“”’norm’”” attributeError using e.g. unwa beta 5e model in UVR

- a) Ensure you installed UVR Roformer patch (5.6.1), and you're not using the old 5.6 version (but 5.6.1 is reported once you open the app)

 

b) You could pick wrong model architecture in Install model option (so not Roformer, and generally v1), or haven’t turned on “Roformer model” option during importing the model into UVR (option present in the older beta versions).

You can go to the bottom of the models list and pick “Edit Model” to change it.

 

c) Alternatively the following might help in some cases:

“Edit the yaml file [of the model] from this -

 

training:

  instruments:

  - vocals

  - other

  target_instrument: vocals

  use_amp: True

 

to this -

 

training:

  instruments:

  - Vocals

  - Instrumental

  target_instrument: Vocals

  use_amp: True

E.g. BS-Roformer_LargeV1 is stuck on 5%

- Decrease chunk_size to 112455 (new patches)
(pre-10# patches) “Go to MDX settings, MX23C specific, turn off default segment size and use segment size 256, it's probably filling up your VRAM”
The setting resets itself. You should be able to set it permanently in the yaml configuration file of the model at the bottom (dim_t parameter).
It might be required for AMD/Intel 4GB VRAM GPUs (or potentially even 201, although it was using Rofo patch #2).

 

Q: Is there a way to reset which yaml file to use? I chose the incorrect yaml file for a particular ckpt file, and now I cannot change it

A: Go to models list>Edit Model Config>Change parameters and choose the yaml from the list.

Or go to Ultimate Vocal Remover\models\MDX_Net_Models\model_data and if it was done just now, the last modified yaml in this folder will be the one corresponding to your model. You can just open that json, and edit it to write the config name located in mdx_c_configs you want to use with that model. You should find proper hashed yaml by the saved model of your choice, but if you really feel lost, you can delete all hashed yamls, so you’ll need to go through the process of choosing configs for all custom MDX and Roformer models, but remember to not delete "model_data.json" and "model_name_mapper.json" as they cover models added to Download Center or written to be recognized automatically by UVR, so it’s rather not a place you look for. Also, you can decode hashed json names corresponding to specific models here.

 

Layers error (for issues with Unwa 400MB model)

-“First make sure you're running the latest patch. If you're on the latest patch, It might be trying to associate with an incompatible yaml”, but resetting the parameters below might be enough.

 

Go into the mdx_c_configs folder

Find and delete BS_Inst_EXP_VRL.yaml

Go back into the "Download Center"

Select "MDX-Net" and give it a moment.

Close the Download Center and try again.

 

If that doesn't work, you might have a previous json model file that's interfering:

 

Select the model in the MDX-Net model menu

Then select "Edit Model Config"

From the popup, click "Reset Parameters"” - Anjok
