能正确安装talib了，但是调用是报错了，是不是numpy版本不对？ tqsdk已经自带了numpy，是不是版本不对？
C:\Users\Administrator>pip install ta-lib

C:\Users\Administrator>pip install numpy

如何安装talib？
- 下载对应的TA_Lib.whl文件，保存到\Scripts文件夹。
选择与系统版本、Python版本对应的文件，如TA_Lib‑0.4.10‑cp36‑cp36m‑win_amd64.whl 适用于Windows64位系统, Python3.6版本。
- 安装TA_Lib，运行命令提示符，在Python的Scripts目录下安装wheel，注意输入的.whl文件名与原文件保持一致
- C:\Python\Scripts\pip install TA_Lib‑xxxxx‑cpxxx‑cpxxx‑winxx.whl
- 检验TA_Lib是否安装成功
复制代码
- import talib
没有报错则说明安装成功。
希望tqsdk新增LINEARREG_SLOPE和FORECAST方法，谢谢
