Using conda to update conda, and then anaconda, seems to be working on two different installs of python. And therefore seem to work against one another. For example:

Recommendations for how to deal with this, it's not a huge issue at the moment functionality wise.
This happens because the version of Python in the latest version of Anaconda is 2.7.5. When a new version of Anaconda is released (which should happen this week), this problem will go away.
The anaconda package is a stable set of versions packages of packages that have been tested against one another. Hence, installing or updating anaconda may downgrade Python, because that is the version that is in Anaconda.

At the end of my .bashrc is export PATH="/home/cuiyujie/anaconda3/bin:$PATH". This shows that the path of my anaconda is put to the front, but when I use echo $PATH, the output is /home/cuiyujie/bin:/home/cuiyujie/.local/bin:/home/cuiyujie/anaconda3/bin:/home/cuiyujie /anaconda3/condabin:/usr/local/sbin:. Why did Anaconda run behind again?
When I use the export PATH="/home/cuiyujie/anaconda3/bin:$PATH command directly in the terminal.
echo $PATH is
/home/cuiyujie/anaconda3/bin:/home/cuiyujie/bin:/home/cuiyujie/.local/bin:/home/cuiyujie/anaconda3/bin:/home/cuiyujie/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/arm_4.4.3/bin
I tried the conda command again and checked the python version

I am using the linux version. I am sure I downloaded the Linux version.Anaconda3-2020.07-Linux-x86_64.sh But I entered the package of the environment I created, which contained .ddl and exe files, which was so strange. I uninstalled and reinstalled it several times. But Anaconda is the linux version, and the created environment is the window version.
Did you alias python=/path/to/python2.7 ?
Or maybe you can try:
conda deactivate
conda activate rcnn

Anaconda Navigator is for Setting up an environment or installing/updating packages in a specific environment of your choice. If you are having a new environment set up say, previously u have an existing 3.5 and now you are setting up 3.7 then, you will have to install the spyder kernel. Dont worry, when you start the system will flag this and you just have to install that through Navigator.
[Spyder > Tools > Preferences][1]
[1]: https://i.stack.imgur.com/qoSDV.png
Here in Spyder, your editor you typically would have the default python interpretor, change it to the environment of your choice.
[Prefernce > Set new python exe from specific environment][2]
[2]: https://i.stack.imgur.com/XiQro.png
So when you click on the Use the following interpretor, and open the file , you need to browse to the anaconda environment, select the respective version.
[Select Python Version][3]
[3]: https://i.stack.imgur.com/u4vQm.png
Now apply and say ok.
You need to restart your spyder for this to take effect for the first time.
It's very simple using Anaconda Navigator. Just choose your right environment and select Python version from the list. Check the screenshots for more clarity.
I am creating a new conda environment, and it is not clear to me why there are several required package dependencies that have the same name, but differ by a hyphen/underscore character. Here is an example snippet below from the package plan output. Thanks very much for any type of clarification. The only information I could find was that the noarch versions are platform independent, but it is still unclear then why there would be multiple versions required (and why the naming differs).

I had the same problem on Mac Mojave, and in my case run conda update --force conda first worked for me.

This worked for me on Linux:
Uninstall the package via pip:
pip uninstall setuptools
Reinstall using the following command:
conda install -c anaconda setuptools
Consider also that system packages (python3-setuptools, python-setuptools in Ubuntu) might need to be removed.
conda update --force conda
this worked for me in win64 when I
conda install -c https://conda.anaconda.org/sdvillal openslide-python
Silly point to make here but I've been caught by this before: you may not be in the environment you think you are. Just before killing off any package run a quick check to see:
conda env list
Performing ops on the base environment can cause issues, so you may want to create or change environment.
I had the same problem, which was due to a bad installation of a package (OpenEXR in my case).
Try to verify your package with conda list yourPackage.
If you find which one it is, prefer installing it with pre-built packages here : https://www.lfd.uci.edu/~gohlke/pythonlibs/.
A stack-overflow thread that helped me : Python 2.7, PIP: "Failed building wheel for ..."
EDIT :
Two friends had the same error, one solved it by installing/executing with admin rights.
The other one succeeded by creating a new virtual environnement for python.
I ran into the same problem, on macos, after removing all R packages installed by anaconda. Unfortunately, the only solution I found is to reinstall anaconda. Alternatively, you could download miniconda shell script installer, run it with -U option and point the installer at your conda directory. This fixed the issue for me while maintaining settings such as channel priority. However, many of previously installed packages were not importable (Python couldn't find them) and i ended up re-installing all of them.
I had the same problem. Try to use the command prompt to install wheel file if you get an error something like this(as shown in picture) then you must install that wheel file:
Extra(how to install wheel file from command prompt):
download wheel file as per the system specifications: -search required file here https://www.lfd.uci.edu/~gohlke/pythonlibs/ -e.g.
bsddb3 -click bsddb3 and search required file
open command prompt on your system
change the location on the command prompt to: where you have downloaded wheel file e.g C:\Users\Name\Downloads
go to the location, where you have installed python>>go to script>> copy the path (e.g C:\Program Files (x86)\Python36-32\Scripts)
write the command, to install wheel file using pip install (e.g. C:\Program Files (x86)\Python36-32\Scripts\pip install
copy_name_of_the_wheel_file)
run the command
try conda env create --force -f python3.6-environment-windows.yml
I'm not sure exactly where to place it but I use the --force whenever I run into issues like this like conda update --force conda or conda install --force ...
use it as last solution since it force conda to perform the command and you might run into some issues later on
I had solved the problem
RemoveError: 'setuptools' is a dependency of conda and cannot be removed from
conda's operating environment.
As the following way:
pip uninstall setuptools
conda update conda
conda update setuptools
and then check tools
I haven't met any mistakes yet, but help me correct my way , if something wrong, please
For me, deactivating the current conda environment solves the problem, i.e. run conda deactivate before upgrading.
I had to do the following steps to get it to work for me
conda update --force conda
This will run and update conda then run the following command
conda update conda
At each stage update all packages. After that, everything should work fine.
I'd like to use PyTorch in a Python program. The instructions for installing it require conda. After installing Conda I ran:
>conda install -c pytorch pytorch (as instructed on the PyTorch [page][1])

What is your platform?
For your first installation method, the error message says that you don't have the permission. I encountered that error before on a Linux system. The reason was that Anaconda was installed by another user. I configured the path to point python to that installation so that I could run python without installing my own copy of Anaconda. However, it didn't permit me installing new packages and I got the same error message.
Solution: I installed my own copy of Anaconda and everything worked.
just run:
pip install torch torchvision
An alternative way to install PyTorch is the following steps:
conda create -n pytorch_env python=3
source activate pytorch_env
conda install pytorch-cpu torchvision -c pytorch
Go to python shell and import using the command
import torch
Open the terminal in administrative mode and if you are in linux try
sudo pip install "your package name"
Installing packages to start running some code is perhaps the hardest part of my job.
