I'm very new to python and trying one of my first projects. I have installed modules 'pandas' and 'alpha_vantage' and imported them at the top of my code but they show the errors 'reportMissingModuleSource' for pandas and 'reportMissingImports' for alpha_vantage. I installed them in Command prompt and it was successful but it seems python doesn't recognise them or cant find them.
Potentially useful info:
When I first installed python I had to go into my Path settings and create a new Path to python.
I use VSCode
I had issues installing pip I cant remember why because I've been at this for hours.
Python version is 3.10.5 64bit
Pip version is 22.1.2
I am on Windows
I don't know what python files need to go where so they are slightly scattered around my directory.
Do I need to create a Path in my settings to each module, I already have one going to my scripts folder. I am very stuck so any help is appreciated.
Thank you for anyone that helps!
I have a GUI application made using PySide2 and it some major modules it uses are OpenVino(2019), dlib, OpenCV-contrib(4.2.x) and Postgres(psycopg2) and I am trying to freeze the application using PyInstaller (--debug is True).
The program gets frozen without errors but during execution, I get the following error:
Fatal Python error: initfsencoding: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'
after which the application exits.
I have tried many suggestions provided in other stackoverflow questions/github issues but none of them have worked.
I have python version 3.7.6 but I have also tried with 3.6.8 (both local installation and after creating new venv in pycharm). I have tried different versions of pycharm as well(it shows som other errors below 3.5). I have tried pycharm 3.6 both develop branch and master branch.
I have checked my PYTHONPATH and PYTHONHOME in env variables, they are pointing to python's location.
I have modified my specfile to include the necessary binaries, files, imports and folders. I would share it if needed. Also any other logs during build or execution.
I would like to know what I should do to solve this, wheather this issue is because of some component or is this a PyInstaller issue, and if so, should I raise it on github.
My os is windows 10.
You changed the python version. So, you have to give a new path according to the Python version.
Just remove all older version and the current one and reinstall new Python v.3.8.1
You need to include base_library.zip in your application folder
I am working on windows 10 with PG 9.4.1 and Python 3.6
When I run the following query, CREATE LANGUAGE plpython3u; I am getting the error mentioned in the title which is could not load library "C:/Program Files/PostgreSQL/9.4/lib/plpython3.dll": The specified module could not be found.
I used dependency walker and like in this post Installing plpythonu on Windows, it was looking for python33.dll actually.Have tried to rename the file to python33.dll but that doesn't seem to work.
I have also done pip install pg
I am not sure about installing python 3.4 because my guess is that if anything works with Python 3.4, should also work with 3.6
I tried it in other people machines also and got the same response there too. Tried reinstalling PG also, but nothing seems to work.
My main work here is to run a PG function which would be calling an AWS Lambda function. Any help would be greatly appreciated.
EDIT: I have "C:\Program Files\PostgreSQL\9.4\lib\" added to PATH system variable also.
I am using python 3.5 and I am doing Algorithms specialization courses on Coursera. Professor teaching this course posted a program which can help us to know the time and memory associated with running a program. It has import resource command at the top. I tried to run this program along with the programs I have written in python and every time I received ImportError: No module named 'resource'
I used the same code in ubuntu and have no errors at all.
I followed suggestions in stackoverflow answers and I have tried adding PYTHONPATH PYTHONHOME and edited the PATH environment variable.
I have no idea of what else I can do here.
Is there any file that I can download and install it in the Lib or site-packages folder of my python installation ?
resource is a Unix specific package as seen in https://docs.python.org/2/library/resource.html which is why it worked for you in Ubuntu, but raised an error when trying to use it in Windows.
I ran into similar error in window 10. Here is what solved it for me.
Downgrade to the Apache Spark 2.3.2 prebuild version
Install (or downgrade) jdk to version 1.8.0
My installed jdk was 1.9.0, which doesn't seem to be compatiable with spark 2.3.2 or 2.4.0
make sure that when you run java -version in cmd (command prompt), it show java version 8. If you are seeing version 9, you will need to change your system ENV PATH to ensure it points to java version 8.
Check this link to get help on changing the PATH if you have multiple java version installed.
Hope this helps someone, I was stuck on this issue for almost a week before finally finding a solution.
When I write import MySQLdb in Eclipse using the PyDev plugin, I get an unresolved import. However, the program runs without error. I can add an annotation to get the error to go away, but what is the right way to handle this?
How can I help Eclipse know that MySQLdb is there?
It sounds like MySQLdb is somewhere on your sys.path, but not on your Eclipse project's PYTHONPATH; in other words, Eclipse thinks you're going to get an import error at runtime because you haven't fully configured it. Google seems to say that you can alter this setting in Window->Preferences->Preferences->PyDev->Python Interpreter to include the path to your MySQLdb module.
For some help figuring out where MySQLdb might be living on your system:
Open an interactive interpreter,
import MySQLdb
If that succeeds, you can get a hint from: print MySQLdb.__file__; it may be the __init__ file in the package that you need to point the path at.
cdleary above provided the reason two years ago, but this may be easier. Basically, one reinstalls the interpreter.
Select Window - > Preferences -> PyDev -> Interpreter - Python
Select the python interpreter in the upper pane
Click on Remove
Click on Auto Config
Agree to everything.
This works on Fedora 17 using the Eclipse 4.2.0 that came with the package management.
Fixed this by doing two things:
1) Added MySQLdb egg to the PYTHONPATH under Window->Preferences->Preferences->PyDev->Python Interpreter.
C:\Python26\Lib\site-packages\MySQL_python-1.2.3c1-py2.6-win32.egg
2) Close and re-open the .py file that had the red x.
Adding the egg works, but the error remains. The solution for that error can be found by adding
##UnresolvedImport
To the import statement, as in:
import web ##UnresolvedImport
Source: http://klaith.wordpress.com/2009/06/12/pydev-unresolved-import-errors/
I once had a similar problem on Windows (never encountered this on Linux though) and I discovered that I had to include the .egg directory of my library to my PYTHONPATH.
For example my PYTHONPATH (Pydev/Interpreter - Python/Libraries) included:
C:\Python26\Lib\site-packages
and I had to add:
C:\Python26\Lib\site-packages\jinja2-2.2.1-py2.6.egg
to use jinja.
This surely works I just tried it with Pmw package. Unzip package in site-packages. Then remove python interpreter from eclipse and then add it again. Your import errors shall go away. also you may want add module to forced builtins. See How do I fix PyDev "Undefined variable from import" errors? and http://pydev.org/manual_101_interpreter.html
I had a similar issue and the following is what I did to solve my issue. I have a Windows 8 Machine, Python 2.7 installed and running my stuff through eclipse.
Some Background:
When I did an easy install it tries to install MySQL-python 1.2.5 which failed with an error: Unable to find vcvarsall.bat. I did an easy_install of pip and tried the pip install which also failed with a similar error. They both reference vcvarsall.bat which is something to do with visual studio, since I don't have visual studio on my machine, it left me looking for a different solution, which I share below.
The Solution:
Reinstall python 2.7.8 from 2.7.8 from https://www.python.org/download this will add any missing registry settings, which is required by the next install.
Install 1.2.4 from http://pypi.python.org/pypi/MySQL-python/1.2.4
After I did both of those installs, I reopened eclipse and got a prompt to update the paths of eclipse which I accepted, after that I was able to query my MySQL db.
import MySQLdb
If this code show error like this:
Unresolved import: MySQLdb
you should add D:\Python27\Lib\site-packages\MySQLdb to your sys.path.
D:\Python27\Lib\site-packages\MySQLdb is this location where you install MySQLdb in your computer disk. After this step, the error will disappear.
