哪个 python 包为 statsmodels 实现了 _representation 和 _kalman_filter？

Question

作为 python 的新手，我第一次使用一些导入设置 Rodeo：

import sys
import pandas as pd
import pylab as pl
import numpy as np
import statsmodels.api as sm

但是import statsmodels一直报错。这是最新的：

>>> import statsmodels.api as sm
ImportError: cannot import name '_representation'

我不确定我是否理解错误。这里缺少哪个包 Rodeo？ cython_blas 是不是少了什么？

Answer 1

您可能有一些不兼容或过时的依赖项版本。

尝试更新依赖项，看看是否有帮助：

pip install statsmodels --upgrade

哪个 python 包为 statsmodels 实现了 _representation 和 _kalman_filter？

Which python package implement _representation and _kalman_filter for statsmodels?

python

statsmodels
