Hi @ines,

I was following along the`ner-food-ingredients` tutorial. Installed `prodigy` and `en_core_web_lg` using the following commands in a virtual environment.

```python
python -m pip install ./models/prodigy-1.9.9-cp36.cp37.cp38-cp36m.cp37m.cp38-macosx_10_13_x86_64.whl

python -m spacy download en_core_web_lg 

```

## Command

I came across the same issue when running the following command:

```python
prodigy train ner food_data en_core_web_lg --init-tok2vec ./models/tok2vec_cd8_model289.bin --output ./models/tmp_model --eval-split 0.2

```

## Output

```python
Traceback (most recent call last):

ValueError: could not broadcast input array from shape (128) into shape (96)

```

## Other details

```python
pip show spacy
Name: spacy
Version: 2.2.4
Location: /Users/raqib/nlp/ner-food-ingredients/.venv/lib/python3.8/site-packages
Required-by: prodigy, en-core-web-lg

```

```python
pip show en-core-web-lg
Name: en-core-web-lg
Version: 2.2.0
Location: /Users/raqib/nlp/ner-food-ingredients/.venv/lib/python3.8/site-packages
Requires: spacy

```

```python
pip show prodigy
Name: prodigy
Version: 1.9.9
Location: /Users/raqib/nlp/ner-food-ingredients/.venv/lib/python3.8/site-packages

```

## What have I tried thus far:

1. Tried version `2.2.5` and `2.2.0` of `en-core-web-lg`
2. Tried changing python version from `3.8` to `3.7`.

Would appreciate any pointers.
