Is it possible to use a different IDE as a front end while using the Canopy EPD engine in the back end? In particular, I'd like to use mayavi.mlab scripting from Spyder's ipython interpreter. I'm working on a macbook pro running OSX 10.8. Is there a way to set this up?
I have tried to set up mayavi and spyder using macports, but that does not seem to work. The only working version of mayavi that I have managed to set up runs from the commercial Canopy platform. So if I can't get the macports mayavi to work with the macports spyder, I am hoping to get the Canopy mayavi working with spyder.
Thanks.

(Spyder dev here): This is what you need to do:
Run this command in a console
enpkg ipython update
Go to
Spyder > Preferences > Console > Advanced Settings > Python Executable
Select the option
Use the following interpreter
Note: This option is not available right now but it will be in 2.2.3. If it's not, then just the text field present there.
Put there the full path to Canopy's Python version, which you can get with these commands inside Canopy:
In [10]: import sys
In [11]: sys.executable
Out[11]: '/home/carlos/Enthought/Canopy_64bit/User/bin/python'
Maybe I'm missing what you want to do (I don't even know what mayavi is), but here's something you can try.
I'm using Spyder (version 2.2.1 ) with the Canopy EPD distribution (version 1.0.3)
Try doing this:
1) At the command line, update ipython with the enpkg command ( "enpkg ipython update" should work)
In my case, this reverted the ipython to ipython-0.13.1-2
2) Then in Spyder, go to preferences -> Console -> Advanced Settings and in the python executable put something like /Users//Library/Enthought/Canopy_64bit/User/bin/python
Restart Spyder and now you should be able to use the EPD distribution with all the modules you have installed.

I've been trying to use the packages pandas, numpy, matplotlib, seaborn in my "Visual Studio Code", but the program keeps showing me the following message:
"import pandas could not be resolved from source Pylance(reportMissingModuleSource)"
Previously to Visual Studio Code I installed "Anaconda" to use Jupyter, and now it says that i have the existing packages (pandas, numpy...) but keeps appearing this message that doesn't allow me to use pandas in my Visual Studio.
Anyone could help me to solve this issue?
I tried installing again all the packages to check if they didn't exist but apparently are installed all of them but in another route. I can't find how is the way to put them so the Visual Studio Code recognizes them and I can use them.
I also received similar an error on my IDE VSCode and currently using mac m1 .First we need to make sure that the python3 interpreter version from terminal version is the same with our python version selection in VSCode.
open terminal.
type 'python3'
then you will see your python version.(my python3 version is 3.9.12)
python3 version
open your IDE VSCode
open any/current folder that related to python project on IDE VSCode
Check your python version at the bottom right on IDE VSCode (in my case the python version is 3.10.64)
change or switch VSCode python version from 3.10.64 to 3.9.12 (same with your python version on your pc)
done
I also had this problem and it was because of version mismatches.
I had installed Python AND Anaconda. If anyone else has done this and gets this error, you need to uninstall both. Then install Anaconda only; Python (the compatible version) is installed as part of that process.
See https://docs.anaconda.com/anaconda/install/windows/
Also, you can click on the interpreter version at the bottom left corner of the screen (Vs.code 2022) it should show a dropdown menu with a list of the available and selected python interpreter. Click on add interpreter path and paste the path to the python interpreter with all the required modules installed and click enter. This should resolve the problem.
I re-entered the path to Python interpreter and warning disappeared. Hope that helps you.
Another way I solved this issue having followed every other installation process to the letter was deactivating Pylance. Works a (py)charm now.
I encountered this problem in VSCode under remote to WSL2 of Windows 10. The Python version is correct as interpreter (3.9.13) and the terminal in VSCode is also under the same envs (ie. VSCode ran "conda activate xx" and (xx) is shown in prompt)
Originally, I tried to install the pandas by the following command.
sudo apt-get install python3-pandas
Pandas was installed successfully as stated in the terminal but the problem is still there.
When I try to install pandas by the following command, the problem solved.
pip install pandas
Until today, matplotlib was working with vscode. TOday I updated vscode to the latest version and found that plots don't work. They work from the same virtual environment using the python interpreter but not from vscode. I rolled back to earlier versions of both matplotlib and vscode, but it still doesn't work. Here is my code to plot:
import matplotlib
import matplotlib.pyplot as plt
plt.plot([1,2],[3,4])
plt.show()
The version of vscode is 1.53.2 and the version of matplotlib is 3.3.4
If I call plt.savefig, it saves the figure. It just doesn't display interactively.
I have tried this with multiple virtual envioronments and multiple vscode workspaces, all of which worked before today.
VSCode doesn't see my DISPLAY environment variable on my Linux system, so it is running headless. I can make plots work by giving the command "export DISPLAY=:0" in the vscode terminal window. I would like to have this happen automatically but I don't know how to make that happen.
The way I discovered this was by inserting "matplotlib.use("TKAgg")" in my python script. This elicited a message saying that I was running headless.
The way I found the correct value for DISPLAY was to examine that variable in a terminal window outside of vscode.
When I went to report this on the vscode Github page, I found the suggestion to disable all extensions. When I do that, I don't have to set DISPLAY. I then went and reenabled all extensions, and plotting still works, so it seems the fix was to disable and reenable all extensions.
Mine is Anaconda 5.3.0
When I run .py in PyCharm 2018.2.4, why it shows that:
ImportError:
DLL load failed: The specified module could not be found.
ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
Original error was: DLL load failed: The specified module could not be found.
It seems that PyCharm 2018.2.4 cannot import numpy??
Does anyone see this problem too? How to fix it? Thank you very much.
You can set the Python interpreter path on PyCharm to the Anaconda one (something like ~/anaconda3/bin/python).
Todo do so, open the Settings dialog >> Project: [ProjName] in the left panel >> Project Interpreter. Now you can add to the list paths to local Python interpreters, or virtual environments in the project folder or in a folder specified in the WORKON_HOME.
More instructions here and here.
I believe I have useful information if not the solution.
I too received the error using python to import numpy from the windows command prompt. Then I realized I could succeed if I used the Anaconda prompt. Curious about the difference, I exited python and examined the PATH environment variable. As I had hoped, it contained Anaconda references that did not exist in the Windows PATH. At the command prompt I typed: path > p.txt and hit enter to create a file since the string was so long. When I opened the file in notepad I copied the Anaconda references to the clipboard (C:\Users\laptop\Anaconda3;C:\Users\laptop\Anaconda3\Library\mingw-w64\bin;C:\Users\laptop\Anaconda3\Library\usr\bin;C:\Users\laptop\Anaconda3\Library\bin;C:\Users\laptop\Anaconda3\Scripts;C:\Users\laptop\Anaconda3\bin;) then used the Advanced Settings under the System Control Panel to Edit the Environment Variable and paste it on the beginning of PATH. The problem seems to have gone away, both in the Windows shell and in Pycharm.
First, try to delete .git file from project folder and re-enable vcs. Then uninstall numpy by:
pip3 uninstall numpy
After that, go to pycharm and open File > settings > Project Intepreter get the python location url ex: usr/bin/python3. Copy that path and open terminal and type:
usr/bin/python3 install numpy. Wait for pycharm indexing and try to run project again
I don't think it's an issue with PyCharm.
I got Anaconda 5.3 today and use PyCharm Pro 2018.2.4. Unfortunately, I got the same error as you do. However, if you go to powershell (if you are on Windows like me), type in python and import numpy you still got the same error.
Not sure why yet but uninstall & reinstall didn't help (and tbh I don't get why this might help in any sense though).
So my current solution is:
Roll back to Anaconda 5.2 with Python 3.6 and everything gets back to working.
I have the same thing, pychrm 2018.2 & Anaconda3 (64-bit) 5.3 on win10
I think the issue is about Anaconda, I have uninstalled the Anaconda 5.3 and installed Anaconda 5.2, then everything is ok
I have installed NumPy using pip install and it's working fine while using it in the python interpreter on the command line. But whenever I try
import numpy in PyCharm it throws an error module not found.
I already set the right path in the project interpretor and the import numpy command is working fine with other IDEs such as Syder or Jupyter notebook but it doesn't work in PyCharm.
I found a YouTube video that worked for me in importing a package into PyCharm. First, click on the File menu, then click on Settings, then click on Project Interpreter. Look for a + sign to the right and click on that. That allows you to add a package. Then search for your package of choice (I wanted numpy) in the Search bar at the top. Click on the name, and then at the bottom click on Install Package. After a few minutes, it will say, package successfully installed, and sure enough it was. I was able to import numpy the usual way in PyCharm.
Did you install official Python or Anaconda/Miniconda?
I assume PyCharm created either a virtualenv or a conda env, or an isolated Python environment that does not have NumPy installed.
You should either use your global environment instead of virtualenv:
Settings, Project: project-name / Project Interpreter, https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html
Or install NumPy in your virtualenv or conda env.
This is more complicated. If you open Terminal in PyCharm and it says (project-name) in your prompt, try pip install numpy.
I have an existing PyQt5/Python3.4 application that works great, and would now like to add "real-time" data graphing to it. Since matplotlib installation specifically looks for Python 3.2, and NumPhy / ipython each have there own Python version requirements, I thought I'd use a python distribution to avoid confusion.
But out of all the distros (pythonxy, winpython, canopy epd) Anaconda is the only one that supports Python 3.4, however it only has PyQt 4.10.4. Is there a way I can install Anaconda, and use matplotlib from within my existing PyQt5 gui app?
Would I be better off just using another charting package (pyqtgraph, pyqwt, guiqwt, chaco, etc) that might work out of the box with PyQt5/Python3.4?
I was able to install it from dsdale24's and asmeurer's channels but then, when trying to run a qt script with a QApplication object, I got an error message regarding to cocoa library not being found.
Then, following asmeurer's comment, I could install PyQt5 on anaconda with python 3.4 using the mmcauliffe package:
conda install -c https://conda.anaconda.org/mmcauliffe pyqt5
Now it works great!
We are working on adding pyqt5, but for now, you can install it from https://binstar.org/dsdale24/pyqt5.
conda config --add channels dsdale24
conda install pyqt5
create an env like this:
conda create –name my_env python=3.5 pyqt=5
works great.
I use Anaconda and with Python v2.7.X and qt5 doesn't work. The work-around I found was
Tools -> Preferences -> Python console -> External modules -> Library: PySlide
