"Error: Failed to pull data from the cloud" when pulled data is a directory

When pulling data from remote storage, I execute the following command: dvc pull train.dvc

with content of the file: train.dvc

cmd: python train.py
deps:
- md5: 454410a0e96e7c268914287865e94bbc
  path: data/dataset.csv
md5: c1b4f121d34f4dbd426089bbbec26d3c
outs:
- cache: true
  md5: 9f1f44cc23e76e794f7423d4a76147a3.dir
  path: outputs/models/

Then obtain the following error:

It seems that it happens because of the output of train.dvc is a directory. It works fine when it’s a file.

some infos: dvc==0.21.0 installed with pip macOS 10.14

@efiop , Seems like the issue might be because unintentionally my Mac system create an empty file called Icon and DVC was tracking that but gdrive failed to track it as it was empty & hence during dvc pull DVC could not pull the Icon file as it was not in my gdrive remote. Let me test this and see if I am correct.
