我正在训练一个模型,以使用Facebook Prophet模型预测能耗值。 但是在使用pickle保存模型时出现此错误:
TypeError Traceback (most recent call last)
<ipython-input-54-9ef2990419d8> in <module>
1 with open('forecast_model.pckl', 'wb') as fout:
----> 2 pickle.dump(model, fout)
TypeError: can't pickle _thread.RLock objects
代码:
from fbprophet import Prophet
import pickle
model = Prophet()
model.fit(df)
with open('forecast_model.pkl', 'wb') as fout: <== Error coming here
pickle.dump(model, fout)
df.head()

[EDIT] 解决方案链接:https://github.com/facebook/prophet/issues/1361:
下面给出的代码对我有用
model = Prophet()
model.stan_backend.logger = None
with open('test.pickle', 'wb') as f:
pickle.dump(m, f)
答案 0 :(得分:1)
我遇到了同样的问题。 我重新安装了fbprophet 0.5版,例如
pip install -U fbprophet==0.5
如果您不需要最新版本:0.6,可以尝试一下。
