I would like to run Blender in background mode (without the GUI) in the following manner:
blender myscene.blend --background --python myscript.py
Immediately after I run the command, Blender quits.
The output from the command shell appears below.
The same happens even if I don't pass the --python myscript.py argument.
What is the problem and how can I make Blender run in background mode?
I'm using Win7 64 bit.
Many thanks,
Igal

I know that this question has been asked a lot, but none of the suggestions seem to work, probably since my setup is somewhat different:
Ubuntu 22.04
python 3.10.8
tensorflow 2.11.0
cudatoolkit 11.2.2
cudnn 8.1.0.77
nvidia-tensorrt 8.4.3.1
nvidia-pyindex 1.0.9
Having created a conda environment 'tf', in the directory home/dan/anaconda3/envs/tf/lib/python3.10/site-packages/tensorrt I have
libnvinfer_builder_resource.so.8.4.3
libnvinfer_plugin.so.8
libnvinfer.so.8
libnvonnxparser.so.8
libnvparsers.so.8
tensorrt.so
When running python3 -c "import tensorflow as tf; print(tf.config.list_physical_devices('GPU'))" I get
tensorflow/compiler/xla/stream_executor/platform/default/dso_loader.cc:64] Could not load dynamic library 'libnvinfer.so.7';
dlerror: libnvinfer.so.7: cannot open shared object file: No such file or directory;

[PhysicalDevice(name='/physical_device:GPU:0', device_type='GPU')]
I'm guessing I should downgrade nvidia-tensorrt, but nothing I've tried seems to work, any advice would be much appreciated.
Solution: follow the steps listed here https://github.com/tensorflow/tensorflow/issues/57679#issuecomment-1249197802.
Add the following to ~/.bashrc (for the conda envs as described in my scenario):
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/dan/anaconda3/lib/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/dan/anaconda3/lib/python3.8/site-packages/tensorrt/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/dan/anaconda3/envs/tf/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/dan/anaconda3/envs/tf/lib/python3.8/site-packages/tensorrt/
For me the setting a symbolic link from libnvinfer version 7 to 8 worked:
# the follwoing path will be different for you - depending on your install method
$ cd env/lib/python3.10/site-packages/tensorrt
# create symbolic links
$ ln -s libnvinfer_plugin.so.8 libnvinfer_plugin.so.7
$ ln -s linvinfer.so.8 libnvinfer.so.7
# add tensorrt to library path
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/env/lib/python3.10/site-packages/tensorrt/
I'm compiling a program using the following commands on Linux Debian based:
i686-w64-mingw32-g++ -c my_program.cpp
i686-w64-mingw32-g++ -static-libgcc -static-libstdc++ my_program.o
But when I try to run the program inside my Windows 7 VirtualBox I get the following error:
libgcc_s_dw2-1.dll is missing
Why it doesn't static import the dll on compilation time?
Thank you
I'm attempting to get setup with a proper g++ installation according to the theano installation guide. I've previously had theano working with the python only implementation. I'm using the bleeding edge version of theano from their git repo on python 3.4. I've tried using the theano suggested TDM-GCC-64 method as well as MinGW, and both result in the exact same error. (copied as readable as possible)

^~~~~
It may be worth noting that before it prints this error, it prints an entire file worth of code, you can find the entire error output here
I'm not sure what to try next, I've followed the directions twice, used a couple different installation methods for some dependencies, and made sure to clean up my system path between each attempt and reboot.
This worked for me:
Go to your user folder: C:/Users/[username]
Create .theanorc file if it doesn't already exist
makes sure it includes the lines:
[gcc]
cxxflags = -D_hypot=hypot
"Error: '::hypot' has not been declared" in cmath while trying to embed Python
Error building Boost 1.49.0 with GCC 4.7.0
my solution is comment out all the
#define hypot _hypot
macro in the pyconfig.h file
This worked for me
Go to System properties/Advance system setting
Add your MinGW installation path, if already added and looks something like C:\{your MingW installation}\bin
change it to C:\{your MingW installation}
The answers above are probably a better, more permanent solution. For a quick fix, the following worked for me:
import theano
theano.config.gcc.cxxflags = "-D_hypot=hypot"
...with Windows 10, Anaconda 4.4, Python 2.7, Theano v0.10.0.dev1, m2w64-toolchain v5.3.0
if you can't create a file with name .theanorc.
You can use this code in console but before open cmd in C:/Users/[username] and then write python and then paste below code there:
import os
with open(os.path.join(os.environ["USERPROFILE"], ".theanorc"), "w") as f:
f.write("[gcc]\ncxxflags = -D_hypot=hypot")
First, uninstall all Theano versions.
Then:
pip install pydot-ng
conda install mingw libpython
pip install git+https://github.com/Theano/Theano.git#egg=Theano
I installed cx_Oracle on CentOS 6.2. When I import the library from the shell, it works fine but when I launch it through wsgi, I get the error :
ImportError: libclntsh.so.10.1: cannot open shared object file: No such file or directory
This is an environment variable problem : cx_Oracle does not find the path to the lib.
I have tried the solutions provided here
I have added a link to libclntsh.so.10.1 (with ln) in the /usr/lib directory
I have edited apache configuration and added :
ORACLE_HOME=/usr/lib/oracle/11.2/client64/lib
LD_LIBRARY_PATH=$ORACLE_HOME/
PATH=$ORACLE_HOME/bin:$PATH
I edited /etc/ld.so.conf and added :
/usr/lib/oracle/11.2/client64/lib
done after ldconfig
I tried to use python with :
os.env['ORACLE_HOME']='/usr/lib/oracle/11.2/client64/lib'
I edited the bashrc with :
export ORACLE_HOME=/usr/lib/oracle/11.2/client64/lib
export LD_LIBRARY_PATH=$ORACLE_HOME/
export PATH=$ORACLE_HOME/bin:$PATH
I also edited apachectl with
ORACLE_HOME=/usr/lib/oracle/11.2/client64/lib
export ORACLE_HOME
LD_LIBRARY_PATH=$ORACLE_HOME/
export LD_LIBRARY_PATH
PATH=$ORACLE_HOME/bin:$PATH
export PATH
I am running out of ideas. Any suggestions ?
When you compile the Python module for Oracle, set:
LD_RUN_PATH=/usr/lib/oracle/11.2/client64/lib
user environment variable and export it. This will cause that directory to be embedded in Python extension module .so file and will know where to find it at run time without needing to set LD_LIBRARY_PATH environment variable.
For a standard Apache distribution (Linux distros are often a bit different), the file to set extra environment variables in is called 'envvars' and is in same directory as 'httpd'. For Linux distros often needs to be in a special init.d startup script.
So, lookup what LD_RUN_PATH is all about.
Instead of using yum install on the cx_Oracle rpm, I downloaded the source of the library and run the setup.py build.
I got an error that would point me to the function that was trying to locate the instant client sdk libraries in :
possibleIncludeDirs = ["rdbms/demo", "rdbms/public", "network/public","sdk/include"]
Browsing the Oracle_home folder, i discovered that the sdk file where installed in the lib folder ( I installed the skd using yum install on the rpm from oracle ) and not in the possibleIncludeDirs or in an include folder as suggested in the setup.py :
if not includeDirs:
path = os.path.join(oracleLibDir, "include")
if os.path.isdir(path):
includeDirs.append(path)
if not includeDirs:
path = re.sub("lib(64)?", "include", oracleHome)
if os.path.isdir(path):
includeDirs.append(path)
I downloaded the instant client sdk (the zip file this time) and unziped it to the lib folder.
There was then a sdk folder in the lib folder (/usr/lib/oracle/11.2/client64/lib)
I then launched the setup.py build and setup.py install and it worked.
I asked a question a couple of days ago regarding installing numpy on the same system. Thankfully, I managed to solve that one myself but unfortunately I am now stuck trying to install matplotlib.
I first of all tried the current distributed version but had no luck with that so I thought i would download the git repository and try that. I have got this far:
changed the make.osx file so that it will work in Python 3:
import urllib -> import urllib.request
urllib.urlretrieve() -> urllib.request.urlretrieve()
Even after that I still had a problem with it not finding the freetype2 headers. I googled around and discovered that I could solve this by editing a line in setupext.py:
'darwin' : [], -> 'darwin' : ['/usr/local'],
However, I still get an error message when using the make.osx file. Here is how I am calling the file from Terminal:
sudo make -f make.osx PREFIX=/usr/local PYVERSION=3.2 fetch deps mpl_build mpl_install
I realise that matplotlib isn't officially supported on Python 3 yet but I thought that maybe someone somewhere as at least managed to get it to compile/install?
Any help would be much appreciated,
Adam.

Okay...I think have managed to get matplotlib to install now...
First of all you need to install numpy. I have instructions to do this on another post: install numpy
Now open Terminal and clone the git repository for matplotlib (assumes you have git installed):
git clone git://github.com/matplotlib/matplotlib.git (this might take a while)
Once the clone is complete open your user folder in Finder
In your user folder open the matplotlib directory
There is a file called `make.osx' open this with TextEdit (or similar)
Change the following lines:
MACOSX_DEPLOYMENT_TARGET=10.6
OSX_SDK_VER=10.6
To:
MACOSX_DEPLOYMENT_TARGET=10.7
OSX_SDK_VER=10.7
Change the following lines:
${PYTHON} -c 'import urllib; urllib.urlretrieve("${ZLIBURL}", "${ZLIBFILE}")' &&\
${PYTHON} -c 'import urllib; urllib.urlretrieve("${PNGURL}", "${PNGFILE}")' &&\
${PYTHON} -c 'import urllib; urllib.urlretrieve("${FREETYPEURL}", "${FREETYPEFILE}")'
To:
${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${ZLIBURL}", "${ZLIBFILE}")' &&\
${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${PNGURL}", "${PNGFILE}")' &&\
${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${FREETYPEURL}", "${FREETYPEFILE}")'
Save the changes
Open the file called setupext.py in idle
Find the line 'darwin' : [], and change it to 'darwin' : ['/usr/local'],
Save the file
Open Terminal again and type the following:
sudo make -f make.osx PREFIX=/usr/local PYVERSION=3.2 fetch deps mpl_build mpl_install
After some time matplotlib should be installed in the following directory:
/usr/local/lib/Python3.2/site-packages/
Open the above directory and also the following directory:
/Library/Python/3.2/site-packages/
Copy/move the following directories from /usr/local/lib/Python3.2/site-packages/ to /Library/Python/3.2/site-packages/:
dateutil
matplotlib
mpl_toolkits
matplotlib should be now installed
If you open idle and type import matplotlib it shouldn't return an error
I tried out the matplotlib/examples/user_interfaces/embedding_in_qt4_wtoolbar.py file and it seems works fine
Hope someone else finds this useful!
Thanks again for the assistance,
Adam.
