To configure the
UPathIOManager
to use the default Dagster storage path, you don't need to specify a
base_dir
explicitly. The default storage path for the
UPathIOManager
is determined by a hierarchy of possible locations, as described in the documentation: 1. The
base_dir
configuration value of the IO manager, if specified. 2. A
storage/
directory underneath the value for
local_artifact_storage
in your
dagster.yaml
file, if specified. 3. A
storage/
directory underneath the directory that the
DAGSTER_HOME
environment variable points to, if that environment variable is specified. 4. A temporary directory, if none of the above are specified. If you want to use the default Dagster storage path, ensure that you do not provide a
base_dir
when configuring the
UPathIOManager
. Also, make sure that you have set the
DAGSTER_HOME
environment variable to the desired location, or have configured
local_artifact_storage
in your
dagster.yaml
to point to the desired directory. If neither is set, Dagster will use a temporary directory for storage. Here's an example of how you might configure the
UPathIOManager
without specifying a
base_dir
, allowing it to fall back to the default storage path:
Copy code
python from dagster import io_manager, UPathIOManager  @io_manager def default_upath_io_manager():     return UPathIOManager()
By not providing a
base_dir
to
UPathIOManager
, it will follow the hierarchy described above to determine the storage path.
