I am trying to install a python package from gitlab. I am using pip install git+gitlab_package_address, like here. After that, I am able to import the package. But the package comes with an .so file and later it throws an error: OSError: $LD_LIBRARY_PATH/lib{that_package}.so: cannot open shared object file: No such file or directory.
Manual trial: I can clone the repo via SSH and move into the repo directory. Compile to get the desired lib{that_package}.so (checked that it exists using ls) and using export LD_LIBRARY_PATH=/absolute/path/to/the/repo/directory. Still the same error.
Any help is appreciated.

I am trying to get the python package simms to work on my computing cluster. Unfortunately there isn't much documentation. I have
inside my conda env installed it via
pip install simms
I also git cloned https://github.com/ratt-ru/simms.git to
my_dir/simms
Then inside my conda env, running the suggested:
python my_dir/simms/tests/tests.py
gives an error
FileNotFoundError: [Errno 2] No such file or directory:
'casa': 'casa'
I have filled the instructions at
https://github.com/ratt-ru/simms/blob/master/tests/test.py to install the
CASA package (from https://casa.nrao.edu/installlinux.shtml) . After
uploading and unzipping, I added it to my path variable with
export PATH=$PATH: mydir/casa-6.5.2-26-py3.8
Note that casa-6.5.2-26-py3.8 has a subfolder bin/ so things Python should know where to look, but I still get the same FileNotFoundError.
When trying to install Python's sklearn package on Windows 10 using pip I am given an EnvironmentError that tells me there is no such file or directory of a specific file:
ERROR: Could not install packages due to an EnvironmentError: [Errno
2] No such file or directory:
'C:\Users\Rik\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\sklearn\datasets\tests\data\openml\292\api-v1-json-data-list-data_name-australian-limit-2-data_version-1-status-deactivated.json.gz'
I have tried reinstalling the following packages numerous times:
scikit-learn
scipy
sklearn
I have also tried downloading the github master folder for sklearn and pasting it into the directory where the installer expects the file to be, and even then when installing with pip it tells me the file is missing.
Furthermore I tried installing it via the github repository by downloading it and running
python setup.py install
But this results in weird Microsoft Visual Studio errors because apparently it is trying to run a test program or something, not sure.
Any suggestions to fix this problem?
You can find the solution here: https://scikit-learn.org/stable/install.html
The problem occurs because the default path size limit is reached in your case, you can change this with the following steps:
open regedit tool (using windows cmd)
access the 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem' key
change the 'LongPathsEnabled' value to 1
reinstall sklearn using the command 'pip install --exists-action=i scikit-learn'
I am trying to install PyHook using PIP. When I run the command on cmd pip install pyhook3 I get a C1080 error that tells me there is no such .h file located in my directory. I traced the directory, downloaded the file and it showed me another. I kept doing this until I noticed that there seems to be no end. There seems to be a lot of missing .h files in this includes folder C:\Users\User\AppData\Local\Programs\Python\Python38-32\include directory. I don't want to have to download or copy and paste source code for each of these files. Is there any way to get all of them at once, or am I missing the plot entirely?
pyhook is a Python package with binary dependencies.
When running pip install pyhook3 you download the source and ask your computer to build it so it can be installed. It thus requires a compiler and a set of header files that are apparently missing for you.
A workaround may be to download manually a compiled version of this package and install it.
You can find on this page a set of binary wheel for pyhook (not pyhook3) for python3 (32 or 64 bit). Once you have downloaded the correct .whl, you can install it with pip install the_filename_you_have_downloaded.whl
I have a problem when I'm trying to use OpenCV (v3.1.0) in Python (v3.4). To make things more complicated, OpenCV is built with the "contrib" package and Qt support (v5.5).
This is what I did (this has some pitfalls on it's own, but those are out of the scope of this question):
Install required software
I installed WinPython (v3.4.4, 64 Bit version)
I installed cmake (v3.6.0)
Download sources
I downloaded the Qt sources from the GIT repo
I downloaded the OpenCV sources from the GIT repo
I downloaded the OpenCV "contrib" sources from the GIT repo
build sources -> RELEASE, 64 Bit (!)
build Qt from sources
build OpenCV from sources (with "contrib" modules)
cmake ( OpenCV 3.1.0 for python 3 ) already took care of copying the "cv2.pyd" to the "your/python/folder/Lib/site-modules" directory.
Now I have the problem that calling "import cv2" from python gives the error "
>>> import cv2
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import cv2
ImportError: DLL load failed: Module not found
How can I find out which module is missing and how to solve it?
What you may not want to do is just adding paths that are likely needed to your environment variables.
There is a way to find out what is missing:
Download DependencyWalker
open your "cv2.pyd" with the dependency walker
Analyze your file (starts automatically when you select your file)
Hit "F9" such that it shows the full paths to the required DLLs
Check, which DLL files are missing
Copy them to those folders
For me, it was the case that python/cv2.pyd searched to all the Qt DLLs in the folder where cv2.pyd is in.
I just copied them there and that was it.
For Windows:
Step 1. Download python installer from https://www.python.org/downloads/
,install python by double clicking this file and check the option for adding python to PATH as in given image.
Step 2. Download file "numpy‑1.15.4+mkl‑cp27‑cp27m‑win32.whl" from unofficial site.
Go to this file's location open command prompt and type-
pip install numpy‑1.15.4+mkl‑cp27‑cp27m‑win32.whl
Now go to python IDLE and type:
import numpy
It should give no error.
Step 3. Download file "scipy‑1.2.1‑cp27‑cp27m‑win32.whl" from unofficial site.
Go to this file's location open command prompt and type-
pip install scipy‑1.2.1‑cp27‑cp27m‑win32.whl
Now go to python IDLE and type:
import scipy
It should give no error.
step 4 : Download file "opencv_python‑2.4.13.7‑cp27‑cp27m‑win32.whl" from unofficial site.
Go to this file's location open command prompt and type-
pip install opencv_python‑2.4.13.7‑cp27‑cp27m‑win32.whl
Now go to python IDLE and type:
import cv2
It should give no error, means opencv installed successfully in windows.
I am trying to export a GeoTiff with Blender using the Blender Python API (based on Python 3), so I've decided to install GDAL on Ubuntu (14.04). What I would like is to get the module as a standalone folder that I could put in the modules directory of Blender (/home/user/.config/blender/2.73/scripts/modules).
The thing is I've run through several different problems trying to install GDAL. I've tried to install from source (for GDAL 2.0.0) here : Official PyPi Gdal
I ran sudo apt-get install libgdal-dev gdal-bin (I list it here because it may be important)
When I am in the extracted GDAL folder, using python setup.py build & python setup.py install, the library installs to /usr/local/lib/python2.7/dist-packages/osgeo. However, when I run python from command line, running from osgeo import osr returns ImportError: No module named _gdal
Following GDAL via pip , I used pip (pip install GDAL) to install the library, and the folder it went to was /usr/lib/python3/dist-packages/osgeo (using pip show ...). Again, running python3 and trying to import results in the same error. Of course, when I copy-paste each folder in the blender module directory, I get the same error in the Blender Python console.
So I decided to compile the sources using ./configure --with-python & make & make install in the source folder. I then copied the folder GDAL-x.x.x/build/lib.linux-x86_64-3.4/osgeo to the blender modules directory and got this time the error when importing : ImportError: /home/yvesu/.config/blender/2.73/scripts/modules/osgeo/_gdal.so: undefined symbol: _Py_ZeroStruct.
Trying to compile with python3 using python3 setup.py build returns the error error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
EDIT 1:
I think I've found the solution : I went to the directory swig/python (not found in a GDAL-1.11.0 folder but gdal-1.11.0 fodler, can't remember where I downloaded it from), ran python3 setup.py build & python3 setup.py install and could finally find the folder in /usr/local/lib/python3.4/dist-packages/GDAL-1.11.0-py3.4-linux-x86_64.egg/osgeo. When I put this osgeo folder oni the Blender modules directory, I was able to import osgeo in Blender. I will report if anything went wrong.
I think I've listed all my attempts at installing GDAL on Ubuntu. Can anyone point me in the right direction? Do you think it is even possible to install it as a standalone module, or do I need linked libraries through LD_LIBRARY_PATH?
Here is the solution I've found :
Download Gdal sources (v2.0.0 is the current stable release) from ftp://ftp.remotesensing.org/gdal/2.0.0/ or http://download.osgeo.org/gdal/2.0.0/ and untar
Go to the directory gdal2.0.0/swig/python
Run python3 setup.py build & python3 setup.py install
Finally find the module folder in, on Ubuntu : /usr/local/lib/python3.4/dist-packages/GDAL-2.0.0-py3.4-linux-x86_64.egg/osgeo
I can now use it in Blender (copying in the modules directory)
