I've created a python tool and want to install it via brew. Creating the formula worked fine at first when i simply had one python file named myTool. Then i seperated the code into more files as it became larger and more complex.
How do i set up the install to bundle those files, because right now the imports are failing because the other files are not found.
My current install
def install
bin.install 'myTool'
end
The error shown when running the brew installed tool
from myModule import someFunc, someOtherFunc ModuleNotFoundError: No module named 'myModule'
The current setup only installs the angler file without any of the other python modules. This results in the ModuleNotFoundError error. Here is my suggestion:
def install
# Determines the python version being used
# e.g. If python3.10, xy = 3.10
xy = Language::Python.major_minor_version "python3"
# Where to install the python files
packages = libexec/"lib/python#{xy}/site-packages/angler"
# For each file present, install them in the right location
%w[angler anglerEnums.py anglerGen.py anglerHelperFunctions.py].each do |file|
packages.install file
end
# Create a symlink to the angler python file
bin.install_symlink packages/"angler"
end

Following this source I would like to install METIS and the Python wrapper in colab:
https://github.com/james77777778/metis_python
The installation steps are listed as the following:
Download and extract metis-5.1.0.tar.gz from METIS - Serial Graph Partitioning and Fill-reducing Matrix Ordering
cd metis-5.1.0
make config shared=1 prefix=~/.local/
make install
export METIS_DLL=~/.local/lib/libmetis.so
pip3 install metis-python
However, I'm not sure how to do steps 2-4 in colab specifically and so I get the following error:
RuntimeError: Could not locate METIS dll. Please set the METIS_DLL environment variable to its full path.
Thanks!
The issue seems to be the location of the libmetis.so file. Copying the file to /usr/lib and updating the path for the environmental variable successfully completes the process:
import requests
import tarfile
# Download and extract the file
url = "http://glaros.dtc.umn.edu/gkhome/fetch/sw/metis/metis-5.1.0.tar.gz"
response = requests.get(url, stream=True)
file = tarfile.open(fileobj=response.raw, mode="r|gz")
file.extractall(path=".")
# Change working directory
%cd metis-5.1.0
# The remaining steps as you have shown in the question, with updated path
!make config shared=1 prefix=~/.local/
!make install
!cp ~/.local/lib/libmetis.so /usr/lib/libmetis.so
!export METIS_DLL=/usr/lib/libmetis.so
!pip3 install metis-python
import metispy as metis
I want to install PyMesh on a Windows 10 PC, if possible it should be installed in the side-packages of an interpreter delivered with the IDE we use.
I tried the way to run the setup discribed here
https://pymesh.readthedocs.io/en/latest/installation.html
so the part :
git clone https://github.com/PyMesh/PyMesh.git
cd PyMesh
git submodule update --init
worked without any problems.
I am not sure on windows if I now just can write
set PYMESH_PATH = path
and if i can use the path "...\PyMesh\PyMesh" here?
so i left out this part
I installed numpy and scipy (allready installed)
and nose because it is mentioned in the requirements.txt.
So my numpy scipy and nose versions are
numpy 1.19.1
scipy 1.6.0
nose 1.3.7 (same as requirenments)
and just run the setup.py with admin rights
python .\setup.py install
which also seemed to work but i got an error trying
python -c "import pymesh; pymesh.test()"
from the PyMesh folder
saying ModuleNotFoundError: No module named 'PyMesh'
or if i go up one Folder doing the same
saying AttributeError: module 'PyMesh' has no attribute 'triangle'
I found this link ImportError: No module named PyMesh
but i just dont know what i should type in there
I tried to install via pip by using pip install pymesh
but pip Installer gives me a different library.
So i tried in the docker version and in docker i tried the pymesh.load_mesh method with an stl File
but got
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
I dont know if this is just the stl format (expecting binary getting ascii or vice versa)
The stl file itself can be opened so shouldnt be corrupted.
So is there a different way to install pymesh? A wheel would be great. Is it possible to install pymesh to the side-packages of a given Interpreter? Did someone else allready had the same error in Docker and knows the issue
thank you for your help
I've installed this package via pip27 on macports. My OS is OSX El Capitan 10.11.6. My python install is 2.7.10.
I'm trying to run an example script that imports googlemaps module, but I keep getting that ImportError. I have a feeling that it's how pip installed it and the reason why python can't find it, but I'm relatively new to pip so I don't know where to start investigating.
I also tried googling for a fix but no dice. Any idea what's happening here?
Here's my code:
import googlemaps # can't import
import argparse
from datetime import datetime
# collect args for lat, long, # of addresses, radius of search
parser = argparse.ArgumentParser(description='Randomize addresses on Google Maps')
parser.add_argument('-lt', '--latitude')
parser.add_argument('-lng', '--longitude')
parser.add_argument('-n', '--count')
parser.add_argument('-r', '--radius')
args = parser.parse_args()
print('Results: ', vars(args))
Error message:
Traceback (most recent call last):
File "randomize_addresses.py", line 1, in <module>
import googlemaps
ImportError: No module named googlemaps
Found a fix. I uninstalled googlemaps via pip and then reinstalled using easy_install. Apparently OSX doesn't like pip.
Looks like you used pre-installed python since you mentioned version 2.7.10 (default version shipped with macOS) which is located at /usr/bin/.
MacPorts installs binaries and libraries under /opt/local. Try to install python via MacPorts and run the program again. Python and pip should both be linked so that packages installed via pip is available to python.
In this case packages installed using pip27 would be available to python27 installed via MacPorts and not /usr/bin/python.
Another way would be to download get-pip.py and install it against /usr/bin/python (pip installation guide).
Note: Make sure you are using python installed via MacPorts. To check this run which python, it should show something like /opt/local/bin/python2.7
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
#include "Src/Python3/cxxsupport.cxx"

#include "Src/Python3/cxxextensions.c"
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
...

Compile: /code/pysvn-1.9.10/Import/pycxx-7.1.3/Src/cxx_exceptions.cxx into cxx_exceptions.o
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/
cp /code/pysvn-1.9.10/Sources/pysvn/_pysvn*.so /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!
