我需要你的帮助。关于statsmodel.api & statsmodel.formula.api , Dll load failed : dll load failed 找不到指定程序

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 conda 环境中... 安装完成（numpy、statsmodels、pandas、matplotlib） 但 conda 安装 statsmodels.api

并且 conda 也安装 statsmodels.formula.api...！

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。

这真的是一个简单的问题。

1. conda 删除 statsmodels
2. pip install statsmodels

我被这个问题困扰了三天。
