ADD requires at least two arguments

[palpen]

I'm getting an error when I ran bash setup_server.sh that appears to be related to building the docker image for the DALLEePaperFrame/server/x86/Dockerfile.export dockerfile:

Error response from daemon: dockerfile parse error line 9: ADD requires at least two
arguments, but only one was provided. Destination could not be determined.

I believe it is referring to this line

DALLEePaperFrame/server/x86/Dockerfile.export

Line 9 in ddf894e

ADD extract_onnx_models.py

I'm far from a Docker expert so I'm not sure exactly how to fix this. Any suggestions?
