Python beginner here. I would like to use Spyder as my Python IDE. Alas the standalone version does not include pip and I want to work with "Vanilla Python" rather than Anaconda. So I installed Spyder via
pip install spyder, which works fine. However, when running spyder3 in the command window, nothing happens. I get no error, but Spyder does not launch either. While the Spyder website says custom installation may be tricky, it does not provide a guide on how to get it done. Does someone know how? OS is Windows 10.
you need to follow this commands:
python -m venv spyder-env
spyder-env/Scripts/activate.bat
pip install spyder
more info
Update: Tried again with Python 3.10.4. "spyder" now exists in the Scripts folder and does launch when typing spyder in cmd. Works for me now.
I want to install the module arcpy in spyder anaconda. I run the following command in Anaconda Prompt: conda install arcpy -c esri, which follows https://pro.arcgis.com/en/pro-app/latest/arcpy/get-started/installing-arcpy.htm. But it fails. The message shows as below:
The python version is 3.7.10. I'm also using ArcGIS Desktop 10.7.1.
Does anyone know how to figure this out? Thanks
You need to run Spyder within the ArcGIS Pro conda environment, that is c:\Progra~1\ArcGIS\Pro\bin\Python\envs\arcgispro-py3
See: https://pro.arcgis.com/en/pro-app/latest/arcpy/get-started/using-conda-with-arcgis-pro.htm
I am trying to make a jupyter notebook in visual studio code but I keep getting this:
''Unable to start session for kernel Python 3.8.3 64-bit ('Lenovo':
virtualenv). Select another kernel to launch with.''
I have anaconda installed and the jupyter notebook works fine in the anaconda navigator. I also tried to use python 3.8.3 base:'conda' but it didnt work. I'm using windows 10
This issue also occurs on my computer. The solution is to restore the version number of a dependency package "traitlets" of ipython kernel to 4.3.3.
You could try to use "pip list" to view the version of the module "traitlets" in the current virtual environment. If it shows version 5.0, it is recommended that you use version 4.3.3.
You could reinstall "traitlets 4.3.3" with the following command:
python -m pip install 'traitlets==4.3.3' --force-reinstall
If this command is not available, you could use 'pip' to uninstall traitlets5.0 (pip uninstall traitlets) and then use 'pip' to install traitlets4.3.3.(pip install traitlets==4.3.3)
Reference: Unable to start session for kernel Python.
I had the exact same problem. Fix it by uninstalling the Python extension that is linked to that error message.
If you are using conda to manage your Python environments, activate your target environment at a command prompt, then enter the following:
$ conda install traitlets=4.3.3
This solved the problem for me.
I've been using Anaconda for Python and I am having a problem finding a comprehensive guide on how to install Wxpython.
From what I've pieced together, I downloaded Wxpython from condaforge then entered 'conda install -c anaconda wxpython' into the Anaconda prompt.
and then when i went to Spyder and typed in 'import wx' nothing happens. How do I get Wxpython up and running?
In the first step I would check if you are loading spyder in the root enviorment:
if you have naother enviorment, you need to run:
activate YourEnviorment
before running
conda install -c anaconda wxpython
after this if you run a package in spyder your console will ouput this:
so in general, if no error occurs, you succesfully loaded your library!
I downloaded spyder using the
pip install spyder
in my windows 10 32-bit operating system, but i dont see any desktop icons or exe files to start running the IDE. I downloaded spyder 3, any my python is 3.6.
I even tried creating a shortcut of spyder.exe from the Python3.6/Scripts folder, but it won't open.
The name of the spyder executable was changed to spyder3.exe in python version 3.
I install pyqt5 and spyder via pip and was able to launch spyder3. I first tried without installing pyqt5 and nothing happened. Once I installed pyqt5, then spyder 3 opened.
Try the following from a windows cmd.exe prompt:
C:\Users\..>pip install pyqt5
C:\Users\..>pip install spyder
C:\Users\..>spyder3
I had the same problem after setting up my environment on Windows 10. I have Python 3.6.2 x64 installed as my default Python distribution and is in my PATH so I can launch from cmd prompt.
I installed PyQt5 (pip install pyqt5) and Spyder (pip install spyder) which both installed w/out error and included all of the necessary dependencies.
To launch Spyder, I created a simple Python script (Spyder.py):
# Spyder Start Script
from spyder.app import start
start.main()
Then I created a Windows batch file (Spyder.bat):
#echo off
python c:\<path_to_Spyder_py>\Spyder.py
Lastly, I created a shortcut on my desktop which launches Spyder.bat and updated the icon to one I downloaded from the Spyder github project.
Works like a charm for me.
Try these commands in order
pip3 install spyder
spyder3
Try the command spyder3
If you check the scripts folder you'll find spyder3.exe
As stated in the documentation of Spyder, you need to install PyQt5 first.
Open a Command Prompt as Administrator, then run:
pip install pyqt5
pip install spyder
Then you can find the spyder3.exe in the Python3.6/Scripts folder. You can also make a shortcut to it. No need for Anaconda.
method 1:
spyder3
method 2:
python -c "from spyder.app import start; start.main()"
method 3:
python -m spyder.app.start
Open a command prompt. Enter the command spyder. Does anything appear? If an exception is preventing it from opening, you would be able to see the reason here. If the command is not found, update your environment variables to point to the Python3.6/Scripts folder, and run spyder again (in a new cmd prompt).
If you are using Anaconda execute the following commands and your life will be saved!
conda update qt pyqt
conda update spyder
In case if you want the desktop icon
In desktop, create a new shortcut, in Location paste this
%comspec% /k spyder3
then type the name Spyder,
Now you may have Desktop Icon for opening Spyder
After pip install spyder give this command
pip install --upgrade spyder
This command will update all Spyder dependencies.
Now in command prompt(cmd) navigate to the scripts folder in your python directory. In my system the path is C:\Users\win10\AppData\Local\Programs\Python\Python36-32\Scripts so i use the following command in command prompt.
cd C:\Users\win10\AppData\Local\Programs\Python\Python36-32\Scripts
once you are inside scripts directory type spyder3 and press enter and spyder ide starts.
C:\Users\win10\AppData\Local\Programs\Python\Python36-32\Scripts>spyder3
on windows,
pip install --upgrade spyder
in powershell, start python shell, by typing python
from spyder.app import start
start.main()
That't it.
Install Ananconda packages and within that launch spyder 3 for first time. Then by second time you just click on spyder under anaconda in all programs.
