但在拟合模型时出现错误“AttributeError: 'StanModel' object has no attribute 'fit_class'”
谁能帮我解决这个错误
尝试加载模型时也低于警告
model = Prophet()
WARNING:pystan:No module named 'stanfit4anon_model_f5236004a3fd5b8429270d00efcc0cf9_4174861822198299618'
WARNING:pystan:Something went wrong while unpickling the StanModel. Consider recompiling.
【问题讨论】：
-
尝试重新安装第一个 pystan，然后使用 --no-cache 重新安装 fbprophet。
-
@AdamStrauss 我尝试重新安装 pystan 但无法正常工作。尝试加载模型时也会收到警告，并在原始问题中添加了此内容。是不是因为生成 StanModel 泡菜的版本问题。
-
@AdamStrauss 我尝试从 Anaconda 提示符“conda install -c conda-forge fbprophet”安装，并且能够拟合模型并从 python 运行预测。但仍然不确定之前的问题是什么，为什么我之前收到错误。
