I have a python file running perfectly in the IDE.
I want to run it on a different PC without any IDE.
I run the program from the command line: python program.py
Error message: File "program.py", line 8, in
from mpl_finance import candlestick_ohlc
ModuleNotFoundError: No module named 'mpl_finance'
When trying: pip install mpl_finance (or pip install mpl_toolkits)
I get the message: No matching distribution found for mpl_finance (or mpl_toolkits)
There also seems to be a problem with matplotlib backend.
Looking for a solution please.
After many failed paths, here's what worked:
matplotlib.finance is deprecated and it is now mpl_finance.
Create 2 files named mpl_finance.py and setup.py and get their contents from here.
Then from the command-line: python setup.py install
Fixing the backend (this can save you a few days):
If the backend of matplotlib was set in a file original PC (and not in the code). Then you need to do the same on the second PC.
Windows Path: C:\Program Files\Python36\Lib\site-packages\matplotlib\mpl-data\matplotlibrc
Change (probably line 38) to this: backend : Qt5Agg

or using in Blender i got:

I am not a python lib installing pro...so obviously i made something wrong. But how do i fix that?
Maybe i have to say i am working on a M1 Macbook
looks like you may need to repoint your pycharm to your installed python interpreter.
go to command line and find out python interpreter path. On windows you can where python in your command line an it will give you where your python and packages are installed.. You could also activate python directly in command line and find paths from there. For example, open command line then;
python
press enter = activates python
within then you can do:
import sys
for x in sys.path: x
In pycharm make sure you point to path discovered from step 1 and select that to be your python interpreter within pycharm --- check out examples here https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#add-existing-interpreter
Should work. Not sure about all the steps you took, but if you installed python with pycharm on top of your regular installation of python i would recommend :
finding all the paths from step 1
deleting python using system
checking if folders found from paths step still exist
if they do, delete those as well
start over just with one python installation
repoint to that in pycharm
first
pip uninstall PIL
after uninstall
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
or
brew install Pillow
I want to install labelImg for mac OS in python 3.7. here is the repo: https://github.com/tzutalin/labelImg
I have installed previous modules via 'pip3 install pyqt5 lxml' successfully. Cloned the repo, entered the folder 'labelImg', but only 'make qt5py3' does not work..
but when I execute 'make qt5py3', i get the error
pyrcc5 -o libs/resources.py resources.qrc
make: pyrcc5: No such file or directory
make: *** [qt5py3] Error 1
What can I do here? What might have caused the issue?
-find 'pyrcc5' under python bin, and copy 'path'
-under labelImg find 'Makefile' and edit
-change line
qt5py3: pyrcc5 to qt5py3: 'copied path'/pyrcc5
and save
-and
make qt5py3
python labelImg.py
should works.
I had the same issues as the OP, but with Python 3.6.11. In addition, I got ModuleNotFoundErrors for pyqt5 and libxml2, even though brew confirmed they were both installed. Also, I was trying to install in a virtual environment set up using pyenv.
What finally worked for me was:
1) use global env, not virtual
2) use pip (not pip3) to install pyqt5 and lxml
3) change the makefile as #zippo suggested
After I did that, I was able to get labelImg to start by running:
python labelImg.py
I have seen many more or less related questions on this topic, but none helped me finding a way to solve my problem.
I'm not very familiar with Windows environment, deep apologies if my question sounds obvious to some extent.
Setup:
Windows 10
Python 3.7.0 (installed through latest Anaconda release)
Spyder 3.3.1
Im running a Python, that involves several modules import. I came across some module issues. For example:
from PIL import Image as PIL_Image
Works smooth in Spyder, but gives (error message in french but I guess you got the point):
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\my_user_name\Anaconda3\lib\site-packages\PIL\Image.py", line 64, in <module>
from . import _imaging as core
ImportError: DLL load failed: Le module spécifié est introuvable.
If executed in Powershell or cmd.
What I tried:
Appending Anaconda's install path to my path variable before I open Powershell:
$Env:path += ";C:\Users\my_user_name\Anaconda3;C:\Users\my_user_name\Anaconda3\Scripts"
Checking that sys.path is the same in Powershell and Spyder. For both, it looks like:
['',
'C:\\Users\\my_user_name',
'C:\\Users\\my_user_name\\Anaconda3\\python37.zip',
'C:\\Users\\my_user_name\\Anaconda3\\DLLs',
'C:\\Users\\my_user_name\\Anaconda3\\lib',
'C:\\Users\\my_user_name\\Anaconda3',
'C:\\Users\\my_user_name\\AppData\\Roaming\\Python\\Python37\\site-packages',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages\\win32',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages\\win32\\lib',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages\\Pythonwin',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages\\IPython\\extensions',
'C:\\Users\\my_user_name\\.ipython']
What else could explain that my import fails outside of Spyder ?
Ok I could not find a clean way out, so let me just share my experience in case someone finds it helpful ...
The DLL failure with PIL related libs seems to be a known issue. See further explanations:
https://github.com/python-pillow/Pillow/issues/2945
PIL: DLL load failed: specified procedure could not be found
How I solved my issue:
Cleanly uninstalled anything related to Python on my laptop. Both Anaconda, isolated Python installs, Spyder ...
Re-installed the latest Anaconda. It happens to come with Python 3.7.1 instead of 3.7.0
Re-did my PIP installs of everything. Note I had to append Anaconda\Library\bin to my Windows path for PIP to work completely, which I don't recall having done with my previous installation.
Environment info: Anaconda, windows7x64, py3.5
I setup a virtual env named as menpo to run menpoproject. For a long time I was using load_dlib_frontal_face_detector smoothly. After tinkering with a pip-install dlib command accidentally on virtualenv (I mean via Anaconda Prompt menpo) , I couldn't get my code working due to an "ImportError" ImportError: cannot import name' load_dlib_frontal_face_detector'. Code is like below:
import cv2
import menpo.io as mio
import menpodetect
Throws error at line 3.
There is this guy seems to had a similar issue.
https://github.com/menpo/menpodetect/issues/15
I did all the
conda remove dlib -y
pip uninstall dlib
conda install -c conda-forge dlib
stuff but still got the same error. Besides that;
Uninstalled Anaconda completely
Removed all Python folders wherever I found.
Installed Anaconda and setup a new menpo virtual env and still no luck. It seems like this dlib installation I made causing some issues. BTW, conda list produces dlib 18.18 py35_2 menpo and there is no pip line as mentioned in the link given above.
Wrong alarm. Seems that I've named my py file as menpodetect which I shouldn't do. Problem solved.
I am trying to run server for iphone using http://www.raywenderlich.com/3932/how-to-create-a-socket-based-iphone-app-and-server
My machine is mac 10.6.8
Python version : 2.7.3
I dont have any knowledge regarding python.
i have installed Twisted-12.1.0 additionally but still i am getting this error.
Traceback (most recent call last):
File "chatserver.py", line 1, in
from twisted.internet.protocol import Protocol, Factory
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/twisted/internet/protocol.py", line 15, in
from zope.interface import implements
ImportError: No module named zope.interface
later i have downloaded zope.app.wsgi-3.15.0 4 but i dont know how to use it.
The problem is that an __init__.py file is not present under zope directory so this directory is not scanned for imports.
Creating a blank __init__.py file under zope directory will do the trick.
I solved this error in UNIX by browsing to the zope directory by executing:
$touch __init__.py
I can confirm that this works also with virtualenv pip installation of zope interface
Here's a solution
It says that installing a zope module through pip breaks your zope installation because pip installs it in another directory other than the original zope module directory.
From the link
After install a zope module using pip, for example z3c.password your
zope installation gets broken.
This is because pip have installed the module in
/usr/local/lib/python2.6/dist-packages/zope and the original module
zope.interface is in /usr/share/pyshared/zope/interface/ and has minor
relevance when importing.
What worked for me is (also given in the link):
cd /usr/local/lib/python2.7/dist-packages/zope
sudo ln -s /usr/share/pyshared/zope/interface/
Off the top of my head you can use easy_install for this.
You will need the python-setuptools then you should be able to use
easy_install zope.interface
If I remember correctly however twisted should be installed as part of OS X python install. Do a quick Google for installing zope.interface for Mac OS X. As twisted is such a widely used library there is plenty of information out there.
