Using Buildozer I get 12 times:
#error Do not use this file, it is the result of a failed Cython compilation.
And eventually:
Command failed: ./distribute.sh -m "kivy" -d "myapp"
According to the Kivy docs, I use Cython 0.21.2.
See the full log.
Any help would be very much appreciated!
Looks like you have Kivy 1.8.0 installed, and you're building Kivy 1.9.0 with buildozer. You will need to uninstall or upgrade your system Kivy. This is a bug in Cython, because it is using the system-installed pxds before the local directory pxds.

I am trying to install pytorch for using BERT but when following the installation instructions found here: https://pytorch.org/get-started/locally/ I am getting an error.
When I try and initalise the BERT model I get the following error:
ImportError:
BertForSequenceClassification requires the PyTorch library but it was not found in your environment.
Checkout the instructions on theinstallation page: https://pytorch.org/get-started/locally/
and follow the ones that match your environment.
I have followed the instructions and run the following command line in my Conda prompt terminal AND in my current working directory:
conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch
It looks to complete but when I try and call the following line I get the same error as the start as if it hasn't installed at all.
Can anyone help me out please.
EDIT:
The code I am using to execute bert is:
model = BertForSequenceClassification.from_pretrained(r'C:\Users\441\bert\pytorch_model.bin', config = r'C:\Users\441\bert\config.json')
I had the same issue (same error msg), and after using conda list | grep torch I also found it is there. What worked for me is that I restarted the jupyter notebook kernel and the error is gone.
I tried a lot of things I read on documentations or tutorials... But I still can't cross-compile Qt with the MySQL library driver. Story begins:
I have to cross-compile Qt from Linux to Windows (32bits) using MinGW (i686-w64-mingw32- prefix to be precise). I downloaded qtbase-opensource-src-5.9.4 and started to work like that:
$ ./configure -prefix [...]/qt-5.9.4 -xplatform win32-g++ -device-option CROSS_COMPILE=/usr/bin/i686-w64-mingw32- -opengl desktop -no-sql-odbc -sql-sqlite -enable-shared -nomake examples -nomake tests -release
And it worked. Then, make and make install worked too. But I figured out that there was only the SQLite ".dll" in the plugins/sqldrivers repository. So I tried to compile the MySQL driver and... How can I do that?? If I add -sql-mysql to my ./configure ... call, I have to following error:
ERROR: Feature 'sql-mysql' was enabled, but the pre-condition 'libs.mysql' failed.
I downloaded MySQL library from the official website to get mysql-5.7.21-win32.zip. But how to link it with qtbase sources? Adding MYSQL_INCDIR=[...]/mysql-5.7.21-win32/include and MYSQL_LIBDIR=[...]/mysql-5.7.21-win32/lib or just MYSQL_PREFIX=[...]/mysql-5.7.21-win32 to my ./configure ... command results to the same error message.
Any idea please?
EDIT:
I tried to compile the driver like that (with the qmake I built previously):
$ cd qtbase-opensource-src-5.9.4/src/plugins/sqldrivers/mysql
$ [/*prefix of my previous build*/]/qt-5.9.4/bin/qmake .
And the result is:
Project ERROR: Library 'mysql' is not defined.
Ok everyone, I found the solution: do a clean checkout or add -recheck-all to the ./configure command when you want to add a lib like MySQL in my case. Easy isn't it? To make it clear, here is the command I used:
./configure -prefix [...] -xplatform win32-g++ -device-option CROSS_COMPILE=/usr/bin/i686-w64-mingw32- -opengl desktop -no-sql-odbc -sql-sqlite -plugin-sql-mysql MYSQL_PREFIX=[...] -enable-shared -nomake examples -nomake tests -release -recheck-all
That was just a refresh problem, but I prefer to let this answer because it's pretty hard to realize.
Instead of what you tried in your EDIT, should I think be:
$ cd qtbase-opensource-src-5.9.4/src/plugins/sqldrivers
qmake -- MYSQL_PREFIX= [...]/mysql-5.7.21-win32/include
Can someone pinpoint where I'm doing wrong, PLEASE? I'm so exhausted. I installed MinGW 4.7, python2.7.8, numpy 1.7.1 and scipy0.13.2 to an Anaconda (32bit) environment in Windows7.
Also, for user enviroment variables, I set
C_INCLUDE_PATH:
D:\Anaconda2\envs\arc103\MinGW\i686-w64-mingw32\include
Path (User variable):
C:\Program Files (x86)\Microsoft VS code\bin;D:\Anaconda2\Library\bin;D:\Anaconda2\envs\arc103\MinGW\bin
Tying the following commands in Anaconda Prompt
"f2py -c --help-fcompiler" outputs "... Fortran compilers found:
--fcompiler=gnu95 GNU Fortran 95 compiler (4.7.0) ...."
"f2py -c --help-compiler" outputs
"List of available compilers: ...", not specifically compilers found though.
Running "f2py -c fib1.f -m fib1" according to "NumPy v1.12.dev0 Manual" gives me lots of error as below:

Sorry for the mess. I have spent almost a few months finding out the fix, but it's too hard for me and all gone to no avail. It would be hugely appreciated if you can help me out. Thanks.
Since this is a couple month old, I am not sure if these tips will still help, but I found when building a Fortran to Python module on Win 10, that only compiling for 32bit worked, and you need to use a signature file, i.e. something along the lines of:
f2py.py -c cuncsd.pyf cuncsd.f
Instead of using the i686-w64-mingw32 toolchain I used a straight mingw32 one (to reduce the risk that I accidentally end up with anything 64bit).
I also found that you need to install a special Visual Studio for Python instance as described here:
Microsoft Visual C++ Compiler for Python 3.4
If you are using Python 2.7 this VSC version should do the trick for you, only newer version (3.5, 3.6) are left out at this time.
For reference here is my complete f2py invocation on the console that I ended up using (neither python nor f2py were on the execution PATH):
python C:\Python34\Scripts\f2py.py -c cuncsd.pyf --opt="-frecursive -fmax-stack-var-size=66560" cuncsd.f -llapack -lrefblas -ltmglib
This particular module depends on 32 bit LAPCK shared libraries that I compiled previously, and we found it even works on XP systems.
I later went back and tried to compile this for 64 bit, but eventually gave up, when I always encountered ld errors. I think going forward for Windows 10 it will be much easier to use the embedded Ubuntu to execute and extend Python.
(See How to enable Bash in Windows 10 developer preview? and Getting PyCharm to recognize python on the windows linux subsystem (bash on windows))
I have installed SimpleCV 1.3 powerpack in my Windows 8.1. Then i set up the required path. And then i installed pyreadline, PIL, pip, ipython via cmd. But when i tried to run easy_install cython, i'm getting the following error,

Please help me out.
I'm using a double partition system Windows8/Xubuntu14.04LTS.
I had the same issue when attempting to install Cython onto Xubuntu via pip.
So I installed Cython with below command and and everything went ok.
bashsh $ sudo apt-get install cython
This is not the best fix. But, may worth a trial if you are really
looking to port an almost complete project to Windows8.
You compile your Python main (without main):
bash $ cython --embed -o prog.c prog.py
You may decide to install Mxe (MingW) gcc on linux and do
cross compiling or, as me, to compile directly in the windows8:
bash $ gcc -Os -IC:\Python27\include -LC:\Python27\libs -o prog.exe prog.c -lpython27 -DMS_WIN64
Hope this might be of any help.
Recently, I downloaded and installed Fedora Scientific 20 as I was
impressed with the list of included software. My interest in the software
is due to the inclusion of the MPI framework. I was able to compile and
execute a simple C program using mpicc and mpiexec. However, I need some
help using MPI4PY to call OpenMPI using Python code.
At the terminal prompt, if I try:
$ /lib64/openmpi/bin/mpiexec -n 2 python3 helloworld.py
The Traceback reports that an
ImportError: No module named 'mpi4py'
has been raised. The helloworld.py program was an example found online with
line 6 being from mpi4py import MPI.
Since Apper indicates that mpi4py has been installed for both Python2 and
Python3 for OpenMPI as part of the installation of Fedora Scientific, I'm not sure what might be wrong. Could somebody please advise as to how to use this package?
It sounds like there is something wrong with your environment. Perhaps mpi4py, since you have confirmed it is installed, is installed in a a strange place. Would setting PYTHONPATH help?
