我需要你的帮助。关于statsmodel.api和statsmodel.formula.api，Dll加载失败：Dll加载失败找不到指定的过程

Question

我要执行的代码是这样的

import numpy as np
import statsmodels.api as statm
import statsmodels.formula.api as statfa
import pandas as pd
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
...
...

正在执行

在康达环境。。。 安装完成（numpy、statsmodels、pandas、matplotlib） 但是 conda安装statsmodels.api

和conda安装statsmodels.formula.api。。。我也是

1. 为什么不呢？导入statsmodels.api，导入statsmodels.formula.api
2. 为什么不呢？conda安装statsmodels.api，导入statsmodels.formula.api

Answer 1

我找到了解决办法

这真是个简单的问题

1. 康达移除statsmodels
2. pip安装statsmodels

我受这个问题折磨了三天
