I just installed the latest psi4 (1.4rc2.dev102) with python bindings (anconda3, python 3.6). I wanted to perform a dct calculation on a simple molecule but get the following error after the first scf:

input:

```
import psi4
R = 0.7414
h2 = psi4.geometry("""
0 1
H
H 1 {0}
""".format(R)
)
psi4.set_options({"SCF_TYPE": "DF",
"BASIS": "cc-pvdz" ,
"DF_BASIS_DCT": "cc-pvdz"})
psi4.energy('dct')
```

truncated output:
