FAILED: meson-install - gnome

I want to install the totem app from the source GNOME code.
I cloned source code for totem app from GNOME github, and compiled with messon and ninja commands, and all of that was successfully compiled.
The problem is when I call command meson install, at one point it breaks off.
The steps I followed:
git clone https://github.com/GNOME/totem.git
cd totem
meson builddir
ninja
ninja test
cd ..
meson compile
cd builddir
sudo ninja install
Error which occured:

Note: I tried on two PC (ubuntu 20.04), and on one PC it works, and other I got an error.

It looks you are missing one of the build dependencies for totem: itstool (converts xml localization (language translations) data); dependent through usage of i18 module here. You can install it with
sudo apt-get install itstool
Here is the list of other required dependencies (latest or another package versions may or may not work though).

Pyinstaller error: 'SystemError: codesign failure!' on macOS

I have made an application that I am now distributing on macos and windows (windows successfully compiled) but when I try to compile my app it keeps throwing the error SystemError: codesign failure! In pyinstaller I am using the --onefile flag, and I have tried it without the flag (python pyinstaller.py app.py, I could not use python pyinstaller app.py as I was thrown command not found). This is the full error message:

Since I have never compiled an app for mac and this is my first time doing it, I have no idea what this really means. This is using python 3.9.
This seems to be an issue with the way pyinstaller performs ad-hoc signing since codesigning changed sometime after 4.3 (see https://github.com/pyinstaller/pyinstaller/issues/6167). Building on the latest Big Sur (MacOS 11.5.2) should work fine but I assume you're on Catalina or earlier.
You can either:
Downgrade to pyinstaller 4.3 with pip uninstall pyinstaller and pip install -Iv pyinstaller==4.3 and then rebuild as you were.
or
Provide a certificate to sign the app yourself.
If you want to sign the app yourself you can do so like so:
Open Keychain Access
Go to the menu at the top of the screen and select Keychain Access > Certificate Assistant > Create a Certificate
In the window that appears change Certificate Type to Code Signing , select Create and note the name of the certificate
Build your pyinstaller source with the --codesign-identity <name> flag where <name> is the name of the certificate you created in step 3.

How can I install Python 3.7 on an old centos shared web host (without root)?

I want to install Python 3.7 on a web hosting server that is live (production) without disturbing anything. I have SSH terminal access and I guess the server is running centos from the following commands:
> cat /proc/version
Linux version 3.10.0-693.11.6.1.ELK.el6.x86_64 (...) (gcc version 4.8.2 20140120 (Red Hat 4.8.2-15) (GCC) )
> rpm -qa centos-release
centos-release-6-10.el6.centos.12.3.x86_64
I tried to see what was installed with:
> rpm -qa | sort
...
Python27-2.7.8-1.x86_64
Python27-MySQL-1.2.3-2.el6.x86_64
Python27-bs4-4.1.3-1.noarch
Python27-distribute-0.6.32-1.noarch
Python27-lxml-3.0.1-1.x86_64
Python27-pip-1.2.1-1.noarch
Python27-regex-0.1.20120904-1.x86_64
Python27-virtualenv-1.8.4-1.noarch
Python3-3.2.3-1.x86_64
Python3-distribute-0.6.32-1.noarch
Python3-pip-1.2.1-1.noarch
Python3-virtualenv-1.8.4-1.noarch
...
So it looks like there's Python 2.7 and 3.2 already installed, and I don't want to disturb them.
I want to run a Python 3.7 script with dependencies on some modules.
What is the safest way of installing Python 3.7 (along with pip for modules) somewhere that will not mess with the current installation?
NOTE: I am familiar with conda/pip mostly on Windows, but I have limited knowledge of this linux environment.
EDIT: I first thought it was RHEL. I edited the post for centos.
EDIT: I have tried many unsuccessful attempts to install Python 3.7 on this shared web hosting:

You can use venv to completely isolate your python environment from all other python versions (and python libraries) installed in the system.
Read the virtual environment, venv, docs here.

Caffe2 doesn't seem to see cuDNN?

I am trying to install SpConv (spatially sparse convolution library), however when running python3 setup.py bdist_wheel, I get an error which seems to be related to Caffe2 not being able to see cuDNN, as I infer from this message:
CMake Error at /home/ivan/.local/lib/python3.6/site-packages/torch/share/cmake/Caffe2/Caffe2Config.cmake:96 (message):
Your installed Caffe2 version uses cuDNN but I cannot find the cuDNN
libraries. Please set the proper cuDNN prefixes and / or install cuDNN.
I have tried reinstalling cuDNN but no luck. Can I manually point Caffe2 to cuDNN? This is because usually cuda is located in /usr/local/cuda/, however I have it in /usr/lib/cuda.

System: Ubuntu 18.04, CUDA 9.1, cuDNN 7.6.3
Found the problem. I needed to set CUDNN_INCLUDE_DIR to /usr/lib/cuda/include (i.e. where the cudnn.h file is located).
Lesson learnt: take time to understand the error, missing: CUDNN_INCLUDE_DIR was key.
Another way to fix this:
Acquire cuDNN from here. You may have to register to do this, but the registration is free.
Unpack the cuDNN archive file.
Move the cuDNN files as follows:
sudo cp cuda/include/cudnn*.h /usr/local/cuda/include
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*
Alternately, place a symoblic link at /usr/local/ pointing to the cuda directory produced by unpacking the cuDNN archive.

"can't combine user with prefix" trying to create zip package for function with dependencies

I am trying to make a deployment package with additional dependencies as per this guide https://docs.aws.amazon.com/lambda/latest/dg/lambda-python-how-to-create-deployment-package.html
I am doing this as a test, to see how simple it is. So i decided to try and import the first package that popped into my mind which was tldextract.
The guide tells me to make a fir called package, go into that package and then type "pip3 install tldextract --target ."
However, I get an error message:
distutils.errors.DistutilsOptionError: can't combine user with prefix, exec_prefix/home, or install_(plat)base
I have searched through this:
Combine --user with --prefix error with setup.py install
But to no avail.

You may have moved passed this, but just in case it helps (this drove me up a wall for the last half hour):
I'm running Debian and was trying to install pymysql, but try issuing the command with sudo:
sudo pip3 install tldextract --target .
I don't know why this worked yet, but will update with more info if I come across any. Files were installed in my local directory owned by root, which is unfortunate, but chown fixed that.

Slycot fails to import when using control

I then tried installing slycot with

raise ValueError("Symbol table not found")
ValueError: Symbol table not found
I read that this is due to a FORTRAN compiler not installed on the system. I therefore installed gfortran with Ming32. To verify the install I ran the following:
(base) C:\WINDOWS\system32>gfortran
gfortran: fatal error: no input files
compilation terminated.
So gfortran is installed as a compiler, but yet pip remain unable to install slycot. I have also installed Microsoft Visual Studio 2017.
At this point I went to PyPi library to download the compiled binary of the slycot module. https://www.lfd.uci.edu/~gohlke/pythonlibs/
Here I downloaded the correct .whl file for my system (64 bit Python 3.6), and installed it with pip.
pip install "C:\Users\Wian\Desktop\slycot-0.3.3-cp36-cp36m-win_amd64.whl"
Using this command slycot 0.3.3 was installed successfully. However, when i run the command
control.ss2tf(A,B,C,D)
I get the following output
---------------------------------------------------------------------------

ImportError: DLL load failed: The specified module could not be found.
There is a _wrapper.pyd file in the Slycot directory (under Anaconda3\Libs\site-packages).
This is where I am currently stuck, and I cannot get Slycot to import correctly.
Your help is greatly appreciated!
