arch包

直接pycharm下载，科学一下最好

使用教程(4条消息) 关于Python的ARCH包（二）liuxoxo的博客-CSDN博客python arch

from statsmodels.tsa.arima_model import ARMA
from statsmodels.graphics.tsaplots import plot_acf,plot_p
from statsmodels.tsa import stattools
from arch import arch_model
from datetime import datetime
import warnings
warnings.filterwarnings("ignore")
path="./data/玉米期货.xLsx"
conda install -c bashtage arch

​报错是因为没有arch模块
conda install -c bashtage arch
conda install -c conda-forge arch-py

报错

版本绍兼容性

(一) 如何在Python3.8上安装TensorFlow (Mac版本) - 七弹指的树 - 博客园 (cnblogs.com)

原理：因为python=3.8是最新版本，相应的TensorFlow 还没能及时更新，需要自己下载安装TensorFlow2

UnsatisfiableError: The following specifications were foundto be incompatible with the existing python installation in your environment:

Specifications:规格规范；详细说明

• arch -> python[version='2.7.|3.5.|3.6.|>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|3.4.|3.3.*']

Your python: python=3.9

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

conda create -n env_name python=3.8
conda activate env_name
conda install pandas scikit-learn matplotlib notebookpip3 install --user --upgrade tensorflow  #安装最新版本的tensorflow
