I'm been having some weird issue:
(quant) C:\Users\Randy666>conda deactivate
C:\Users\Randy666>
Some while ago I created an environment named "quant". Now, when I launch anaconda, it automatically opens with this environment active, and even if I deactivate this environment, when I re-open anaconda prompt, it still opens with 'quant' being active. How should I fix this problem?
The Anaconda prompt on windows is jsut a shortcut to the cmd. Yours was probably changed to activate the quant env automatically. Check the Target of the shortcut by simply Right-click->Properties on the Anaconda command prompt shortcut. My anaconda prompt has the target:
%windir%\System32\cmd.exe "/K" <path to anaconda or miniconda>\Scripts\activate.bat <path to anaconda or miniconda, i.e. the base env>
If you change the second path to any other env, then your anaconda prompt will automatically activate said env. To activate base instead, simply restore the path back to the base env.

Anaconda was installed by Systems Team on my work computer.
For reasons beyond this topic, they installed in Program Files, which I think is non-optimal.
So I ask permission to remove the installation and reinstall it via standard procedures.
When I open Anaconda PowerShell prompt it is still pointing to the Program Files installation which I have removed.
I have also checked the Path environmental variable, and there is nothing looking like Anaconda is still there.
How can I get Anaconda PowerShell prompt to work again?
It should be noted that conda command does work in regular command prompt.
Thanks.
Initialize conda for use with Powershell via
conda init powershell
This command should be run in Anaconda Prompt.
Before following #Peter's solution, I was able to track the problem via a more rustic procedure.
Right click on Start Menu's Anaconda PowerShell Prompt, and select Open File Location.
Right click on the icon's Properties, select Shortcut tab > Target field.
Copy the command to a text editor, and noticed it was still using an old location.
Changing the command to point to the right location did fix the problem.
... but that is only the command from the Start Menu, the rest is done by what was suggested before.
Thanks for the help.
I have recently reset my laptop and installed Anaconda in it, and I tried to open JupyterLab but it gives me error
Error executing Jupyter command 'lab': [WinError 5] Access is denied
but it works fine when I try to open JUPYTER NOTEBOOK or try to open JUPYTER LAB with Anaconda as administrator.
I reinstalled Anaconda, and still it gives me the same error. Also it gives me the same error when I try to open JUPYTER LAB from Anaconda Navigator. Before resting my laptop it works fine for me, but now it's not. I tried to search my query on the web before asking here, but I did not get my answer.
I want to run JUPYTER LAB with normal Anaconda prompt
Additional details
My Anaconda is installed in C:\ProgramData (by default).
I didn't check the box “add to path” while installing Anaconda.
You can just run it with Python:
python -m jupyterlab
This should work from an Anaconda Prompt or even the command prompt (if it uses the Python in Anaconda). It does not require admin rights.
Workaround:
open anaconda navigator
click on the jupyter lab settings option and then remove it
Now open your anaconda prompt and type the following command: conda install -c conda-forge jupyterlab
now try to open it.
Proper solution:
If you have installed Anaconda for all users then you will face this issue (thanks to Alok Rajasukumaran, who pointed out this). The best way to solve this problem would be to reinstall this for only the current user.
But if you have a requirement to install for all users, then you can follow these steps:
run the terminal as an administrator
type jupyter lab
Optional (Automating launching jupyter lab with shortcut)
If you want to automate these steps, then you can create a batch file and assign a keyboard shortcut to it. Steps are as follows:
open notepad and write "jupyter lab" and save it as a .bat file
right-click on that file and click on create shortcut.
now open the properties of created shortcut file and in the "shortcut-key" section type any combination of keys you want to set
shortcut.
click on "Advanced" and select "Run as administrator"
Now you can initiate jupyter lab directly by typing your shortcut key and giving "yes" permission to the prompt.
Try to execute as an admin. Problem solved.
This solution is unsafe. When you execute a program with Admin this program has full permissions over the system.
The good solution is to create a new environment with your current system user (not root/admin). Activate this new environment and it would works
Usually, you don't have error in opening jupyter notebook command.
I usually type the jupyter notebook in the path bar in the explorer to open the notebook from that path directly — but as we are having an error in jupyter lab, I was only able to open jupyter notebook from there.
The solution for that is:
Just type jupyter notebook as usual in the command prompt or the path bar in explorer.
As soon as the browser opens automatically, change the URL from:
http://localhost:8888/tree to → http://localhost:8888/lab
Yes, just a one word change. tree → lab and...
Whoo! The jupyter lab is open right there you want it to be!
This is a problem that I see happening for Anaconda 3 installs for all users on Windows. Default (for single user) install seems fine. The permissions are somehow messed up during install. The solution I found is: explorer > right click anaconda3 folder > properties > security > advanced > change permissions > check "replace all child permission entries..." > OK.
This will take a while. After that uninstalling and reinstalling Jupyter Lab worked well.
The problem I had is that it installed the application in users/<your username>/anaconda3/.
To solve this I simply manually moved the folder with its contents to c:/program files/.
Avoid running as Admin due to security concerns. The fastest way is to create a virtual environment and install it there. This is what I did and it did not require any reinstallation of Anaconda or running it as Admin.
in anaconda prompt:
conda create -n myenv python=3.9
conda activate myenv
conda install -c conda-forge jupyterlab
jupyter lab
the last line will launch the jupyter lab.
I want to emphasize what was written only as a comment, because it is easier to find it as an answer than to browse all comments:
If you are using Windows and installed it for all users, you will get this error.
The easiest way is to reinstall Anaconda only for you.
Note: You may uninstall your previous (unsuccessful) installation (for all users) before reinstalling it for only one user (you). But it is possible to do it later, too.
What I did is to create a new environment in Anaconda Navigator. I had the default environment which was root, so I could launch applications only as root.
In the Anaconda Navigator Home screen click on Environments -> Create. Here is the guide to create a new environment https://docs.anaconda.com/anaconda/navigator/tutorials/manage-environments/
Very inexperienced user here so forgive my ignorance.
Having a problem after launching Anaconda Prompt. I just get a flashing cursor. The top of the window reads 'Anaconda Prompt - C:\ProgramData\Anaconda3\Scripts\Activate.bat C:\ProgramData\Anaconda3'
I have tried reinstalling but it doesn't solve this issue - any ideas?
Thanks.
I have the same issue whenever i open the anaconda prompt it closes automatically so i've had a solution.
-Open the Start Search, type in “env”, and choose “Edit the system environment variables”
-Click the “Environment Variables…” button.
-add these paths under the path variables:
C:..\Anaconda3 [Anaconda path]
C:..\Anaconda3\Scripts
press "OK"
now in the Start search type cmd and write your conda commandes. cmd now is able to recognize your conda commands.I am using windows 10 .
I hoe this solution suits you well.
I just installed Anaconda for Python 2.7 on my laptop running 64 bit windows 8.
Once I finish installing Anaconda I go to open the Anaconda prompt and then I run conda update --all. This runs seemingly fine. When it's done running I close the prompt by hitting the close button in the upper right corner.
The issue comes in when I then go to open a new Anaconda prompt. I go to my start menu and open a new prompt. However, instead of the prompt that opened immediately after installing Anaconda I get a command window with these three lines:
>was unexpected at this time.
PATH > #IF NOT ""=="" #chcp > NUL
PATH >
An error seems to happen when I try to open my Anaconda prompt and then my path gets changed back to my default non-Anaconda command prompt path.
Could someone provide any help with this issue?
Thanks!
Facing the same issue. I have a habit of opening Jupyter notebook through anaconda prompt which I cannot do now. Fortunately, the jupyter notebook is opening through Anaconda navigator. Not sure what will I do to use "conda" commands until this issue is solved
Same issue, except that my installation is already 2 months old, suddenly noticing this today.
Olivier.
Open the anaconda prompt and change the anaconda prompt directory to Anaconda/Scripts and then you can use the conda commands.
I have Anaconda installed on my computer but when I type a command in cmd I only get 'conda' is not recognized as an internal or external command,
operable program or batch file. What could be the problem? It's the same with pip.
I can see that it is installed in my settings.
So Anaconda should have added jupyter to your PATH automatically during the install if you selected that option as shown in the installation video, if you did not select it, you need to do this manually, here are the steps to do so:
1)go to mu cpmuter properties and click on ADVANCE SYSTEM SETTINGS
2)Select the Advanced tab.
3)Click the Environment Variables button.
4)Under System Variables, select Path, then click Edit.
You'll see a list of folders, as this example for my system shows something like:
C:\Program Files\Windows Resource Kits\Tools\;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;
You will notice that each of these file paths are separated by a semicolon ;
You can add additional folders that you want to include in searches. In this case, you need to add Anaconda to your path, it will be something like: C:\Users\myusername\Anaconda2
Add that to the list, make sure your spacing is correct
You'll need to restart the processes (e.g., command prompt) that use the system path to see the added folders.
-----------------------------------------------------------------------------## YOU CAN ALSO AVOID THIS MANUAL PROCESS ##
ANOTHER METHOD is reinstall this and while doing this make sure of thing that is shown in the scr shot below
while installing the anaconda the dialogue box appears giving two options
add anaconda to my path enviorment variable
register anaconda as my default python version
select both of this options though system will not recommend this but you have to mark
thankyou!!
all the best!!
Open your Anaconda Prompt instead of just your command prompt. Then type "conda list," you should get the correct output. I suspect that you did not add Anaconda to your PATH during installation and that's why your regular command prompt won't recognize the conda commands.
Find where you anaconda is installed. Usually, it is under %USERPROFILE%\AppData.... You can set path using SETX PATH on CMD. e.g. I have installed anaconda3. It was installed in its default path.
e.g.
SETX PATH “%USERPROFILE%\AppData\Local\Continuum\Anaconda3; %USERPROFILE%\AppData\Local\Continuum\Anaconda3\Scripts”
If you do not know where anaconda was installed, you can open "Anaconda prompt" app. You can see the environment path to your anaconda [You can find "Anaconda prompt" using Search Windows.
