我正在使用 conda(通过 YAML 创建的 env)+ pip 在我的 Linux Mint 盒子上设置 Tensorflow v1.13.1 环境。设置后,每当我尝试导入时tf.estimator
我收到AttributeError
标题中描述:
AttributeError: module 'tensorflow' has no attribute 'estimator'
- 我没有在 conda 环境之外(或 pip 上)安装任何版本的 TF。
- 我确实以相同的方式设置了另一个 conda 环境,但使用 Tensorflow 2.0 alpha,它可以导入
tf.estimator
正好。
- 我尝试过删除环境并重新构建它
- 我尝试过重新启动:(
- 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:

从相关环境内部:

pip 19.0.3 from /home/cjs/.local/lib/python3.7/site-packages/pip (python 3.7)
这是该问题的一个最小示例。正如您所看到的,这只发生在调用 tf.estimator 的地方,所有其他 Tensorflow 属性都按预期运行:

UPDATE
As per 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 NVIDIA 驱动程序更新至 v418,并且能够将 conda 版本更新至 4.16.14。我将上面显示的environment.yml更新为cudatoolkit==10.1
,但我似乎不知道如何实际安装它。
My numba -s
输出包括这一部分,这让我认为从一开始的整个问题就是 cuda 找不到我的 GPU(或者无法连接到它?)。
__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 问题的原因是我更新 GPU 驱动程序后没有重新启动(废话)。
不过,在这方面还没有完全摆脱困境。新问题如下:
