【问题描述】：
系统信息
- Windows10 64 位
- Python 3.8 版
- 尝试使用 conda 和 pip 在 virtualenv 中安装
- CUDA/cuDNN 版本：9.2
- GPU 型号和内存：NVIDIA GeForce GTX 950M
问题 我创建了一个虚拟环境，并在那里开始安装必要的软件包。当我尝试运行使用 tensorflow 的脚本时，它无法导入它。 搜索到这个之后，我尝试将它导入到 jupyter notebook 中，但没有成功。 然后，我尝试将其添加到我的代码中，但它也不起作用： tf.compat.v1.enable_eager_execution( config=None，device_policy=None，execution_mode=None ) 我尝试使用第一个 conda 然后 pip 在该环境中安装 tensorflow。

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.

可能是tensorflow和numpy的兼容性问题？但是文件 'd:\software\anaconda_envs\sweaver\lib\site-packages\numpy-1.19.1.dist-info\RECORD' 实际上并不存在。 我在我的包中搜索，有一个numpy，numpy-1.18.5.dist-info和numpy-1.19.1.dist-info的文件夹，但在最后一个里面，只有两个文件：LICENSES_bundled.txt和REQUESTED .
然后，我删除了文件夹 numpy-1.19.1dist-info 并使用 --user 通过命令行安装了 tensorflow 以允许安装，但它安装在其他地方。 所以，我使用：
import sys
sys.path.append()
在 tensorflow 的每个 py 文件中，但仍然没有工作。还有一个文件（pywrap_tensorflow_internal.py）是空的，说明安装有问题。
希望你能帮助我。
