示例1: test_override_n_changepoints
# 需要导入模块: from fbprophet import Prophet [as 别名]
# 或者: from fbprophet.Prophet import set_changepoints [as 别名]
def test_override_n_changepoints(self):
m = Prophet()
history = DATA.head(20).copy()
history = m.setup_dataframe(history, initialize_scales=True)
m.history = history
m.set_changepoints()
self.assertEqual(m.n_changepoints, 15)
cp = m.changepoints_t
self.assertEqual(cp.shape[0], 15)示例2: test_get_zero_changepoints
# 需要导入模块: from fbprophet import Prophet [as 别名]
# 或者: from fbprophet.Prophet import set_changepoints [as 别名]
def test_get_zero_changepoints(self):
m = Prophet(n_changepoints=0)
N = DATA.shape[0]
history = DATA.head(N // 2).copy()
history = m.setup_dataframe(history, initialize_scales=True)
m.history = history
m.set_changepoints()
cp = m.changepoints_t
self.assertEqual(cp.shape[0], 1)
self.assertEqual(cp[0], 0)示例3: test_get_changepoints
