I installed Anaconda3 4.4.0 (32 bit) on my Windows 7 Professional machine and imported NumPy and Pandas on Jupyter notebook so I assume Python was installed correctly. But when I type conda list and conda --version in command prompt, it says conda is not recognized as internal or external command.
I have set environment variable for Anaconda3; Variable Name: Path, Variable Value: C:\Users\dipanwita.neogy\Anaconda3
How do I make it work?
I was faced with the same issue in windows 10, Updating the environment variable following steps, it's working fine.
I know It is a lengthy answer for the simple environment setups, I thought it's may be useful for the new window 10 users.
1) Open Anaconda Prompt:
2) Check Conda Installed Location.
where conda
3) Open Advanced System Settings
4) Click on Environment Variables
5) Edit Path
6) Add New Path
C:\Users\RajaRama\Anaconda3\Scripts
C:\Users\RajaRama\Anaconda3
C:\Users\RajaRama\Anaconda3\Library\bin
7) Open Command Prompt and Check Versions
8) After 7th step type
conda install anaconda-navigator in cmd then press y
Although you were offered a good solution by others I think it is helpful to point out what is really happening. As per the Anaconda 4.4 changelog, https://docs.anaconda.com/anaconda/reference/release-notes/#what-s-new-in-anaconda-4-4:
On Windows, the PATH environment variable is no longer changed by default, as this can cause trouble with other software. The recommended approach is to instead use Anaconda Navigator or the Anaconda Command Prompt (located in the Start Menu under “Anaconda”) when you wish to use Anaconda software.
(Note: recent Win 10 does not assume you have privileges to install or update. If the command fails, right-click on the Anaconda Command Prompt, choose "More", chose "Run as administrator")
This is a change from previous installations. It is suggested to use Navigator or the Anaconda Prompt although you can always add it to your PATH as well. During the install the box to add Anaconda to the PATH is now unchecked but you can select it.
I found the solution.
Variable value should be C:\Users\dipanwita.neogy\Anaconda3\Scripts
When you install anaconda on windows now, it doesn't automatically add Python or Conda to your path.
While during the installation process you can check this box, you can also add python and/or python to your path manually (as you can see below the image)
If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt
where python
where conda
Next, you can add Python and Conda to your path by using the setx command in your command prompt (replace C:\Users\mgalarnyk\Anaconda2 with the results you got when running where python and where conda).
SETX PATH "%PATH%;C:\Users\mgalarnyk\Anaconda2\Scripts;C:\Users\mgalarnyk\Anaconda2"
Next close that command prompt and open a new one. Congrats you can now use conda and python
Source: https://medium.com/#GalarnykMichael/install-python-on-windows-anaconda-c63c7c3d1444
Just to be clear, you need to go to the controlpanel\System\Advanced system settings\Environment Variables\Path,
then hit edit and add:
C:Users\user.user\Anaconda3\Scripts
to the end and restart the cmd line
In addition to adding C:\Users\yourusername\Anaconda3 and C:\Users\yourusername\Anaconda3\Scripts, as recommended by Raja (above), also add C:\Users\yourusername\Anaconda3\Library\bin to your path variable. This will prevent an SSL error that is bound to happen if you're performing this on a fresh install of Anaconda.
If you have a newer version of the Anaconda Navigator, open the Anaconda Prompt program that came in the install. Type all the usual conda update/conda install commands there.
I think the answers above explain this, but I could have used a very simple instruction like this. Perhaps it will help others.
Go To anaconda prompt(type "anaconda" in search box in your laptop). type following commands
where conda
add that location to your environment path variables. Close the cmd and open it again
This problem arose for me when I installed Anaconda multiple times. I was careful to do an uninstall but there are some things that the uninstall process doesn't undo.
In my case, I needed to remove a file Microsoft.PowerShell_profile.ps1 from ~\Documents\WindowsPowerShell\. I identified that this file was the culprit by opening it in a text editor. I saw that it referenced the old installation location C:\Anaconda3\.
For conda --version greater than 4.6, from the base of your Anaconda promt, run
conda update conda
conda init
This will update your conda root environment and setup the stuff you need to run it on both cwd and powershell.
After this, you can start any terminal and it will be conda ready.
If you don't want to add Anaconda to env. path and you are using Windows try this:
Open cmd;
Type path to your folder instalation. It's something like:
C:\Users\your_home folder\Anaconda3\Scripts
Test Anaconda, for exemple type conda --version.
Update Anaconda: conda update conda or conda update --all or conda update anaconda.
Update Spyder:
conda update qt pyqt
conda update spyder
I have Windows 10 64 bit, this worked for me,
This solution can work for both (Anaconda/MiniConda) distributions.
First of all try to uninstall anaconda/miniconda which is causing problem.
After that delete '.anaconda' and '.conda' folders from 'C:\Users\'
If you have any antivirus software installed then try to exclude all the folders,subfolders inside 'C:\ProgramData\Anaconda3\' from
Behaviour detection.
Virus detection.
DNA scan.
Suspicious files scan.
Any other virus protection mode.
*(Note: 'C:\ProgramData\Anaconda3' this folder is default installation folder, you can change it just replace your excluded path at installation destination prompt while installing Anaconda)*
Now install Anaconda with admin privileges.
Set the installation path as 'C:\ProgramData\Anaconda3' or you can specify your custom path just remember it should not contain any white space and it should be excluded from virus detection.
At Advanced Installation Options you can check "Add Anaconda to my PATH environment variable(optional)" and "Register Anaconda as my default Python 3.6"
Install it with further default settings. Click on finish after done.
Restart your computer.
Now open Command prompt or Anaconda prompt and check installation using following command
conda list
If you get any package list then the anaconda/miniconda is successfully installed.
I have just launched anaconda-navigator and run the conda commands from there.
For those who didn't check "Add Anaconda to my PATH environment variable". In Windows 10 it looks like that:
5 paths:
C:\Users\shtosh\anaconda3
C:\Users\shtosh\anaconda3\Library\mingw-w64\bin
C:\Users\shtosh\anaconda3\Library\usr\bin
C:\Users\shtosh\anaconda3\Library\bin
C:\Users\shtosh\anaconda3\Scripts
if you use chocolatey, conda is in C:\tools\Anaconda3\Scripts
I had this problem in windows. Most of the answers are not as recommended by anaconda, you should not add the path to the environment variables as it can break other things. Instead you should use anaconda prompt as mentioned in the top answer.
However, this may also break. In this case right click on the shortcut, go to shortcut tab, and the target value should read something like:
%windir%\System32\cmd.exe "/K" C:\Users\myUser\Anaconda3\Scripts\activate.bat C:\Users\myUser\Anaconda3
I installed latest anaconda in C:\Users\Username\Anaconda3.
But the navigator and prompt are missing after installation.
I tried to re-install(as administrator) and reboot the window 10 but it didn't work.
I also tried to delete registry of python which was under HKEY_LOCAL_MACHINE\SOFTWARE as written in following page.
https://docs.anaconda.com/anaconda/user-guide/troubleshooting/#cannot-see-anaconda-menu-shortcuts-after-installation-on-windows
Running 'conda' in command prompt only shows it's not recognized as an internal or external command.
It seems like Anaconda is not installed but just creating bunch of python package in the folder.
Can someone share the idea?
My environment is Window 10 64bit
Thank you very much.
Cleaned user variables in Control Panel -> System -> Advanced System settings -> Environment Variable. Re-installed latest Anaconda in https://repo.anaconda.com/archive/
Now Navigator and Prompt are showing correctly.
I use Anaconda frequently to manage python packages on a Windows machine. But I'm having trouble understanding how it works on a Ubuntu, probably because I'm new to Linux in general.
I downloaded the Anaconda Linux installer (python 3) and run bash ~/Downloads/Anaconda3-5.2.0-Linux-x86_64.sh to install. After installation, I was able to type anaconda-navigator in terminal to start the GUI, where I created a new python 3.6 environment called tensorflow_env. But I couldn't activate it in the terminal. I followed the error message and typed
echo ". /home/chris/anaconda3/etc/profile.d/conda.sh" >> ~/.bashrc
in the terminal, which solved the problem.
To validate, here is how it looks like now in my terminal:
Being a frequent Anaconda user in Windows, what I don't understand is when I clicked open terminal from the green triangle in the GUI (see screenshot below),
The opened conda terminal still says bash: activate: No such file or directory. And if I test Python, as you can see it's not even python 3.
What's going on with the navigator? It still can't activate environments.
I have installed Anaconda for python2 as per official documentation. In the end I received message about successful installation. To check I typed ipython and its terminal is displayed successfully but on doing conda --version nothing comes. I have checked following:
which python : It gives /home/username/anaconda2/bin/python
sha of downloaded package: It is correct
Other Anaconda installed package (ipython): It's terminal comes up
which conda: /home/username/anaconda2/bin/conda
Closed terminal and again open it(mentioned in docs). Checked after shutdown also !
On doing anaconda-navigator following message comes:
Please activate the conda root enviroment properly before running the
anaconda-navigator command.
To activate the environment please open a terminal and run:
source /home/username/anaconda2/bin/activate root
For more information please see the documentation at:
https://docs.anaconda.com/anaconda/navigator/
On doing as suggested above, nothing happens and the problem persists. Since I am new to this, might be missing something tivial, please suggest?
I was facing the exact same issue on Ubuntu 17.04 x64. In my case it was the usage of a different shell than the default (bash).
I installed the program using my ZSH shell.
During installation it asks:
Do you wish the installer to prepend the Anaconda<2 or 3> install
location to PATH in your /home/user/.bashrc ?
That made me try to run the Anaconda Navigator using bash shell (just use the bash command to switch). And yes it worked.
If you look into the .bashrc you will notice that the installer appended something like:
export PATH="/home/user/anaconda2/bin:$PATH"
If you export the path to ZSH (or any other shell you use) then it will work with your shell as well. In the case of ZSH just copy the export PATH line to the end of .zshrc
I installed anaconda into my computer using python. After I install the software, I found there is one program called anaconda prompt.
What is the difference between anaconda prompt and command prompt? If I want to update the package, which one I should use or either one. Like (conda update conda)
Thank you
Anaconda command prompt is just like command prompt, but it makes sure that you are able to use anaconda and conda commands from the prompt, without having to change directories or your path.
When you start Anaconda command prompt, you'll notice that it adds/("prepends") a bunch of locations to your PATH. These locations contain commands and scripts that you can run. So as long as you're in the Anaconda command prompt, you know you can use these commands.
During the installation of Anaconda there is a choice to add these to the PATH by default, and if checked you can also use these commands on the regular command prompt. But the anaconda prompt will always work.
As far as updating conda, if it doesn't work in command prompt, you can do
conda update conda
in Anaconda command prompt.
When you use anaconda command prompt it opened at conda directory (path where all the conda commands run)
like when I was installing pip3 install prettytable on command prompt it successfully installed but not replicate in jupyter notebook.
But when install it using anaconda prompt it replicates intantly
Here is the difference:
PATH-TO behind is the path to Anaconda3
Afer adding the following env to Windows command prompt, it will be the same as Anaconda prompt:
set CONDA_DEFAULT_ENV=base
set CONDA_PREFIX=PATH-TO\Anaconda3
set CONDA_EXE=%CONDA_PREFIX%\Scripts\conda.exe
set CONDA_PROMPT_MODIFIER=(base)
set CONDA_PYTHON_EXE=%CONDA_PREFIX%\python.exe
set CONDA_SHLVL=1
set Path=%CONDA_PREFIX%;%CONDA_PREFIX%\Library\mingw-w64\bin;%CONDA_PREFIX%\Library\usr\bin;%CONDA_PREFIX%\Library\bin;%CONDA_PREFIX%\Scripts;%CONDA_PREFIX%\bin;%CONDA_PREFIX%\condabin;%Path%
I see great answers but maybe it is a little technical for beginners. Anaconda is a (software) distributor, in this case for Python, and its anaconda command prompt is similar to windows command prompt with one important difference: having PATH. PATH, as it can be assumed from its name, is like an address in computer where python packages are installed and their computations will be run.
Having PATH makes a big difference between using python via anaconda prompt or normal command prompt which is considered useful for many research teams and business computers: it will allow you to install, update and uninstall packages inside a separate environment (after creating one!) so that other members of the team wouldn't be disturbed.
When I was working with my own laptop, I never had any problem with running python on jupyter using windows command prompt. But for working with a research team PC, my supervisor made me to create a virtual environment named after me in anaconda prompt just not to disturb any other member. Actually, that was a pain in my neck because I have to activate "my environment" every time before starting python on jupyter. I never understand why someone should not appreciate if I install any more extra packages or updates for them? Not to mention, if in a million years an error pops up due to a package I installed, they can simply uninstall or downgrade it.
So as a normal researcher with medium computations in python, I never liked working with anaconda prompt and windows command prompt was everything I needed, especially on my OWN laptop.
I hope you liked my idea.
