I am trying to export a Julia Jupyter Notebook to pdf
I installed last version of Julia and VS Code (and the Julia and jupyter extension on VS Code)
I can do fine in jupyter notebooks, the code runs and it's saved on .ipynb format.
So this is what i've done:
In the cmd I just put
py -m pip install jupyter
py -m pip install nbconvert
But whenever I try to export the notebook from VS Code I get this error:
Error 2021-10-19 19:25:11: Export failed [Error: Importing notebooks requires Jupyter nbconvert to be installed.

Error 2021-10-19 19:25:11: If you have not installed xelatex (TeX) you will need to do so before you can export to PDF, for further instructions go to https://nbconvert.readthedocs.io/en/latest/install.html#installing-tex.
To avoid installing xelatex (TeX) you might want to try exporting to HTML and using your browsers "Print to PDF" feature.
I do have MikTex installed.
So I don't know what is going on.
Please, let me know how to export a jupyter notebook.
This is what the notebook looks like:
I have a similar problem than yours. The only difference, as I can guess, is that I'm using Mac and have TeXShop instead of MikTex. I have compiled .tex files using xelatex, so I think we both need to tell Visual Studio Code where is the xelatex file. I did a bit of research on the Internet and find suggestions to install the LaTex Workshop extension on VSC. It didn't solve the problem for me, but it'd work for you. I hope so. Let me know in that case.
Best,

I am getting the following error with plotnine==0.9 and matplotlib==3.6.
File "D:\Python\Python310\lib\site-packages\plotnine\stats\stat_density_2d.py", line 3, in <module>
import matplotlib._contour as _contour
ModuleNotFoundError: No module named 'matplotlib._contour'
If I downgrade matplotlib==3.5, the problem goes away.
It's discussed here and it's already fixed here Note that it's already merged to main.
It was due to a internal matplotlib call that is no longer supported and has been replaced.
So I guess you could choose between:
downgrade to mlp 3.5.3
install plotnine#main
till the next plotnine release.
Carlos's answer is correct. However if anybody else, like me, is uncertain of how to install plotnine#main, you can implement the fix rather easily:
Find the site_packages folder you python script uses. It usually is a subdirectory of the python version you are using, which can located reliably by trying to reinstall matplotlib or any other package you know you have access to, and checking the logs in the console. ex using python -m pip install matplotlib.
Go down into the site_packages/plotnine/stats directory and open up the stats_density_2d.py file in your editor of choice.
Apply & save the modifications made in the fix. Alternatively, overwrite the file with the one from the github.
ModuleNotFoundError: No module named 'matplotlib._contour'
Issues with matplotlib 3.6.1 and
plotnine 0.9.0
K.I.S.S.
in terminal:
pip show matplotlib #enables you to check version
pip install matplotlib==3.5 #revert and problem is resolved for now.
no more:
ModuleNotFoundError: No module named 'matplotlib._contour'
resolves issue for now that will stop progress...
I'm trying to use lcapy's python library to draw some electrical circuits in google colab. Unfortunately, I'm always getting an error:
RuntimeError: pdflatex is not installed
Even though I did pip install pdflatex
I couldn't find anything related to this error in lcapy's docs.
the notebook can be found here
I experienced a similar issue/error trying to render PDFs from latex output generated by pandas in google colab recently. The error I got was complaining about a file (Error Code 2), listed 'pdflatex' as the missing file, but I confirmed the install had completed as you reported. This led me to realize there were missing LaTex dependencies that were generating the error; the traceback seemed a bit misleading to me. Here is the solution that worked for me:
First, install components and dependencies in colab notebook:
!pip install folium==0.2.1
!pip install pdflatex
!sudo apt-get install texlive-latex-recommended
!sudo apt install texlive-latex-extra
!sudo apt install dvipng
In my first attempt, There was an error buried in the install of pdflatex with an incompatible version of folium 0.8.x, so the first command rolls it back to the compatible version from the error trace. Probably not totally necessary to roll back folium, but I haven't tested.
The latex install commands were shamelessly lifted from this answer for latex-equations-do-not-render-in-google-colaboratory-when-using-matplotlib, where they offer a bit more explanation. The whole install process produced quite a bit of output and took some time.
After completed, I was able to generate a pdf file from my LaTex string similar to the example from the package docs:
import pdflatex as ptex
pdfl = ptex.PDFLaTeX.from_texfile(r'/content/my_tex_string_file.tex')
pdf, log, completed_process = pdfl.create_pdf()
with open('testPDF.pdf', 'wb') as pdfout:
pdfout.write(pdf)
my_tex_string_file.tex was generated from pandas in my test case, and I added a preamble manually (string concatenation) to include the correct latex packages for my desired output, but a quick look through the github page for lcapy shows the same approach may work for lcapy as well.
I ran into the same issue myself and after verifying pdflatex is installed with !pdflatex -help, I looked into Lcapy's code. The easiest workaround I found is to comment out line 73 of system.py. I only need schematic tools, so this solution is adequate for me. If you need a proper solution, all the relevant functions are in the same file and it seems that import pdflatex is unnecessary as the library searches for the binary.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from "C:\USERS\YADAVP\ANACONDA3\python.exe",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.1" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: DLL load failed: The specified module could not be found.
What is the resolution to sort this kind of error in Power BI?
Forget Anaconda and use WinPython.
I tried Anaconda for days with all the workarounds available in StackOverflow and other forums, and they took me nowhere.
Then I tried WinPython, and it worked immediately. Of course, you will need to change the PowerBI options accordingly.
To install WinPython: https://github.com/winpython/winpython
To change the detected Python home directory: https://learn.microsoft.com/en-us/power-bi/connect-data/desktop-python-scripts#enable-python-scripting
If you consider my answer, you won't need to downgrade Python, PBI, or anything else.
I had the same error. Unfortunately, PowerBI wont work with Jupyter Notebook Python.
So you have to install a "normal" Python: https://www.python.org/downloads/
And configure the Python you want to use in PowerBI and install your needed Python libraries via pip
Edit: Please use Python 3.8 because 3.9 doesnt support NumPy for now
OS: window 10
Tensorflow version: 2.0.0
python: 3.7
After I installed tensorflow = 2.0.0, the error has occurred. When I open sublime text3, the error message pops up. It says
Anaconda.anaconda_lib.workers.local_process.LocalProcess object at Ox000001DE094E9DD8> process can not start a new anaconda JsonServer in the operating system because: Anaconda can not spawn a new process with your current configured python interpreter (python) Make sure your interpreter is a valid binary and is in your PATH or use an absolute path to it, for example: C:\Python27\python.exe
Actually, It doesn't shoot any trouble, when I run some python coding with tensorflow, but it's annoying..,
Every time I open sublime text, the error message comes out. When I do on pycharm, there is no error like this, and it works perfectly in terms of running tensorflow and anaconda.
I tried delete and install sublime text, but nothing has changed. Please help me.
Change Anaconda.sublime-settings User to have the following line (along with any other settings your might have)
{
"python_interpreter": "python3"
}
I had same issue, hope this helps.
I am using:
Thonny Version 3.2.1
Python Version 3.7.0
PIP Version 19.2.3
Pillow Version 6.1.0
I am trying to import an image into my program and show it on the screen with the below code:
I get the error:
ModuleNotFoundError: No module named 'PIL'
backend.py, line 276
I believe the problem isn't my code, but instead an issue with the module Pillow not being found by Python?
Can anyone please help with a fix? I can clarify any info needed.
Additionally, I am new to Python and so go easy on me :-) Apologies if any of my terminology is incorrect.
I have tried:
1\ Removing PIL as per the install warning from Pillow (PIL Fork) install info. It was not present on my system. I did this through CMD.
2\ I always access CMD as the administrator.
3\ Updating all program versions above through CMD.
4\ Info I’ve found shows the above versions are compatible.
5\ Using the code help('modules') to show available modules, it does not show 'PIL' or 'Image', but does show 'pip'.
6\ Checked many forums for other fixes.
from PIL import Image
im = Image.open("JC.png")
im.show()
