anaconda安装tensorflow遇到的一个错误

笔者在conda环境 python=3.8安装tensorflow-2.5.0，因为这个2.5.0版本与笔者的CUDA版本是匹配的，结果安装好后，在python环境里执行“import tensorflow as tf”就报了一大堆错误：

`np.object` was a deprecated alias for the builtin `object`. To avoid this error in existing code, use `object` by itself. Doing this will not modify any behavior and is safe.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

从错误的提示看来是numpy版本不匹配，这里的numpy版本是1.24.3，有点高了。于是降级也不成，因为numpy被一大堆安装包所依赖，删除numpy会删除几乎整个tensorflow环境。在网上搜索了一番，于是尝试降低python版本为3.6，再安装tensorflow-2.5.0，结果import tensorflow时，直接报python版本不匹配，于是在python版本3.7下再安装tensorflow-2.5.0，导入tensorflow时，没有报错，整个过程简直就是恶作剧一场！半天时间就这么没了。
