I have cloned and used the LightML package in Julia from [https://github.com/memoiry/lightML.jl](https://github.com/memoiry/lightML.jl) but unfortunately it is showing the error

```julia
ERROR: PyError (:PyObject_Call) <type 'exceptions.ValueError'>
ValueError('could not broadcast input array from shape (10,1) into shape (1,1)',)

```

Can someone say what is the error said about the array…
