I get the following error at this step:

I think the problem is that when `ReLU.forward().compute()` is called, then
it tries to execute:
```
source("C:\Users\rahul\IdeaProjects\AMLS\systemds\scripts\nn\layers\relu.dml")
as relu
V1=read('./tmp/V1',rows=6,cols=1);
V2=relu::forward(X=V1);
write(V2, './tmp');
```
and this might be failing because of the backslashes in the path.
@Baunsgaard Any idea on how I can fix this?
