2 Slow Test Failures That Sam Can Fix
Both related to fp16

1)
```
        if torch.cuda.is_available():
            testargs += ["--fp16", "--gpus=1"]
    
        with patch.object(sys, "argv", testargs):
>           result = run_pl_glue.main()
```


2)
```
examples/seq2seq/test_bash_script.py::test_train_mbart_cc25_enro_script
```
needs rerun/ cannot use fp16
