# pyblp.exceptions.SyntheticPricesConvergenceError¶

class pyblp.exceptions.SyntheticPricesConvergenceError

The fixed point computation of synthetic prices failed to converge.

This problem can sometimes be mitigated by increasing the maximum number of fixed point iterations, increasing the fixed point tolerance, configuring other iteration settings, or making sure the specified parameters are reasonable. For example, the parameters on prices should generally imply a downward sloping demand curve.
