解决dtypes.py:513: FutureWarning:...系列问题【TensorFlow】-CFANZ编程社区

前情提要

我的TensorFlow版本是2.4.0，python环境是3.8.19

问题

在训练模型时出现以下报错：

D:\anaconda3\envs\env_tf\lib\site-packages\tensorflow\python\framework\dtypes.py:513: FutureWarning: In the future `np.object` will be defined as the corresponding NumPy scalar.

`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

解决过程

方案一：在报错中ctrl点击报错位置定位到你报错的源代码中，我定位到的是dtypes.py这个源文件里，然后将所有np.object的地方都改成object，如果运行后又报错dtypes.py:516…的问题的话，依照同样的方法定位到源文件中，将所有np.bool的位置都改成np.bool_，亲测改后不会再报这个错，出现其他情况详见方案二

方案二：百度后发现是numpy版本问题，需要更新，遂更新至最新版本（能方案一就不方案二，因为你也不知道你更新后会不会出现下文所说的包版本冲突！！）

pip install --upgrade numpy

如果更新完后你的代码可以运行，那恭喜你不用踩后面的坑了（✿✿ヽ(°▽°)ノ✿）

更新完numpy后，虽说安装成功，但出现了如下信息ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. tensorboard 2.10.0 requires protobuf<3.20,>=3.9.2, but you have protobuf 3.20.3 which is incompatible. tensorflow 2.3.0 requires gast==0.3.3, but you have gast 0.4.0 which is incompatible. tensorflow 2.3.0 requires numpy<1.19.0,>=1.16.0, but you have numpy 1.24.4 which is incompatible. tensorflow 2.3.0 requires scipy==1.4.1, but you have scipy 1.10.1 which is incompatible. tensorflow 2.3.0 requires tensorflow-estimator<2.4.0,>=2.3.0, but you have tensorflow-estimator 2.6.0 which is incompatible.

这里的问题其实就是，我们安装的包版本互相冲突了。我就开始根据报错提示，把我的包用如下命令更换成指定的适配的包版本（-i后加个清华源下载更迅速！）
【但在这一步，可能有的朋友就会发现了！这个过程中你的numpy包是很有可能把版本号给降低，即安装回旧版本的！！！】

pip install 包名==版本号 -i https://pypi.tuna.tsinghua.edu.cn/simple

如果更新后没有报错，恭喜你又不用踩后面的坑了！

在我更新完所有的包后，这时终端也没有其他的报错信息了，我重新运行我的训练代码，结果出现了以下问题：
