Hello, I am trying to train a model using the `en_core_web_lg` model as the `--base-model`.

Here is the code I am using:

```python
prodigy train new_model --textcat-multilabel annotated_tweets --eval-split 0.2 --base-model en_core_web_lg

```

I am using an Anaconda environment set up with the following commands:

```python
conda create -n prodigy python=3.10.4
conda activate test_env

pip install prodigy -f https://XXX-XXX-XXXX-XXX@download.prodi.gy

#I have tried both of the following to download the model (both seem to give the same error)
python -m spacy download en_core_web_lg
conda install -c conda-forge spacy-model-en_core_web_lg 

```

This is the error that I get:

```python
ℹ Using CPU

========================= Generating Prodigy config =========================
ℹ Auto-generating config with spaCy
ℹ Using config from base model
✔ Generated training config

=========================== Initializing pipeline ===========================
✘ Config validation error
Bad value substitution: option 'width' in section 'components.textcat_multilabel.model.tok2vec' contains an interpolation key 'components.tok2vec.model.encode.width' which is not a valid option name. Raw value: '${components.tok2vec.model.encode.width}'

```

I couldn't find much on the internet about this error, so I thought I'd ask if you have any ideas as to how to solve this. Any thoughts appreciated - thanks!

Hello @cbjrobertson,

thank you for your question.  
It seems that you have a similar problem as described here: [Unable to train textcat model using en\_core\_web\_md as a base model](https://support.prodi.gy/t/unable-to-train-textcat-model-using-en-core-web-md-as-a-base-model/5953)  
The solution my colleague Vincent found was to use a spacy-config file as workaround, see: [Unable to train textcat model using en\_core\_web\_md as a base model - #4 by koaning](https://support.prodi.gy/t/unable-to-train-textcat-model-using-en-core-web-md-as-a-base-model/5953/4)  
For your problem, you would have to change the model from `en_core_web_md` to `en_core_web_lg`.

Can you try this out? Maybe this works for you too.
