我还是喜欢使用老版本的python，新版本的python会出现很多依赖包版本太高，又或者太低的现象。这个就是numpy版本太高了。我就安装了numpy==1.18.1

(base) C:\Users\19051\Desktop>conda install -c conda-forge numpy==1.18.1

## Package Plan ##

  environment location: D:\softwareInstall\miniconda3.76

  added / updated specs:
    - numpy==1.18.1


The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    numpy-1.18.1               |   py37h90d3380_1         4.7 MB  conda-forge
    pandas-1.3.1               |   py37h90003fb_0        10.8 MB  conda-forge
    ------------------------------------------------------------
                                           Total:        15.6 MB

The following packages will be DOWNGRADED:

  numpy                               1.21.5-py37h5fa1a60_0 --> 1.18.1-py37h90d3380_1
  pandas                               1.3.5-py37h9386db6_0 --> 1.3.1-py37h90003fb_0

再导入pandas就没有问题了。

PS:另外一种情况解决方式：卸载掉conda安装的包，改使用pip安装就可以了。
