I am new at installing external Github packages into python.
I successfully cloned a package by running the command
git clone https://github.com/vishnubob/python-midi.git
However, when I ran
python setup.py install
I received the error:
No sequencer available for 'win32' platform.
C:\Python27\lib\site-packages\setuptools\dist.py:341: UserWarning:

writing dependency_links to midi.egg-info\dependency_links.txt
writing manifest file 'midi.egg-info\SOURCES.txt'
**error: package directory 'src' does not exist**
Is this a directory problem? And is there another approach to install this package (possible via pip)?
The readme on git hub has: "I am extremely interested in supporting OS-X and Win32 sequencers as well, but I need platform expert who can help me. Are you that person? Please contact me if you would like to help."
So it is simply not supported on Win32.

I'm trying to install/import a cython dependent module [ZigZag] into my python function on Azure functions (Linux platfrom), I'm working via Windows 8.1 (VSCode), Running Python 3.6 on both local machine and azure functions.
I tried including Cython in the requirements.txt file, this errors out during deployment (seems installation of external modules happens somewhat in parallel)
I tried creating a '.toml' file, no luck.
I also tried the idea found here Python google cloud function deployment failure - Madmom pip package still didn't work.
Finally I decided to deploy the function first (with cython included in the 'requirements.txt' file) without the zigzag module, and then in my python script use subprocess.Popen() to do a pip install zigzag and import it before the rest of the function runs.
This is where I get stuck. In my python file I have these lines included to do the above:
#function to be called in azure __init__.py file
def f....:
# check for zigzag
try:
import zigzag
except ImportError:
subprocess.Popen(["pip", "install", "ZigZag"], shell=True)
finally:
import zigzag
.
.
.
rest of the function...
This deploys successfully to azure functions, however it fails during execution with the error:
Microsoft.Azure.WebJobs.Script.Workers.Rpc.RpcException :
Result: Failure Exception: ModuleNotFoundError: No module named 'zigzag
Any idea's how to do this correctly?
NB: This issue occurs on google cloud functions as well.
I see this is related to https://learn.microsoft.com/en-us/answers/questions/152557/index.html
As per the thread, the latest version for ZigZag is 0.2.2 and the supported python version is 3.5: https://pypi.org/project/ZigZag/
The azure function supports 3.6 and above python version which will make it incompatible. You can try installing the latest cython using requirements.txt and it will work as expected. But when you try to install ZigZaG it tries to find the dependency of cython package (Cython==0.26.1) that is compatible with it therefor it throws the error that cython package not found.
I'm working on a project which was written in Python 2, and I'm upgrading it to Python 3. So far, I've just been finding minor syntax errors which are easily fixable. What I've done is created a new project in Python 3, ensured that it worked, and copies chunks of code from the old project into the new one.
Right now, I'm having trouble with pysvn. Initially, I was getting this error:
ImportError: No module named 'pysvn'
At this point, I tried using pip install pysvn, which didn't work. I got the following:
pip install pysvn
Collecting pysvn
Could not find a version that satisfies the requirement pysvn (from versions:)
No matching distribution found for pysvn
So then after a bit of research, I went to the pysvn download site and tried:
>pip install --index-url http://pysvn.tigris.org/project_downloads.html pysvn, which gave me this error:
Collecting pysvn
The repository located at pysvn.tigris.org is not a trusted or secure host and is being ignored. If this repository is available via HTTPS it is recommended to use HTTPS instead, otherwise you may silence this warning and allow it anyways with '--trusted-host pysvn.tigris.org'.
and also the same error as when I tried >pip install pysvn.
My next step was to manually download the .exe file for the version I needed, and I was able to successfully install pysvn. I have checked the site-packages directory, and pysvn is indeed there, but pip still can't tell me anything about it:
>pip show pysvn

When I do this for another installed module, selenium for example, I get the following:
pip show selenium

I was able to verify that the installation of pysvn was successful because my project now runs instead of giving me that ImportError.
So why can pip not give me information for another module in the same directory that was successfully installed?
As it turns out, because I didn't use pip install for pysvn, pip didn't know that pysvn existed. Because it wasn't available from PyPI (the Python Package Index), there was no way that pip could see it (because that's where pip goes first to find packages that it's attempting to install).
From the pip user guide:
pip supports installing from PyPI, version control, local projects, and directly from distribution files.
Since I had eventually downloaded pysvn from its own download site (which was not any of the above 4 options) and ran the .exe manually, pip simply doesn't know about it even though it's in the same directory as other packages installed by pip.
I suppose I could've also retrieved the distribution files and used pip with those, but my workaround did the trick.
My way on linux:
Get sources from here
tar -zxf pysvn-1.9.10.tar.gz
apt-get install subversion libsvn1 libsvn-dev make g++
cd pysvn-1.9.10/Source
python setup.py configure --pycxx-dir=/pysvn-1.9.10/Import/pycxx-7.1.3/
make
Here i've got errors below:
Compile: /pysvn-1.9.10/Import/pycxx-7.1.3/Src/cxxsupport.cxx into cxxsupport.o
/pysvn-1.9.10/Import/pycxx-7.1.3/Src/cxxsupport.cxx:42:10: fatal error: Src/Python3/cxxsupport.cxx: No such file or directory

It is needed to edit that files:
vi /pysvn-1.9.10/Import/pycxx-7.1.3/Src/cxxsupport.cxx
change #include "Src/Python3/cxxsupport.cxx" to
#include "Python3/cxxsupport.cxx"
and same on second file. Than make again:
make clean && make
...

Link pysvn/_pysvn_3_7.so
Then just copy it to the site-packages (change to yours directory):

cp /code/pysvn-1.9.10/Sources/pysvn/__init__.py /usr/local/lib/python3.7/site-packages/

I am using Python 2.7 through Anaconda 2.7.8 and need Kapteyn 2.2 to perform Non-linear Least Squares fitting easily (it is probably an alternative to Scipy.optimize.leastsq() for dummies like me!).
After copy-pasting this from a previous post here on Stack Overflow:
conda install -c https://conda.binstar.org/dhirschfeld pyodbc
and then running on my cmd (as I did not have pyodbc installed I think, because of which maybe the command prompt on my Windows 7 64-bit system was not responding well to python setup.py install inside the Anaconda directory where I unzipped the Kapteyn .zip file downloaded from University of Groningen website.
But, after the installing pyodbc properly and running python setup.py install, the cmd gave me an error saying error: command 'C:\Users\windows 7\Anaconda\Scripts\gcc.bat' failed with exit status 1. Later, when I tried to import kmpfit module (needed for Non-linear least square fitting with Kapteyn), here is the problem:
import kapteyn
help(kapteyn)

As you can see, there is no module named kmpfit (or even wcs) here. But according to http://www.astro.rug.nl/software/kapteyn/intro.html, these two should be there.
Kindly help. I have never imported any module before.
Thanks in advance...:-)
I just managed to get this working (on Mac OSX, so you may have to adjust this). My steps were:
$ conda install pyodbc (didn't need to go through binstar)
Download & unarchive the kapteyn package, then navigate to its directory
$ python setup.py install, which used my OS's C compiler and Anaconda's python, and installed kapteyn to my anaconda distro's site-packages, as it should.
Check that kmpfit.so is in the kapteyn folder in site-packages, showing that kmpfit installed correctly.
>> from kapteyn import kmpfit failed, ImportError: cannot import name kmpfit. I did some digging and discovered that it was still importing kapteyn from the folder that I downloaded, not from site-packages.
Delete the downloaded kapteyn folder, then try again. It worked!
I am trying to freeze a Little python program using pycrypto library in Windows. Last version of everything including cx_freeze.
After running >python setup.py build apparently everything goes nice.
But running the exe file generated reports the following error : ImportError: cannot import name _AES
The error is reported by AES.py file which is part of pycrypto lybrary.
I have copied the pycrypto structure in the same directory where setup.py is and I played with the contents of setup.py making a lot of subtle changes but I always get the same error.
Does someone know what I am missing?
I am attempting to install M2Crypto on a Windows XP platform. I have Python, easy_install and SWIG installed, but when I attempt to easy_install M2Crypto I get the following:
SWIG\_m2crypto.i(31) : Error: Unable to find 'openssl\opensslv.h'
SWIG\_m2crypto.i(45) : Error: Unable to find 'openssl\safestack.h'
SWIG\_evp.i(12) : Error: Unable to find 'openssl\opensslconf.h'
SWIG\_ec.i(7) : Error: Unable to find 'openssl\opensslconf.h'
error: Setup script exited with error: command 'swig.exe' failed with exit status 1
I have read elsewhere that people have suggested easy_install openssl-devel, but that simply tells me that there are no packages found with that name. Is the name perhaps case-sensitive (I've tried various permutations without success), or does that advice not apply to Windows?
I'm not looking for alternatives to M2Crypto. I am picking up some existing code that uses it, so I need to get my development environment to be able to run what's already written.
As jay stated in his answer you should try to build it from source. And I tried. The setup.py does not recognize the --openssl option. Looking at the output from the default setup.py I realized that the search location was c:\pkg and not c:\pkg\openssl.
The solution:
Download and install OpenSSL from Win32 OpenSSL
Copy the lib and include folders to c:\pkg
Check that swig.exe is available in your path
Run easy_install M2Crypto
Worked for me like a charm.
Had a similar problem. After downloading the source package of M2Crypto and reading the INSTALL file I found the following:
Differences when installing on Windows
--------------------------------------
Before building from source, you need to install OpenSSL's include files,
import libraries and DLLs. By default setup.py assumes that OpenSSL include
files are in ``c:\pkg\openssl\include``, and the import libraries
in ``c:\pkg\openssl\lib``. As with other platforms, you can specify a different
OpenSSL location with --openssl option to build_ext command.
