So I have the infamous ModuleNotFoundError, and for a couple of hours I can't find the solution. I know that my project works in Pycharm but I wanted to set it up in Visual Studio Code.
the error

First I had __Init__.py in every dir, but then I read here http://python-notes.curiousefficiency.org/en/latest/python_concepts/import_traps.html that this also could be an issue.
I will be alert for any suggestions and will try them as I read them.
Thanks in advance :-)
You first have to add __init__.py to your MarkovDecisionProcess to make it a module. Then, you have to add \path\to\project to PYTHONPATH for you to import.
For example, in Windows:
setx PYTHONPATH /M "\path\to\project"
In Unix/macOS:
PYTHONPATH=$PYTHONPATH:/path/to/project
Then, you can import like this: from be.kdg.MarkovDecisionProcess import Agent
Alternatively, you can use importlib.util
if you want to import Agent in Main.py just use
import Agent
because which is in the same directory

I'm trying test pylucene library. I have written this code only for import test. It doesn't work. I get

I have run python3.10 -m pip list and there is "lucene" module. if I import lucene work well but python doesn't recognize org module. Why?
UPDATE
I downloaded lucene 9.1 and set environment variable (/etc/environment):
CLASSPATH=".:/usr/lib/jvm/temurin-17-jdk-amd64/lib:/home/bigissue/all_lucene/lucene-9.4.1/modules:/home/bigissue/all_lucene/lucene-9.1.0/modules" export CLASSPATH
I downloaded pylucene-9.1.0 and I have installed it
first jcc
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$ pwd
/home/bigissue/all_lucene/pylucene-9.1.0/jcc
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$python3.10 setup.py build
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$python3.10 setup.py install
I downloaded also ant apache.
then pylucene 9.1
cd ..
I have edit Makefile
vim /home/bigissue/all_lucene/pylucene-9.1.0/Makefile
PREFIX_PYTHON=/usr/bin
ANT=/home/bigissue/all_lucene/apache-ant-1.10.12
PYTHON=$(PREFIX_PYTHON)/python3.10
JCC=$(PYTHON) -m jcc --shared

bigissue#vmi995554:~/all_lucene/pylucene-9.1.0: make
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0: make install
if I run python3.10 -m pip install | grep -i "lucene" I see it.
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$ python3.10 -m pip list | grep -i "lucene"
lucene 9.1.0
Now I have imported lucene
import sys
from os import path, listdir
from lucene import *
directory = RAMDirectory()
But I get
ImportError: cannot import name 'RAMDirectory' from 'lucene' (/usr/local/lib/python3.10/dist-packages/lucene-9.1.0-py3.10-linux-x86_64.egg/lucene/__init__.py)
Python doesn't use that kind of imports.
Just import lucene.
If this doesn't fix your problem, sorry!
You can use from lucene import whatever.
See the Features documentation, where it states:
"The PyLucene API exposes all Java Lucene classes in a flat namespace in the PyLucene module."
So, in Java you use import org.apache.lucene.index.IndexReader; but in PyLucene you use from lucene import IndexReader.
Update
Regarding the latest error you mentioned in the comments to your question:
ImportError: cannot import name 'RAMDirectory' from 'lucene'
Lucene's RAMDirectory has been deprecated for a long time - and was finally removed from version 9.0 of Lucene.
You can use a different directory implementation.
Recommended: MMapDirectory - but there are other options such as ByteBuffersDirectory
(Just to note, a new error/issue should really be addressed by asking a new question.)
Im having trouble importing a python file that is in the seme directory but on a folder: ./subproject1/subproject1.py
Error:
File "/home/ubuntu4/Downloads/ProjectX/main.py", line 4, in
import subproject1.subproject1
ImportError: No module named subproject1.subproject1
The project looks like this:
/home/ubuntu4/Downloads/ProjectX
-/subproject1
- subproject1.py
main.py
And I import like this on python:
import sys
import os
import multiprocessing
import subproject1.subproject1
I have runned this from my windows PC and it works perfectly and from my ubuntu pc it isn't working, some suggestions?
I think it's a bug since I restarted the computer, without any changes and the problem was solved, when working with a virtual environment in a virtual machine it may have generated a bug
I am in need of some help with the below. Using Python 3 code on Windows 10. Written in Spyder over Anaconda install and custom environment.
I have some code that runs in Spyder but not Anaconda Prompt. It gets a ModuleNotFoundError. The directory/file structure is like this:
my_python
smb_bau
etl
init.py
etl_globals.py
init.py
my_config.conf
my_connections.py
my_definitions.py
init.py
(underscores round init not displaying for some reason)
Some notes before the problematic code:
It's just test code for now that will be replaced with the real hive code later.
The code works when all the files are in one foler.
Th my_ prefixes are just to avoid any word that might cause issues while testing.
In my_connections I have this code:
class hive_connection:
def __init__(self):
self.my_name = None
self.my_town = None
import configparser
from smb_bau.my_definitions import CONFIG_PATH
config = configparser.ConfigParser()
config.read(CONFIG_PATH)
my_details = config["my_details"]
self.my_name = my_details["my_name"]
self.my_town = my_details["my_town"]
And this is what's in my_definitions:
import os
ROOT_DIR = os.path.dirname(os.path.abspath(__file__))
CONFIG_PATH = os.path.join(ROOT_DIR, 'my_config.conf')
(I gratefully stole this from another thread to solve the issue of getting config info from a different folder).
The file I run is etl_globals which contains this code:
from smb_bau.my_connections import hive_connection
hive = hive_connection()
print(hive.my_name, hive.my_town)
When I run etl_globals in Spyder it works perfectly. But it fails in Anaconda Prompt.
I open up Anaconda Prompt, activate my environment, navigate to the etl folder, and enter python etl_globals.py
The error message I get is:
Traceback (most recent call last):
File "etl_globals.py", line 1, in
from smb_bau.my_connections import hive_connection
ModuleNotFoundError: No module named 'smb_bau'
I don't understand why the import of modules works in Spyder but not Anaconda Prompt.
The overarching goal is to be able to not have all the files in one folder.
Any help would be gratefully appreciated.
Many thanks.
Edit:
Just to be sure what the issue is I simplified it to create a file called my_functions (in the smb_bau folder) with this in:
def fn_test():
print(5)
And a file in the etl folder called my_test with this in:
from smb_bau.my_functions import fn_test
fn_test()
And got the same error:
Traceback (most recent call last):
File "my_test.py", line 1, in
from smb_bau.my_functions import fn_test
ModuleNotFoundError: No module named 'smb_bau'
Why does from smb_bau.my_functions import xxx work in Spyder but not Anaconda prompt?
Also, this may be relevant: the only reason there is a folder called my_python at the top is that I was getting an error saying no module named smb_bau. So I moved it all down a level and then it would accept smb_bau as a module but only in Spyder).
I also just checked PYTHONPATH and the root folder is there.
I have only been using Python for a week so I'm sure there are other bit of my code that aren't great -- but it does work in the spyder client.
Thanks and sorry if any of this is unclear.
I am following the tutorial from Microsoft ( https://learn.microsoft.com/nl-nl/azure/cognitive-services/Computer-vision/quickstarts-sdk/client-library?pivots=programming-language-python ) to use cognitive service. I use herefor Visual Code and install the Azure with pip using the commandline:
pip install azure-cognitiveservices-vision-customvision
I use the first peace of code(see code below) and try to run the code. But it returns the follwowing error:
(myvenv) PS C:\Users\erikh\OneDrive\Documenten\Git\Python Testlab> & "c:/Users/erikh/OneDrive/Documenten/Git/Python Testlab/myvenv/Scripts/python.exe" "c:/Users/erikh/OneDrive/Documenten/Git/Python Testlab/readText.py"

And here is the code which i try to execute:

if 'COMPUTER_VISION_SUBSCRIPTION_KEY' in os.environ:
subscription_key = os.environ['COMPUTER_VISION_SUBSCRIPTION_KEY']
else:
print("\nSet the COMPUTER_VISION_SUBSCRIPTION_KEY environment variable.\n**Restart your shell or IDE for changes to take effect.**")
sys.exit()
# Add your Computer Vision endpoint to your environment variables.
if 'COMPUTER_VISION_ENDPOINT' in os.environ:
endpoint = os.environ['COMPUTER_VISION_ENDPOINT']
else:
print("\nSet the COMPUTER_VISION_ENDPOINT environment variable.\n**Restart your shell or IDE for changes to take effect.**")
sys.exit()
I can reproduce your issue, you installed the wrong package, it should be azure-cognitiveservices-vision-computervision instead of azure-cognitiveservices-vision-customvision.
Run the line below, then it will work fine.
pip install azure-cognitiveservices-vision-computervision
Im trying to compile Godot engine following the instructions here
When I run scons bin/godot as the tutorial says, I get the following error:
scons: Reading SConscript files ...
ImportError: cannot import name _args_from_interpreter_flags:
File "/home/grayfox/github/godot2/godot/SConstruct", line 9:
import multiprocessing
File "/usr/lib64/python2.7/multiprocessing/__init__.py", line 65:
from multiprocessing.util import SUBDEBUG, SUBWARNING
File "/usr/lib64/python2.7/multiprocessing/util.py", line 40:
from subprocess import _args_from_interpreter_flags
The SConstruct file starts this way:
EnsureSConsVersion(0,14);
import string
import os
import os.path
import glob
import sys
import methods
import multiprocessing
...
If I try to run python SConstruct I get an error complaining about missing functions defined by scons (i.e. the script fails after doing all the imports).
Commenting import multiprocessing fixes the issue but I don't want to modify that file, as I would have to revert the change if I ever make a pull request. The project is quite active so I believe this has something to do with my local configuration.
Any ideas why the script is failing to import _args_from_interpreter_flags only if I execute it via scons?
[UPDATE]
I did a fresh Gentoo install and the problem persists. I did some tests and I found this:
In a python terminal>
>>> import SCons.Script
>>> from subprocess import _args_from_interpreter_flags
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name _args_from_interpreter_flags
>>> import subprocess
>>> subprocess.__file__
'/usr/lib64/python2.7/site-packages/SCons/compat/_scons_subprocess.pyc'
But the output is different if I do this:
>>> import subprocess
>>> subprocess.__file__
'/usr/lib64/python2.7/subprocess.pyc'
So I update my question: Is this a bug? Can anybody reproduce it in other distros? If it's a bug, should I report it to Gentoo or to SCons?
[ANOTHER UPDATE]
Adding temp.extend([os.path.join(x, 'lib64') for x in prefs]) did't work, same error.
Adding print sys.path at the beginning of the compact module gives:

It looks as if this isn't really a problem connected to SCons directly. You might have an alien "subprocess" module/package installed in your system. Also check out Cannot import name _args_from_interpreter_flags which seems to be related.
Based on your updated question: I tried to compile Godot on my machine (Python 2.7.3, SCons 2.3.1, Ubuntu 12.04 LTS) and it's running fine, so the problem is not related to the provided SConstruct (and its supporting build description files in subfolders). The "_scons_subprocess" module gets used only when the import of the original "subprocess.py" fails. So I suspect that the SCons start script sets up a wrong sys.path, which may happen under 64bit (see issue http://scons.tigris.org/issues/show_bug.cgi?id=2657 ).
After you added "temp.extend([os.path.join(x, 'lib64') for x in prefs])", your "print sys.path" statement shows paths like "/usr/lib64/python-exec" in its output. A Google search turned up the page http://forums.gentoo.org/viewtopic-t-985402-start-0.html for me. It describes an issue with Gentoo, where programs are installed as links to pip. Please follow the given advice and see if this fixes your problem.
It's a bug in Gentoo's scons-2.3.0 and scons-2.3.1 ebuilds (see bug report). It has been fixed in versions 2.3.1-r1 and higher.
