Unable to install pyaudio on osx lion - osx-lion

I'd like to install pyaudio on osx lion but i'm unable to do it. Everytime i try with the pkg, it doesn't install anything. When i try to install it with pip i have the following error (among a lot of other lines) :
lipo: can't open input file: /var/folders/11/gfpzwjdd6dj7hbz7dpbvx9y40000gn/T//ccYnQM1k.out (No such file or directory)
error: command '/usr/bin/llvm-gcc' failed with exit status 1
If anyone can help me, thank you.

I had to manually install it to get anything working. You'll need the source distributions for both pyaudio and portaudio.
Firstly I installed portaudio with MacPorts (not from the source distribution):
sudo port install portaudio
pyaudio then refused to install as it couldn't find the pa_mac_core.h and portaudio.h headers. After copying these from the portaudio source distribution include folder into pyaudio's src folder, I had to uncomment line 49 of pa_mac_core.h:
#include <AudioToolbox/AudioToolbox.h>
Doing this allowed me to get pyaudio to install using a simple
sudo python setup.py install
(I probably didn't need superuser for the portaudio install, but pyaudio wouldn't install unless I did it as a superuser)

How can i use PIL in python?

I have successfully installed Pillow:
chris#MBPvonChristoph sources % python3 -m pip install --upgrade Pillow

Successfully installed Pillow-9.0.1
but when i try to use it in pycharm got:
Traceback (most recent call last):
File "/Users/chris/PycharmProjects/pythonProject2/main.py", line 1, in
from PIL import Image
ModuleNotFoundError: No module named 'PIL'
or using in Blender i got:
ModuleNotFoundError: No module named 'PIL'
I am not a python lib installing pro...so obviously i made something wrong. But how do i fix that?
Maybe i have to say i am working on a M1 Macbook
looks like you may need to repoint your pycharm to your installed python interpreter.
go to command line and find out python interpreter path. On windows you can where python in your command line an it will give you where your python and packages are installed.. You could also activate python directly in command line and find paths from there. For example, open command line then;
python
press enter = activates python
within then you can do:
import sys
for x in sys.path: x
In pycharm make sure you point to path discovered from step 1 and select that to be your python interpreter within pycharm --- check out examples here https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#add-existing-interpreter
Should work. Not sure about all the steps you took, but if you installed python with pycharm on top of your regular installation of python i would recommend :
finding all the paths from step 1
deleting python using system
checking if folders found from paths step still exist
if they do, delete those as well
start over just with one python installation
repoint to that in pycharm
first
pip uninstall PIL
after uninstall
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
or
brew install Pillow

Installing Vivado ML 2021.2 in CentOs but process is hang in 'Generating installed device list'

anybody can help me figure out why the installation is hanging on 'Generating installed device list' and how to solve it without starting the process all over. I am working on CentOs.
Thanks in advance
I think this happens due to following missing packages:
libstdc++6:i386
libgtk2.0-0:i386
dpkg-dev:i386
ncurses5-compat-libs
python3-pip
libtinfo5
libncurses5
As BKN mentioned, you need to install the missing packages.
To avoid starting all over again, you can do the following:
Check the log: cat ~/.Xilinx/xinstall/*.log
Locate the error message. It should look something like:
2022-01-09 10:53:11,458 DEBUG: n.t:? - Executing script Generating installed device list: /tools/Xilinx/Vivado/2021.2/bin/vivado [-nolog, -nojournal, -mode, batch, -source, /tools/Xilinx/Vivado/2021.2/scripts/sysgen/tcl/xlpartinfo.tcl, -tclargs, /tools/Xilinx/Vivado/2021.2/data/parts/installed_devices.txt]

The log informs you exactly what the missing package is (in this case it was libtinfo), and also provides you with the script to run after you install the package:
/tools/Xilinx/Vivado/2021.2/bin/vivado -nolog -nojournal -mode batch -source /tools/Xilinx/Vivado/2021.2/scripts/sysgen/tcl/xlpartinfo.tcl -tclargs /tools/Xilinx/Vivado/2021.2/data/parts/installed_devices.txt
Notes:
Make sure to use the Vivado version (here it was 2021.2) and location (here it was /tools/Xilinx) according to your system.
You may need to run the script in sudo if the the permissions for writing are not available in user mode.
I also encounterd this problem on Archlinux with Vivado 2018.3.
But I just installed the library ncurses5-compat-libs, then the problem is solved.
Perhaps you can solve this by checking the library ncurses5-compat-libs.
Download the tar package instead of the self-extracting bin package
Update the java and python version
sudo apt-get install -y python3-pip
Install Dependencies
sudo apt-get install -y libstdc++6
sudo apt-get install -y libgtk2.0-0
sudo apt-get install -y dpkg-dev
NOTE: Without ibtinfo5 the application will not start and without libncurses5 the simulation will fail
`sudo apt-get install -y libtinfo5 libncurses5`
Restart the system
Untar that Vivado package
tar -xzvf Xilinx_Unified_2021.2_1021_0703.tar.gz
Locate the xsetup file in the package
Install the package in batch mode
./xsetup --agree 3rdPartyEULA,XilinxEULA --batch Install --product "Vivado" --edition "Vivado ML Enterprise" --location "/home/USER"
Once the installation has been successfully completed
Locate the settings64.sh file
./settings64.sh
Locate the cable drivers
cd Vivado/2021.2/data/xicom/cable_drivers/lin64/install_scripts/install_drivers
./install_drivers
Installing Vivado Board Files
Get the board package from the git https://github.com/Digilent/vivado-boards.git
From the vivado-board-master package copy the folder board_files undert /vivado-board-master/new/board_files
Paste the board files to Vivado/2021.2/data/boards
From the vivado-board-master package copy the file Vivado_init.tcl under /vivado-board-master/utility
Paste the file Vivado_init.tcl to the Vivado installation
That's it!! You might not need to do all these steps but that is what I ended up doing and it worked for the two machines where I installed Vivado. The installation took less than one hour.
This was originally edited into the question itself by the OP.

pyrcc5: No such file or directory

I want to install labelImg for mac OS in python 3.7. here is the repo: https://github.com/tzutalin/labelImg
I have installed previous modules via 'pip3 install pyqt5 lxml' successfully. Cloned the repo, entered the folder 'labelImg', but only 'make qt5py3' does not work..
but when I execute 'make qt5py3', i get the error
pyrcc5 -o libs/resources.py resources.qrc
make: pyrcc5: No such file or directory
make: *** [qt5py3] Error 1
What can I do here? What might have caused the issue?
-find 'pyrcc5' under python bin, and copy 'path'
-under labelImg find 'Makefile' and edit
-change line
qt5py3: pyrcc5 to qt5py3: 'copied path'/pyrcc5
and save
-and
make qt5py3
python labelImg.py
should works.
I had the same issues as the OP, but with Python 3.6.11. In addition, I got ModuleNotFoundErrors for pyqt5 and libxml2, even though brew confirmed they were both installed. Also, I was trying to install in a virtual environment set up using pyenv.
What finally worked for me was:
1) use global env, not virtual
2) use pip (not pip3) to install pyqt5 and lxml
3) change the makefile as #zippo suggested
After I did that, I was able to get labelImg to start by running:
python labelImg.py

Install perl module Net:SSH2 on redhat/centos 7

As the title says I am trying to install the perl module perl-Net-SSH2. I have tried via yum but get an error that no package is available.
yum install perl-Net-SSH2
I have tried by downloading an rpm file but the only one I can find is for el6 and it complains about the version of perl
yum localinstall perl-Net-SSH2-0.45-4.el6.x86_64.rpm
Requires: perl(:MODULE_COMPAT_5.10.1)
I have tried downloading the source code but get told "Unable to find a working version of library ssh2 in the following directories" even though it is installed. (via yum install libssh2 libssh2-devel)
I have tried via cpan but get the same error "Unable to find a working version of library ssh2 in the following directories"
Any ideas? Google is very sketchy on this and only
OK, I solved this while writing the question. Seeing as information on this is limited I thought it would be worth posting the question anyway. The error message was giving the wrong information in that it was actually gcc that was missing, not libssh2. These are the steps I followed. I've tried to make it as verbatim as possible. I have not verified all these modules are required but this is what I installed before compiling it.
yum install libssh2 libssh2-devel
yum install openssl openssl-devel
yum install perl-Net-SSLeay
yum install gcc
Search for Net::SSH2 in google
Click the link "Net::SSH2 - search.cpan.org"
Download source code (tar.gz file)
Copy it to your redhat 7 machine
tar -xvf Net-SSH2-0.62.tar.gz
cd Net-SSH2-x.xx
perl Makefile.PL
make
make install
Should all be working now, test it with
perl -e 'use Net::SSH2;'

How to install psycopg2 on windows 7

Now I am not able to understand what to do. Thanks
Edit 1:
I have also added my PostgreSQL path to system path variables
path:C:\Program Files\PostgreSQL\9.4
path:C:\Program Files\PostgreSQL\9.4\bin
The correct answer was given by Craig Ringer, I am just adding this because I came to know that we should first check which version of 64 bit or 32bit Python installed on our system. If you have 32 bit version of Python and if you will try to install 64bit, then you will get the above error on importing.
For checking the version:
import platform
platform.architecture()
and you will get an output like this:
('32bit','WindowsPE')
Download the pre-packaged binary release of psycopg2 for Windows rather than compiling it yourself. It's a pain to compile on Windows. This is explained in the install documentation for psycopg2.
You might need to remove your half-installed attempts.
Choose the appropriate version from this page:
http://www.stickpeople.com/projects/python/win-psycopg/
Right click and select copy link address
Back at home, use easy_install <<Paste URL Here>>
Freeze your new requirements: pip freeze > requirements.txt
Now that psycopg is in PyPI (as of March 2017 it appears), just fire up a command prompt with administrator privileges and install like so:
python -m pip install -U pip
python -m pip install psycopg2
If you don't have pip installed, follow the instructions here to do that first:
https://stackoverflow.com/a/12476379/2540707
pip install psycopg2-binary
This worked for me
Step 1: Compilers Installation and configuration
https://wiki.python.org/moin/WindowsCompilers
Before do anything, install or upgrade the Setuptools Python package. It contain compatibility improvements and add automatic use of compilers:
pip install --upgrade setuptools
Step 2: Download and install PostgreSQL
Before you continue to install python packages inside you virtualenvs download postgres itself. It contains files that are needed when compiling the psycopg2 python package. Just use the PostgreSQL installer(version 10 for example).
Important: add the postgres C:\Program Files\PostgreSQL\10\bin folder to your path. It contains the .dll needed for psycopg2.
Step 3: Install psycopg2
pip install psycopg2
Tested on Windows 7 + python 3.7
The best/easiest way of installing packages (including this problematic psycopg2 ) for python on windows platform is to:
1) install anaconda and ...
2) use Anaconda Navigator GUI to install/update packages.
By this one avoids many inconsistencies and conflicts that occurs among different packages versions and installations.
