GPU support - cuda 11.1 - TypeError: Unsupported type <class 'numpy.ndarray'>

Example:
``` python
import spacy

spacy.require_gpu()
>> True

nlp = spacy.load("en_core_web_sm")
doc = nlp("this is my example text")
print(doc)
>> this is my example text

import neuralcoref
neuralcoref.add_to_pipe(nlp)
>>

doc = nlp("this is my example text")
>> Traceback (most recent call last):

```

Everything works fine if I run this without `spacy.require_gpu()`.
