I ran into this issue. A hack workaround is importing via an if/else block like follows:

#!/usr/bin/env python3
#myothermodule

if __name__ == '__main__':
    from mymodule import as_int
else:
    from .mymodule import as_int


# Exported function
def add(a, b):
    return as_int(a) + as_int(b)

# Test function for module  
def _test():
    assert add('1', '1') == 2

if __name__ == '__main__':
    _test()
