I am using repl.it and I want to use keras in repl.it environment, however when I used the following:
from keras.models import Sequential
I received the following error:
Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'keras'
I understand that I need to install keras package in repl.it but do not have any idea how can I do this. Can anyone please suggest any idea for the same.
Click on the package logo on the toolbar on the left hand side (depicted below), then a search bar appears where you can add new dependencies, e.g. Keras.

I used Pytesseract module for OCR. It seems slow process. So I followed
Pytesseract is too slow. How can I make it process images faster? .
I used code mentioned in https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/tesseract-ocr/xvTFjYCDRQU/rCEwjZL3BQAJ . But getting error
!strcmp(locale, "C"):Error:Assert failed:in file baseapi.cpp, line 201
Segmentation fault (core dumped),
Then i check some post and get reference to add in my code locale.setlocale(locale.LC_ALL, "C").
So after added this in my code I got another error
Traceback (most recent call last):
File "master_doc_test3.py", line 107, in <module>
tess = Tesseract()
File "master_doc_test3.py", line 67, in __init__
if self._lib.TessBaseAPIInit3(self._api, datapath, language):
ctypes.ArgumentError: argument 3: <class 'TypeError'>: wrong type`
Can anyone give idea about this error? OR If anyone have idea about best way to make OCR in fastest way using python.
You should try to convert to bytes every parameter you pass to ctypes lib calls:
self._lib.TessBaseAPIInit3(self._api, datapath, language)
Something like this is working for me:
self._lib.TessBaseAPIInit3(self._api, bytes(datapath, encoding='utf-8'), bytes(language, encoding='utf-8'))
I have got the clue here.
Please, take into consideration that the code you are using needs more fine tuning in other lib calls as the next ones:
tess.set_variable(bytes("tessedit_pageseg_mode", encoding='utf-8'), bytes(str(frame_piece.psm), encoding='utf-8'))
tess.set_variable(bytes("preserve_interword_spaces", encoding='utf-8'), bytes(str(1), encoding='utf-8'))
I would like to work with excell sheets (.xls likely per .ods conversion) via python while maintaining all of the sheet's original content. Unlike xlutils (http://www.python-excel.org/) the iac-protocol (http://pythonhosted.org/iac-protocol/index.html) seems to me to be more fit/elegant tool to maintain sheet's style,formulas,dropboxes etc. One of the steps to launch iac's server or interpreter (iacs/iaci) is to initialize the interface which consists among others of this command:
import iac.app.libreoffice.calc as localc
While import iac.app.libreoffice works fine
moving to calc level
import iac.app.libreoffice.calc
throws following error
import iac.app.libreoffice.calc
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python3.4/site-packages/iac/app/libreoffice/calc.py", line 11, in
from uno import getComponentContext
ImportError: cannot import name 'getComponentContext'
From what I've learned so far on this forum it might be linked to method name duplicity between two modules. This is where I am stuck. How do I learn which other module has such name of a method and how to fix it? Both iac-protocol and unotools are modules downloaded via pip3. I did not created method of such name in any script.
Thank you in advance for any advice!
Python3.4 on Scientific Linux release 7.3 (Nitrogen) LibreOffice 5.0.6.2 00(Build:2)
Some questions to narrow down the problem:
Did you start libreoffice listening on a socket first?
Did you import anything else before import iac.app.libreoffice.calc?
What happens when you start python in a terminal and enter from uno import getComponentContext?
I installed iac-protocol on Linux Mint and was able to import iac.app.libreoffice.calc and then use it. The installation process was complex, so I wouldn't be surprised if there is some problem with how your packages were installed, or possibly it does not work on RHEL-based systems. For one thing, it required me to install gnumeric.
The Calc "Hello World" code that worked for me is as follows.
libreoffice "--accept=socket,host=localhost,port=18100;urp;StarOffice.ServiceManager" --norestore --nofirststartwizard --nologo --calc &
python3
>>> import iac.app.libreoffice.calc as localc
>>> doc = localc.Interface.current_document()
>>> sheet = doc.getSheets().getByIndex(0)
>>> cell = sheet.getCellByPosition(0,0)
>>> cell.setString("Hello, World!")
One more thought: Have you considered using straight PyUNO starting from import uno instead of a wrapper library? That would avoid dependency on some of the extra libraries which may be causing the problem. Also there is better documentation for straight PyUNO.
I am running gridSearchCV in parallel with n_jobs > 1, but randomly hit the following crash in joblib:
TypeError: Cannot create a consistent method resolution
order (MRO) for bases JoblibException, Exception
Here is the complete stack trace:
Traceback (most recent call last):

TypeError: Cannot create a consistent method resolution

Any pointers on what this really is, and how I can debug this. Is this a known issue with sklearn
I had the exact same exception, exactly while using the GridSearchCV.
If you look at the exception, it is complaining about not being able to understand how exactly it should choose between two parent classes JoblibException and Exception. This is a bug in the joblib package, that the inheritance is improper.
But other than than, there exist another problem, which is the source of the exception itself. It's getting an exception while retrieve()ing, and while passing the exception, you get the error.
The second problem (which is the source of the exception), seems to be fixed in later versions of joblib. But scikit-learn is still using an old version (I will submit a pull request with the changed file soon).
A temporary workaround would be to install your own version of joblib using
easy_install joblib
and then go to the sklearn/exterlan folder, remove/rename the joblib folder, and create a symbolic link to your own joblib using:
ln -s /path/to/joblib joblib
EDIT: Seems somebody has had already fixed the problem. My version was also old.
I have searched this site top to bottom yet have not found a single way to actually accomplish what I want in Python3x. This is a simple toy app so I figured I could write some simple test cases in asserts and call it a day. It does generate reports and such so I would like to make sure my code doesn't do anything wonky upon changes.
My current directory structure is: (only relevant parts included)
project
-model
__init__.py
my_file.py
-test
my_file_test.py
I am having a hell of a time getting my_file_test.py to import my_file.py.
Like I've said. I've searched this site top to bottom and no solution has worked. My version of Python is 3.2.3 running on Fedora 17.
Previously tried attempts:
https://stackoverflow.com/questions/5078590/dynamic-imports-relative-imports-in-python-3
Importing modules from parent folder
Can anyone explain python's relative imports?
How to accomplish relative import in python
In virtually every attempt I get an error to the effect of:
ImportError: No module named *
OR
ValueError: Attempted relative import in non-package
What is going on here. I have tried every accepted answer on SO as well as all over the interwebs. Not doing anything that fancy here but as a .NET/Java/Ruby programmer this is proving to be the absolute definition of intuitiveness.
EDIT: If it matters I tried loading the class that I am trying to import in the REPL and I get the following:
>>> import datafileclass
>>> datafileclass.methods
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
>>> x = datafileclass('sample_data/sample_input.csv')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'module' object is not callable
If it matters...I know the functionality in the class works but I can't import it which in the now is causing an inability to test. In the future will certainly cause integration issues. (names changed to protect the innocent)
getting within a couple of weeks of desired functionality for this iteration of the library...any help could be useful. Would have done it in Ruby but the client wants the Python as a learning experience,
Structure your code like this:
project
-model
__init__.py
my_file.py
-tests
__init__.py
test_my_file.py
Importantly, your tests directory should also be a module directory (have an empty __init__.py file in it).
Then in test_my_file.py use from model import my_file, and from the top directory run python -m tests.test_my_file. This is invoking test_my_file as a module, which results in Python setting up its import path to include your top level.
Even better, you can use pytest or nose, and running py.test will pick up the tests automatically.
I realise this doesn't answer your question, but it's going to be a lot easier for you to work with Python standard practices rather than against them. That means structuring your project with tests in their own top-level directory.
I can't seem to get cairo regions working in within
using the gintrospection.
For example
from gi.repository import cairo
reg = cairo.Region()
will give me
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
MemoryError
and trying to get a region from Gdk.get_clip_region() will give me
return info.invoke(*args)
TypeError: Couldn't find conversion for foreign struct 'cairo.Region'
What obvious thing am I missing? I can't find a way to iniatilize the library, and can't imagine you would need to for regions which seem like a simple struct. I don't know why gdk can't find the cairo types, and am not aware if I"m supposed to show it the way somehow.
Apparently you need to use the regular cairo bindings, even when you use introspection for everything else.
So just import cairo.
(I'm not sure why gi.repository.cairo exists...)
And the "Couldn't find conversion" error will go away when you have all the necessary libraries (e.g. on Ubuntu you need the python-gi-cairo package in addition to python-cairo (or the equivalent python3 packages)).
