QUESTION
I recently uploaded an Django application with the use off Zappa, which was running perfectly fine.
Now, I wanted to update this application, and It suddenly gives me this error: (The changes I made wasn't really that much, removed a blank=True in my models.py)
...ANSWER
Answered 2022-Feb-09 at 11:13Don't exactly know what went wrong but I got it fixed by:
- completly removing my virtual environment
- creating a new one.
- installing packages with
pip install -r requirements.txt --no-cache-dir
the --no-cache-dir
was really important adding.
QUESTION
I have a docker container that requires a couple Python packages to be installed. I added some commands to install them, but the packages are not available in the container. I think I'm added them wrong, is there a certain way I need to copy over what was installed? Any help appreciated.
Specifically, I should be able to run lottie.py
in my container after installing it, but it does not exist, nor does pip3 even though the install is successful.
Below is my Dockerfile:

Answered 2021-Sep-09 at 15:16Was given help in the comments that I'm not copying anything over from the Python image. I was able to find python:alpine
and use that in my config below
QUESTION
I am generating figures for a paper in svg format, and when I export the ggplot to .svg, I obtain inconsistent panel border widths depending on the device I use to export. I need to use CairoSVG as some figures have symbols that the standard device does not generate properly.
It does not depend on the data, so here I am showing some dummy examples.
...ANSWER
Answered 2021-Sep-03 at 22:29This might just be because of how devices handle clipping masks. If you want the more consistent behaviour, you can try turning of the clipping for panels altogether. Below; a demonstration of how that affects the look of borders.
QUESTION
Sorry I know there seems to be a lot about this topic. But I do not see a real resolution?
I am trying to place a Django ecommerce pizza shop for learning Django on the website. Locally this works great no issues. I matched my environment locally to that on the ENV for the server. I got this issue resolved locally when I updated Cairo on my computer. So the emulated server works great.

I'm trying to extract text from images. Currently I'm getting empty string as output. Below is my code for pytesseract, although I'm open to Keras OCR also:-

Answered 2021-May-25 at 07:21The reason for keras-ocr
not working or returning nothing is because of the grayscale image (as I found it worked otherwise). See below:

QUESTION
I have this function that takes svg logos, converts them to png (first for loop), removes the extra redundant transparent pixels and saves it to its destination folder (second for loop).
...ANSWER
Answered 2021-Jan-29 at 23:01.getbbox()
returns a tuple of the left, right, upper, and lower coordinates. This is what is returned to the logo variable.
If you want to remove transparent portions of the image, use the following code:

QUESTION
I have .svg
files with metadata information, e.g., creator
, contributor
, licence
, and so on. Now, when I convert them into .pdf
I loose all these metadata and I see only cairo 1.14.6 (http://cairographics.org)
as Producer and Creator.
For conversion, I have tried both cairosvg 2.4.2 and inkscape 0.92.5. And all the .svg
metadata is lost. :\
I have two questions:
- Is there any method or application to convert
.svg
into.pdf
and preserve the metadata? - Or, alternatively, after converting, could I somehow transfer the metadata from
.svg
into.pdf
easily?
Thanks.
PS: Surprisingly, when I use Inkscape to transform from .svg
to .png
the metadata is preserved.
ANSWER
Answered 2020-Sep-28 at 11:03In the new Inkscape version 1.01
, most part of the metadata is preserved when converting from .svg
to .pdf
, while in the previous version, 0.92.5
, it was lost.
Thanks to @Moini for giving a hint in the release notes of Inkscape.
For Linux: Install the newest Inkscape version 1.01 using flatpak

Install CairoSVG
You can use CairoSVG like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
