Take this example:
```
a = DataFrame(a =["a","b","c"], b=[1,2,3])
b = ["a","a","b"]
Xover, yover = random_oversample(a, b)
```
This fails because ` ScientificTypes.schema(X).scitypes` fai…

Dear Hypre Developers,
I am currently trying to solve the curl-curl formulation for the eddy current formulation.
The method I would like to use is described e.g. in http://lsec.cc.ac.cn/~zmchen/p…
