  The flux of low energy atmospheric neutrinos (E_nu ~ 4 GeV) has been studied
with the MACRO detector at Gran Sasso by detecting nu_mu interactions inside
the apparatus, and by upward-going stopping muons. The updated analysis of the
data collected until now with the complete apparatus will be presented. The
results show a deficit of the measured number of events in an uniform way over
the whole zenith angle with respect to Monte Carlo predictions. The deficit and
the angular distributions, when interpreted in terms of neutrino oscillations,
are consistent with the MACRO results on the much higher energy upward
throughgoing muons (E_nu ~ 100 GeV).
