We switched all model paths to be absolute in #5900. In hindsight, this is a mistake, because it makes the `models_dir` non-portable.
This change reverts to the previous model pathing:
- Invoke-managed models (in the `models_dir`) are stored with relative paths
- Non-invoke-managed models (outside the `models_dir`, i.e. in-place installed models) still have absolute paths.
## Why absolute paths make things non-portable
Let's say my `models_dir` is `/media/rhino/invokeai/models/`. In the DB, all model paths will be absolute children of this path, like this:
- `/media/rhino/invokeai/models/sd-1/main/model1.ckpt`
I want to change my `models_dir` to `/home/bat/invokeai/models/`. I update my `invokeai.yaml` file and physically move the files to that directory.
On startup, the app checks for missing models. Because all of my model paths were absolute, they now point to a nonexistent path. All models are broken.
There are a couple options to recover from this situation, neither of which are reasonable:
1. The user must manually update every model's path. Unacceptable UX.
2. On startup, we check for missing models. For each missing model, we compare its path with the last-known models dir. If there is a match, we replace that portion of the path with the new models dir. Then we re-check to see if the path exists. If it does, we update the models DB entry. Brittle and requires a new DB entry for last-known models dir.
It's better to use relative paths for Invoke-managed models.
The seamless logic errors when a second GPU is selected. I don't understand why, but a workaround is to skip the model patching when there there are no seamless axes specified.
This is also just a good practice regardless - don't patch the model unless we need to. Probably a negligible perf impact.
Closes#6010
These two changes are interrelated.
## Autoimport
The autoimport feature can be easily replicated using the scan folder tab in the model manager. Removing the implicit autoimport reduces surface area and unifies all model installation into the UI.
This functionality is removed, and the `autoimport_dir` config setting is removed.
## Startup model dir scanning
We scanned the invoke-managed models dir on startup and took certain actions:
- Register orphaned model files
- Remove model records from the db when the model path doesn't exist
### Orphaned model files
We should never have orphaned model files during normal use - we manage the models directory, and we only delete files when the user requests it.
During testing or development, when a fresh DB or memory DB is used, we could end up with orphaned models that should be registered.
Instead of always scanning for orphaned models and registering them, we now only do the scan if the new `scan_models_on_startup` config flag is set.
The description for this setting indicates it is intended for use for testing only.
### Remove records for missing model files
This functionality could unexpectedly wipe models from the db.
For example, if your models dir was on external media, and that media was inaccessible during startup, the scan would see all your models as missing and delete them from the db.
The "proactive" scan is removed. Instead, we will scan for missing models and log a warning if we find a model whose path doesn't exist. No possibility for data loss.
I had added this because I mistakenly believed the HF token was required to download HF models.
Turns out this is not the case, and the vast majority of HF models do not need the API token to download.
"Normal" models have 4 in-channels, while "Depth" models have 5 and "Inpaint" models have 9.
We need to explicitly tell diffusers the channel count when converting models.
Closes #6058
It's possible for a model's state dict to have integer keys, though we do not actually support such models.
As part of probing, we call `key.startswith(...)` on the state dict keys. This raises an `AttributeError` for integer keys.
This logic is in `invokeai/backend/model_manager/probe.py:get_model_type_from_checkpoint`
To fix this, we can cast the keys to strings first. The models w/ integer keys will still fail to be probed, but we'll get a `InvalidModelConfigException` instead of `AttributeError`.
Closes#6044
Previously we only handled expected error types. If a different error was raised, the install job would end up in an unexpected state where it has failed and isn't doing anything, but its status is still running.
This indirectly prevents the installer threads from exiting - they are waiting for all jobs to be completed, including the failed-but-still-running job.
We need to handle any error here to prevent this.
Updating should always be done via the installer. We initially planned to only deprecate the updater, but given the scale of changes for v4, there's no point in waiting to remove it entirely.
Loading default workflows sometimes requires we mutate the workflow object in order to change the category or ID of the workflow.
This happens in `invokeai/frontend/web/src/features/nodes/util/workflow/validateWorkflow.ts`
The data we get back from the query hooks is frozen and sealed by redux, because they are part of redux state. We need to clone the workflow before operating on it.
It's not clear how this ever worked in the past, because redux state has always been frozen and sealed.
Add `extra="forbid"` to the default settings models.
Closes#6035.
Pydantic has some quirks related to unions. This affected how the union of default settings was evaluated. See https://github.com/pydantic/pydantic/issues/9095 for a detailed description of the behaviour that this change addresses.
