Receiving "TypeError: sign() missing 1 required positional argument: 'algorithm'" with python PyJWT

So I used the command: ssh-keygen -m PKCS8 -t dsa to generate the following (example) key:

-----BEGIN PRIVATE KEY-----
MIIBSgIBADCCASsGByqGSM44BAEwggEeAoGBAIATtp/DhG2hDIT3DiMIctaxPn/s
FFxbXa4IIytk0b/PDBq9Kv/OeFv54h1L9iSLoNHrsx3dOR+6CyFyfnZT9s0yjpSe

-----END PRIVATE KEY-----

I am attempting to sign data with this key using the following snippet:

import jwt

with open('./id_dsa', 'r') as file:
  key = file.read()
  print(key)
  token = jwt.encode({'some': 'data'}, key, algorithm='EdDSA')

But I am getting this error:

Traceback (most recent call last):
  File "./client.py", line 23, in <module>
    token = jwt.encode({'username': args.username,'publicKey': args.pubKey}, key, algorithm='EdDSA')
  File "/home/walt/angi/auth/lib/python3.8/site-packages/jwt/api_jwt.py", line 63, in encode
    return api_jws.encode(json_payload, key, algorithm, headers, json_encoder)
  File "/home/walt/angi/auth/lib/python3.8/site-packages/jwt/api_jws.py", line 114, in encode
    signature = alg_obj.sign(signing_input, key)
  File "/home/walt/angi/auth/lib/python3.8/site-packages/jwt/algorithms.py", line 578, in sign
    return key.sign(msg)
TypeError: sign() missing 1 required positional argument: 'algorithm'

I am not sure if the key I am generating is incorrect or what else I could be doing wrong.
