I have downloaded Mayan EDMS-Electronic Document Management System from GitHub and I configured project using Django server. I had added the required libraries based on requirement. Now the project runs with error
ocr.exceptions.OCRError: No OCR tool found
When I searched this error, I found Pyocr looks for the OCR tools (Tesseract, Cuneiform, etc) installed on your system and just tells you what it has found.
Then I tried to install tesseract using the command -->pip install tesseract-ocr.
I got this error

please help me to solve this issue. Thanks in advance.
Tesseract is installed on the OS using the apt-get command. The command you are using (PIP) is for installing Python packages, that is the reason for the error.

I want to install pandas on docker image containing python. I used the code below to run a container:
docker run -p 8888:8888 -v /home/DATA/Project_NY/:/home/jovyan/work/Project_NY jupyter/scipy-notebook
I created a new notebook and then tried to install my requirements file doing pip install -r "requirements.txt" i got the error below and when I tried to pip install pandas inside that running container it works perfectly:
requirements.txt content

pandas==0.25.0
docker==3.3.0
python-json-logger
sshtunnel==0.1.4
jupyter
jupytext==0.8.4

the error is

ERROR: Failed building wheel for pandas
It seems like the pandas version you are trying to install needs a custom build for the System you're using as Dockercontainer.
You should get the same error if you run pip install pandas==0.25.0 inside the container.
Either use a different version of pandas or install gcc in the container ( e.g.: for alpine, inside Dockerfile CMD apk add --no-cache --virtual .build-deps gcc).
EDIT: I think the 'jupyter/scipy-notebook'-image uses conda, so maybe try:
docker run -p 8888:8888 -v /home/DATA/Project_NY/:/home/jovyan/work/Project_NY jupyter/scipy-notebook conda install gcc
the conda install gcc in the end is executed inside the container.
I am trying to run Quantlib-Python on a Macbook with M1 processor (Big Sur v11.3) following https://www.quantlib.org/install/macosx-python.shtml. I have managed to install Quantlib 1.22 and Python 3.9.4 via homebrew:
Pouring quantlib--1.22.arm64_big_sur.bottle.tar.gz into "/opt/homebrew/Cellar/quantlib/1.22"
However when I then try to install Quantlib-Python through pip I get:
ERROR: Could not find a version that satisfies the requirement QuantLib (from versions: none)
ERROR: No matching distribution found for QuantLib
From this it seems that whilst Quantlib 1.22 is ready for arm-based OSX, QuantLib-Python isn't.
Then I am trying to install from a released version as per the above link:
tar xzf QuantLib-SWIG-1.22.tar.gz
cd QuantLib-SWIG-1.22/Python
export CXXFLAGS='-O2 -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.9'
export LDFLAGS='-stdlib=libc++ -mmacosx-version-min=10.9'
python setup.py build
But I get the following error:

I have tried quite a few workarounds for the boost issue, and looked over lots of other question/answers but yet to find a fix. Is it an issue with the flags? Has anyone had any luck getting QuantLib-Python to work on M1-based OSX?
Below worked for me on a MBP M1 Max:
brew install boost
brew install quantlib

i have kubuntu 15.10 with python2.7 and python 3.4m installed
if i install cxfreeze with sudo apt-get cx_freeze it is installed with no issues but the problem is when i compile my python modules the are compiled for python2.7 not python 3
So i am trying to build cx_freeze from source and i am facing this error when i run sudo python3 setup.py build
here's the error

Install zlib1g-dev :
sudo apt install zlib1g-dev
then install cx_freeze for python:
pip install cx_freeze
I've tried that on Ubuntu 18.04 and Python 3.6 and worked.
I had exactly the same problem. As suggested in this answer you just need to install the dependencies first:
pip3 install zlib1g-dev
Then sudo python3 setup.py build
This project work fine on my local Ubuntu 12.04 and Mac OSX 10.10 (with fink python) machines. I can't seem to figure out how to configure the .travis.yml to get the .cpp files to build with g++-4.8 (4.9 or 5.x) would be fine too.

Thanks Dominic. I tried printing things and that was helpful. That got me thinking that I could just get explicit and force python to use the correct compiler. That makes it easier to see what is happening.
install:
- sudo apt-get install -qq gcc-4.8 g++-4.8
- CC=g++-4.8 python setup.py install
Which works.
I tried:
sudo yum install libxml2-dev libxslt-dev python-dev
and I got:

pip did not work either.
I got the package like this:

Then I tried without cython because sudo python setup.py install gave me RuntimeError: ERROR: Trying to build without Cython, but pre-generated 'src/lxml/lxml.etree.c' is not available
sudo python setup.py install --without-cython
Then I got:

It really wants me to make sure the development packages of libxml2 and libxslt are installed.
If I can do that I hope it will work. Any ideas? Thanks! It seems people have related issues to this, but most are on other systems.
UPDATE:
Based on Vor's suggestion I used the -devel extension and that worked to install the dependencies.
sudo yum install libxml2-devel libxslt-devel python-devel
Unfortunately I get this:
$sudo python setup.py install --without-cython

I had the same problem. After this line:
sudo yum install libxml2-devel libxslt-devel python-devel
I tried again with
sudo yum install lxml
And it worked :)
The problem on EC2 t.micro is that you run out of memory to compile the lxml package.
When you run: dmesg | tail you will see the issue
[167588.470868] Out of memory: Kill process 9804 (cc1) score 499 or sacrifice child

The only way is to install the python-lxml package via yum or other package manager.
sudo yum install libxml2-devel libxslt-devel python-devel
add
sudo yum install gcc
and this worked for me.
Add on to huapito's answer. Following code work for me.
sudo yum install gcc libxml2-devel libxslt-devel python-devel
sudo pip install lxml
On CentOS it is python-devel, not python-dev. Same thing with others.
The following worked for me:
sudo yum install libxml2-devel libxslt-devel python-devel
On AWS EC2 instance:
Amazon Linux AMI release 2015.09
Broken build left intermediate files in the process. try
rm -rf /tmp/pip-build-root
On my AWS machine I had both python2.7 and python3.4 and I was looking to install lxml for python3.4 - I found that I had to use
sudo yum install python34-devel
