I am originally a Fortran programmer, if anything. Last year I begun learning python and now I wanted to use fortranmagic to have a wrapper of f2py, but it is not working. Let me describe the steps I took and the resulting error messages, hoping for some help. I am working with Ubuntu 22.04
I begun by creating an environment conda create -n lf and activating the environment
I installed I few libraries I might need
conda install numpy scipy matplotlib jupyter nodejs
Following the instructions of the Fortran-magic developer GitHub I run pip install -U fortran-magic
Everything installs fine, but when I create a notebook and execute
%load_ext fortranmagic
I get the following error ModuleNotFoundError: No module named 'fortranmagic'
4. I finally try to install the extensions from jupyter, as it is also suggested in the developer GitHub
%install_ext https://raw.github.com/mgaitan/fortran_magic/master/fortranmagic.py
Yet only to receive the following error UsageError: Line magic function %install_ext not found.
I hope you can help
So basically I am using PyCharm with Anaconda env Python 3.6. I tried reinstalling everything, folder with my projects env contains the whole package for opencv, in Anaconda Navigator also and PyCharm recognises cv2 when I import (code) yet when i start my main.py it says that there is no cv2 module.
Anyone any ideas why the error occurs?
I suppose the first thing you should check is if your conda environment is configured to your project when you're using PyCharm. Have a look at this: https://docs.anaconda.com/anaconda/user-guide/tasks/pycharm/#:~:text=Configuring%20a%20conda%20environment%20in%20PyCharm,-In%20the%20Settings&text=Select%20Preferences.,dialog%20box%2C%20select%20Conda%20Environment.
Happy October everyone,
I've successfully downloaded modules before using either the pycharm installer or pip through the command screen, but for some reason when installing matplotlib pycharm cannot recognize it. I've uninstalled and reinstalled, I've installed through both methods, I've followed past similar questions asked on this site which make sure that you have the same interpreter and that it was installed in the right folder (pycharm error while importing, even though it works in the terminal).
So, here's the whole problem. Here's is the simple code, submitted into both pycharm and IDLE:
import matplotlib.pyplot as plt
plt.plot([1,2,3],[2,1,3])
plt.show()
When submitted into IDLE, my plot appears. When submitted into pycharm, the following error appears:
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:/PythonProject/matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
File "C:\PythonProject\matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
ImportError: No module named 'matplotlib.pyplot'; 'matplotlib' is not a package
I am currently running Python 3.4, PyCharm 2016.2.3, and my matplotlib folders are indeed in my site-packages folder inside my Python34 folder. Also for further verification:
PyCharm installation
Please help I've become frustrated since this is the only module I've run into trouble with. I've scoured StackOverflow and related websites to help, I've made sure I have all the requirements, etc.
I guess if you named your current writing python module as matplotlib.py.That cause the python load your current writing module instead of the actual matplotlib.py, which triggers an error.
I recommend you to use virtualenv. Is not strictly necessary but is good for dividing your project environments.
This is how I tested matplotlib on my Windows 10 installation, hope it helps.
Be sure that you have the python 3 installation folder listed in your Windows PATH environment variable, should be already listed if you checked "Add Python 3.5 to PATH":
You need also to set the Scripts folder in your PATH environment variable usually should be this path:
C:\Users\<your username>\AppData\Local\Programs\Python\Python35\Scripts
If you don't do that you have to prepend python -m to every command below like this: python -m <command>, so the command below would be python -m pip install virtualenv. I prefer the first solution.
To test matplotlib on Pycharm I've used virtualenv, here is how; first install virtualenv:
pip install virtualenv
Then you create your virtual environment in a folder of your choice, in my case I used python_3_env_00:
virtualenv python_3_env_00
After that you can activate you python 3 virtual environment:
python_3_env_00/Scripts/activate.bat
Now you should see in your command line the active virtual environment (python_3_venv_00), like this:
Now you can install matplotlib:
pip install matplotlib
Fire up PyCharm and add your virtual environment as you project interpreter, go to File->Settings search for Project Interpreter click on the gear icon and Add Local and set the path of your virtual environment, should look like something like this:
Test it:
import sys
print(sys.path)
run this code in where the import worked, and run it in the Pycharm project. Compare the lists. Find out which path that is not present in Pycharm sys.path.
Before importing pyplot, append the missing path to sys.path.
import sys
sys.path.append("the path")
import matplotlib.pyplot as plt
Does this work?
Please follow below steps if you are still getting an error:
If you are using PyCharm, it automatically create virtualenv.
Ensure Scripts path is set into PATH
C:\Users\<Username>\AppData\Local\Programs\Python\Python37-32
Then open PyCharm and go to File-> settings. Search for Project Interpreter. You will see window like this
sample image
Click on setting icon -> Existing Environment -> click on ... give below path
C:\Users\Krunal\AppData\Local\Programs\Python\Python37-32\python.exe
Click on Apply -> ok and you are good to go.
After installing matplotlib When I was trying to use matplotlib.pyplot it was giving error module not found.
I browsed some white papers and found out that we also need to install scipy library to use the matplotlib so I used the below in my command prompt
python -mpip install scipy
Restarted my kernel session.
It worked!!!
I was also facing issue while importing matplotlib but it got resolved and now I am able to use it from pycharm as well.
Please make sure you should have visual c++ 14 installed in your system.
2.If you have more than two python version installed on your system then please install matplotlib from both the version.
Eg. pip install matplotlib
pip3 install matplotlib
If matplotlib is working from python idle then please check whether you are using correct interpreter in pycharm or not and try to choose pythonw.exe path from your installed location.
Hope this will help, Please do let me know if you are still facing issue.
I had similar issue but I solved it very easily on pycharm 2019.3.2. In case anyone looking for an easier solution:
I just opened the terminal window on pycharm and typed pip install matplotlib and it was all good to go. Every project has its own virtual environment. Opening terminal window of IDE cds to project directory by default. So the installing command was enough.
I am using Ubuntu 15.04 and I just installed IPython 4.0.
Now, when I type ipython notebook in the terminal, I get the following error message:
ImportError: No module named notebook.notebookapp
I have read related questions on this site but I could not solve this situation.
Since, I have no working knowledge of IPython,so I could really use some advice to fix this.
Try pip install "ipython[notebook]"
and take a look here:
http://ipython.org/install.html#i-already-have-python.
This should install all the dependencies and get you up and running.
I just tried to use pd.HDFStore in IPython Notebook with a Python 3 kernel (Anaconda 2&3 on Ubuntu 14.04)
import pandas as pd
store = pd.HDFStore('/home/Jian/Downloads/test.h5')
but it throws the following error
ImportError: HDFStore requires PyTables, "libhdf5.so.9: cannot open shared object file: No such file or directory" problem importing
I initially thought it's because pytables is somehow missing, but when I check $source activate py34 and $conda list, pytables 3.2.0 is already installed under anaconda python3 environment.
Also, if I switch to Python 2, for example, $source activate py27 and start ipython notebook, it works properly and no import error is thrown.
I guess that I must miss something for configuring pytables under anaconda python 3 env, but I cannot figure it out. Any help is highly appreciated.
Update:
I just tried on a fresh install of Anaconda3-2.3.0-Linux-x86_64 from official website and it ends up with the same error. When I try $locate libhdf5.so.9 in command line, nothing shows up.
This is a known issue that we are working on. When it is fixed, conda update --all will update the libraries and fix the issue.
