Seahub fails to run initial start with ModuleNotFoundError

I'm currently trying to install seafile 7.1.4 on a Raspberry Pi 4 following the official guide (https://download.seafile.com/published/seafile-manual/deploy/using_mysql.md). The setup went smoothly, but when I try to start the seahub (./seahub start) for the first time I get the following error:
Traceback (most recent call last):
File "check_init_admin.py", line 351, in <module>
rpc = RPC()
File "check_init_admin.py", line 284, in __init__
import ccnet
ModuleNotFoundError: No module named 'ccnet'
I've been on google for the past two hours, but can't find a solution to this problem. What am I doing wrong?

I ran into the same issue. There's a bug in the 7.1.4 package. Seafile uses some local site packages. They (apparently) used to be under ${INSTALLPATH}/seafile/lib/python3.6/site-packages, now the are under ${INSTALLPATH}/seafile/lib/python3.7/site-packages
To fix:
open seahub.sh in the editor of your choice.
find the line that says:
export PYTHONPATH=${INSTALLPATH}/seafile/lib/python3.6/site-packages:${INSTALLPATH}/seafile/lib64/python3.6/site-packages:${INSTALLPATH}/seahub:${INSTALLPATH}/seahub/thirdpart:$PYTHONPATH
change it to read:
export PYTHONPATH=${INSTALLPATH}/seafile/lib/python3.7/site-packages:${INSTALLPATH}/seafile/lib64/python3.7/site-packages:${INSTALLPATH}/seahub:${INSTALLPATH}/seahub/thirdpart:$PYTHONPATH

How to bypass this regex error when downloading udemy videos

I am trying to download the entire course of videos from udemy.
After following the instructions and getting the necessary packages installed, I get the error below :
Traceback (most recent call last):
File "/usr/local/bin/udemy-dl", line 7, in <module>
main()
File "/usr/local/lib/python2.7/dist-packages/udemy_dl/udemy_dl.py", line 837, in main

return match.group(1)
AttributeError: 'NoneType' object has no attribute 'group'
I am using linux 18.04 and I have installed python 2.7 already. I can be successfully authenticated to udemy from the command line but I am not able to get the videos. Does anyone know how can I get solve this regex error?

Instead of struggling with this python module, you can use this package

No need to deal with python and no need to install just get the executable files from library bin folder and you are ready to go.

Problem occurred when using PyTesseract to recognize text from an image

I was trying to make an automatic login program for our school website, which requires recognizing text from a captcha code. So I installed pytesseract from pip, and ran the program in PyCharm: (the image is in the directory /Users/macintosh/Documents/PythonOutputs/2.jpg)
import pytesseract
from PIL import Image
image = Image.open("/Users/macintosh/Documents/PythonOutputs/2.jpg")
text = pytesseract.image_to_string(image)
print(text)
But this error occured:
Traceback (most recent call last): File
"/Users/macintosh/Library/Preferences/PyCharmCE2018.2/scratches/scratch_3.py",
line 5, in
text = pytesseract.image_to_string(image)
File
"/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pytesseract/pytesseract.py",
line 294, in image_to_string
return run_and_get_output(*args)
File
"/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pytesseract/pytesseract.py",
line 202, in run_and_get_output
run_tesseract(**kwargs)
File
"/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pytesseract/pytesseract.py",
line 178, in run_tesseract
raise TesseractError(status_code, get_errors(error_string))
pytesseract.pytesseract.TesseractError: (2, 'Usage: python
pytesseract.py [-l lang] input_file')
What's the problem?

Well, although your error message is not really crystal clear I bet (judging from your actions) you haven't installed Tesseract itself.
In pytessaract documentation it states that:
Python-tesseract is a wrapper for Google’s Tesseract-OCR Engine.
so you should install the actual program (Tesseract that is) to do the job also.

PIL with Centos 7 and Python 3.4

Does anyone have a working implementation of PIL with Centos 7 and Python 3.4?
I tried to install the tarball from here, but when running "make" or "make test" got a lot of errors.
If anyone has a working implementation, could you please post the commands and configuration needed i.e. yum packages to get it to work?
I also found this blog post but it didn't help.
Here is one error that I am seeing when trying to convert a jpeg's size:
Traceback (most recent call last):
File "<console>", line 2, in <module>

File "/var/www/deploy/myproject/myproject-django/venv/lib/python3.4/site-packages/PIL/ImageFile.py", line 203, in load
d = Image._getdecoder(self.mode, d, a, self.decoderconfig)

raise IOError("decoder %s not available" % decoder_name)
OSError: decoder jpeg not available

Make sure you install the dependencies first, and then reinstall Pillow. Looks like you're missing libjpeg. See here for details.
