Hi everyone,
i tried to install the package via pip. But i get the following error :

BUG: Exceptions are not explicitly raised in python when validating output.

htnorm/pyhtnorm/_htnorm.pyx

Lines 98 to 109 in ef1f2e4

 cdef inline void validate_return_info(int info): 

 if info == HTNORM_ALLOC_ERROR: 

 raise MemoryError("Not enough memory to allocate resources.") 

 elif info < 0: 

 raise ValueError("Possible illegal value in one of the inputs.") 

 elif info > 0: 

 raise ValueError( 

 f"""Either the leading minor of the {info}'th order is not 

  positive definite (meaning the covariance matrix is also not 

  positive definite), or factorization of one of the inputs 

  returned a `U` with a zero in the {info}'th diagonal.""" 

 )

Since this cython function has void return type, the raised exception is not propagated properly and thus gets treated as a warning.

To remedy this, the function should return an int. A value of zero when everything checks out and probably a -1 otherwise.
