TensorFlow 错误“没有名为 'tensorflow_core.estimator' 的模块”

Question

我使用以下 .yml 文件在 conda 中构建了一个新环境：

名称：py37 频道：

• conda-forge
• 默认依赖项：
• python=3.7.7
• cartopy=0.18.0
• earthengine-api=0.1.221
• flake8=3.8.1
• jupyterlab=2.1.2
• jupyter_contrib_nbextensions=0.5.1
• matplotlib=3.2.1
• mypy=0.770
• nb_conda=2.2.1 # 可选，对于在 Jupyter 笔记本中运行 R 很有用
• numpy=1.18.4
• 熊猫=1.0.3
• 枕头=7.1.2
• scikit-learn=0.23.0
• scipy=1.4.1
• seaborn=0.10.1
• tqdm=4.46.0
• tensorflow=1.15.0 # 最高只支持 Python 3.7

我现在在 .ipynb 文件中运行以下部分

from pprint import pprint import os import sys

import matplotlib.pyplot as plt import numpy as np import pandas as pd import tensorflow as tf

sys.path.append('../') from preprocessing.helper import get_first_feature_map, get_feature_types from utils.geo_plot import setup_ax

我不断收到以下错误：

我还需要安装其他东西吗？原始的 yml 文件有 - tensorflow==1.15.0 但我更改了它，因为我在 Mac 上运行它并且它不起作用。

感谢任何帮助！

Answer 1

能否请您升级到 tensorflow 2.c [2.7] 并确保 python 和操作系统为 64 位。 你也可以试试：

pip install --upgrade pip
pip uninstall tensorflow
pip install tensorflow

如果错误仍然存​​在：

创建虚拟环境

cd <your project path>

Install virtualenv

pip install virtualenv

创建虚拟环境

virtualenv <envname>

激活环境

Windows Powershell：.\Scripts\activate 带有 Bash 或 zsh 的 Unix：source /bin/activate 然后现在你安装 tensorflow

(<envname>) $ pip install tensorflow

然后成功运行Hello World。

*别忘了每次虚拟环境jupyter、命令行等都需要激活或配置。
