1. An error prediction apparatus comprising a control arithmetic unit including at least one processor and at least one memory, wherein the control arithmetic unit configured to:
receive environment data of a surveying site in which a surveying instrument is installed;
to input the environment data of the surveying site into an error prediction model and predict a predicted error that occurs in a surveying result obtained by the surveying instrument under an environment of the surveying site; and
to create display data for displaying the predicted error when the predicted error exceeds an allowable value, wherein
the error prediction model is a learned model created by machine learning for a surveying instrument of the same model as that of the surveying instrument by using a set of the environment data indicating an environment of the time of surveying and error data in a surveying result as teacher data.
