【问题描述】：
我正在使用 conda（通过 YAML 创建的环境）+ pip 在我的 Linux Mint 机器上设置 Tensorflow v1.13.1 环境。设置后，每当我尝试导入 tf.estimator 时，我都会收到标题中描述的 AttributeError：
AttributeError: module 'tensorflow' has no attribute 'estimator'
- 我没有在 conda 环境之外（或在 pip 上）安装任何版本的 TF。
- 我确实有另一个以相同方式设置的 conda 环境，但使用的是 Tensorflow 2.0 alpha，它可以导入
tf.estimator就好了。 - 我已尝试删除环境并重新构建它
- 我已尝试重新启动 :(
- 由于某种原因，我无法将 conda 更新到 4.6：
$ conda update -n base -c defaults conda

yml 文件如下所示：
dependencies:
- python
- numpy
- tensorflow
- cudatoolkit==9.0
...
从相关环境内部：
$ conda list tensorflow
# packages in environment at /home/cjs/.conda/envs/my-env:
#
# Name Version Build Channel
tensorflow 1.13.1 mkl_py37h54b294f_0
tensorflow-base 1.13.1 mkl_py37h7ce6ba3_0
tensorflow-estimator 1.13.0 py_0
$ pip list | grep tensorflow
tensorflow 1.13.1
tensorflow-estimator 1.13.0
$ which pip
/home/cjs/.conda/envs/my-env/bin/pip
$ conda --version
conda 4.5.11
$ pip --version
pip 19.0.3 from /home/cjs/.local/lib/python3.7/site-packages/pip (python 3.7)
这里是该问题的一个最小示例。如您所见，这只发生在调用 tf.estimator 的情况下，所有其他 Tensorflow 属性都按预期运行：

更新
根据https://docs.nvidia.com/deploy/cuda-compatibility/index.html#binary-compatibility__table-toolkit-driver，我发现我的 nvidia 驱动程序和 cudatoolkit 版本不同步（390.46 与 9.0）。
我现在已将我的 NVIDIA 驱动程序更新到 v418，并且能够将我的 conda 版本更新到 4.16.14。我将上面显示的 environment.yml 更新为cudatoolkit==10.1，但我似乎无法弄清楚如何实际安装它。
我的numba -s 输出包含此部分，这让我从一开始就认为整个问题是 cuda 没有找到我的 GPU（或无法连接到它？）。
__CUDA Information__
Error: CUDA device intialisation problem. Message:Error at driver init:
[100] Call to cuInit results in CUDA_ERROR_NO_DEVICE:
Error class: <class 'numba.cuda.cudadrv.error.CudaSupportError'>
（次要）更新
能够确定 numba 问题的原因是我在更新 GPU 驱动程序后没有重新启动 (duh)。
不过，在这方面并没有完全摆脱困境。新问题如下：

【问题讨论】：
-
你能写你的代码吗？您尝试导入的点。
-
@luca.vercelli 它在我使用它的任何地方，即使在 python 解释器中，当我这样做时 >>>import tensorflow as tf，然后 >>>tf.estimator 它会产生错误
-
好的，但是你能给我们举个例子来说明你是如何使用它的吗？
import tf.estimator给出错误？ -
更新了一些我如何使用它的例子。
-
还有一个疑问。你写“/home/cjs/.conda/envs/my-env”和“/home/cjs/.conda/envs/delreo-env”是故意的吗？还是您正在查看 2 个不同的环境？
