Python：Anaconda安装虚拟环境到指定路径
https://www.cnblogs.com/lemonbit/p/7068091.html
Problem with tensorflow, TF_SessionRun_wrapper: expected all values in input dict to be ndarray
I fixed it by upgrading
- the
numpypackage to (1.16.2). - tensorflow to 1.13.1 ,
- Python to 3.6.8 ,
- tensorflow-gpu to 1.13.1
Does not work with version 2.0.A.
Sorry for the late reply. Turns out there were some incompatible versions with some dependencies. This is not a bug in the TF codebase.
I did a complete upgrade on my anaconda installation and that fixed the problem.
Python Packaging tools not found.Install packaging tools：
要安装pip和setuptools
-
先给系统安装
easy_install和pip（推荐）。 -
使用
virtualenv创建一个虚拟环境venv。 -
设置
Pycharm的解释环境为venv里面的python。
Navigator Error：
Main Error：expected str, bytes or os.PathLike object, not NoneType
