needed, its imported modules) into a tarball and injects it into the container image running on the Flyte cluster. The environment (dependencies, Python version, etc.) is determined by the container image specified for the task, not your local environment. If you want to include additional dependencies or files, you must specify them in your Docker image, requirements file, or use options like

--copy-all

or

--include

for targeted inclusion during fast registration. The local environment is not automatically replicated in the remote execution environment—only your code and explicitly included files are sent; the base environment is defined by the image used in the cluster execution context. For more details, see the official documentation on registering workflows and fast registration and the ImageSpec documentation. Would you like a step-by-step breakdown of how the packaging and environment selection works?

@ancient-wolf-19325 is it fetching the dependencies from my local env or is it baking it into the docker image based on my imagespec?

It is baking dependencies into the Docker image based on your ImageSpec, not fetching them from your local environment. When you use an ImageSpec, Flyte builds a new container image with the specified dependencies (e.g., Python packages, APT packages) and uses that image to run your tasks; your local environment's installed packages are not automatically included unless you explicitly specify them in the ImageSpec or requirements file (ImageSpec documentation). Would you like more detail on how to specify dependencies or how the image build process works?
