The StanfordSegmenter does not have an interface in nltk, different from the case of StanfordPOStagger or StanfordNER. So to use it, basically I have to create an interface manually for StanfordSegmenter, namely stanford_segmenter.py under ../nltk/tokenize/. I follow the instructions here http://textminingonline.com/tag/chinese-word-segmenter
However, when I tried to run this from nltk.tokenize.stanford_segmenter import stanford_segmenter, I got an error
msg Traceback (most recent call last):
File "C:\Users\qubo\Desktop\stanfordparserexp.py", line 48, in <module>
from nltk.tokenize.stanford_segmenter import stanford_segmenter
ImportError: No module named stanford_segmenter
[Finished in 0.6s]
The instructions mentioned to reinstall nltk after creating the stanford_segmenter.py. I don't quite get the point but so I did. However, the process can hardly be called 'reinstall', but rather a detaching and reconnecting nltk to python libs.
I'm using Windows 64 and Python 2.7.11. NLTK and all relevant pkgs are updated to the latest version. Wonder if you guys can shed some light on this. Thank you all so much.
I was able to import the module by running the following code:
import imp
yourmodule = imp.load_source("module_name.py", "/path/to/module_name.py")
yourclass = yourmodule.TheClass()
yourclass is an instance of the class and TheClass is the name of the class you want to create the obj in. This is similar to the use of:
from pkg_name.module_name import TheClass
So in the case of StanfordSegmenter, the complete lines of code is as follows:
# -*- coding: utf-8 -*-
import imp
import os
ini_path = 'D:/jars/stanford-segmenter-2015-04-20/'
os.environ['STANFORD_SEGMENTER'] = ini_path + 'stanford-segmenter-3.5.2.jar'
stanford_segmenter = imp.load_source("stanford_segmenter", "C:/Users/qubo/Miniconda2/pkgs/nltk-3.1-py27_0/Lib/site-packages/nltk/tokenize/stanford_segmenter.py")
seg = stanford_segmenter.StanfordSegmenter(path_to_model='D:/jars/stanford-segmenter-2015-04-20/data/pku.gz', path_to_jar='D:/jars/stanford-segmenter-2015-04-20/stanford-segmenter-3.5.2.jar', path_to_dict='D:/jars/stanford-segmenter-2015-04-20/data/dict-chris6.ser.gz', path_to_sihan_corpora_dict='D:/jars/stanford-segmenter-2015-04-20/data')
sent = '我有一只小毛驴我从来也不骑。'
text = seg.segment(sent.decode('utf-8'))

ImportError Traceback (most recent call last)

6 import numpy as np

----> 8 from pytorchcv import load_mnist, train, plot_results, plot_convolution, display_dataset
9 load_mnist(batch_size=128)
ImportError: cannot import name 'load_mnist' from 'pytorchcv' (/anaconda/envs/py37_pytorch/lib/python3.7/site-packages/pytorchcv/__init__.py)
How can fix this bug?
I use python 3.7 and Jupiter notebook. The code in Pytorch Fundamental of Microsoft: Link https://learn.microsoft.com/en-gb/learn/modules/intro-computer-vision-pytorch/5-convolutional-networks
import torch
import torch.nn as nn
import torchvision
import matplotlib.pyplot as plt
from torchinfo import summary
import numpy as np
from pytorchcv import load_mnist, train, plot_results, plot_convolution, display_dataset
load_mnist(batch_size=128)
I installed PyTorch by command: pip install pytorchcv
I assume you might have the wrong pytorchcv package. The one in pypy does not contain load_mnist
Starting from scratch you could download mnist as such:
data_train = torchvision.datasets.MNIST('./data',
download=True,train=True,transform=ToTensor()) data_test = torchvision.datasets.MNIST('./data',
download=True,train=False,transform=ToTensor())
They missed one command before importing pytorchcv.
This pytorchcv is different from pytorchcv in PyPI.
Run this before importing pytorchcv.
!wget https://raw.githubusercontent.com/MicrosoftDocs/pytorchfundamentals/main/computer-vision-pytorch/pytorchcv.py
Then it should work.
please download the prepared py file from the link https://raw.githubusercontent.com/MicrosoftDocs/pytorchfundamentals/main/computer-vision-pytorch/pytorchcv.py and put it into current folder, then VS Code could recognize it
I transferred some code from IDLE 3.5 (64 bits) to pycharm (Python 2.7). Most of the code is still working, for example I can import WD_LINE_SPACING from docx.enum.text, but for some reason I can't import WD_ALIGN_PARAGRAPH.
At first, nearly non of the imports worked, but after I did
pip install python-docx
instead of
pip install docx
most of the imports worked except for WD_ALIGN_PARAGRAPH.
# works
from __future__ import print_function
import xlrd
import xlwt
import os
import subprocess
from calendar import monthrange
import datetime
from docx import Document
from datetime import datetime
from datetime import date
from docx.enum.text import WD_LINE_SPACING
from docx.shared import Pt
# does not work
from docx.enum.text import WD_ALIGN_PARAGRAPH
I don't get any error messages but Pycharm marks the line as error:
"Cannot find reference 'WD_ALIGN_PARAGRAPH' in 'text.py'".
You can use this instead:
from docx.enum.text import WD_PARAGRAPH_ALIGNMENT
and then substitute WD_PARAGRAPH_ALIGNMENT wherever WD_ALIGN_PARAGRAPH would have appeared before.
The reason this is happening is that the actual enum object is named WD_PARAGRAPH_ALIGNMENT, and a decorator is applied that also allows it to be referenced as WD_ALIGN_PARAGRAPH (which is a little shorter, and possibly clearer). I expect the syntax checker in PyCharm is operating on direct module attributes and doesn't pick up the alias, which is resolved by the Python parser/compiler.
Interestingly, I expect your code would work fine either way. But to get rid of the annoying message you can use the base name.
If someone uses pylint it can be easily suppressed with # pylint: disable=E0611 added at the end of the import line.
I'm learning to use colorama in Python, so I installed it and I'm able to import the module with no problems from the Primary Prompt.
>>> import colorama
>>> from colorama import *
>>> print(Fore.BLUE + 'BLUE TEXT')
BLUE TEXT
Now, if I create a small piece of code like this:
#!/usr/bin/env python2.7
from colorama import *
print(Fore.BLUE + 'BLUE TEXT')
I get the following message:
File "colorama_Test.py", line 3, in <module>
from colorama import *
File "/home/olg32/Python/colorama_Test.py", line 5, in <module>
print(Fore.BLUE + 'BLUE TEXT')
NameError: name 'Fore' is not defined
Which tells me that the module is not being found. But as mentioned it was installed and tested successfully from the Primary Prompt. Could it be a path definition issue or something like that? This is the current directory where the module is installed:
usr/local/lib/python2.7/dist-packages/colorama-0.3.7-py2.7.egg
Does this path needs to be defined somewhere? Sorry I'm new on Python.
Any help would be appreciated.
Thank you.
Hopefully you have worked out the answer by now but have you tried specifying Fore?
When I use the colorama module I start with this:
import os, colorama
from colorama import Fore,Style,Back #specifying all 3 types
os.system("mode con: cols=120 lines=30") #sometimes colorama doesnt work
#when double clicking a python app so I use this to "prompt" command line
#and then it works fine colorama.init() should work too
Example code:
import os, colorama
from colorama import Fore,Style,Back
os.system("mode con: cols=120 lines=30")
print(Fore.RED + 'some red text')
print(Back.GREEN + 'and with a green background')
print(Style.DIM + 'and in dim text')
print(Style.RESET_ALL)
print('back to normal now')
If this doesnt work for you let me know :)
I use this python library which uses pyatspi (from pyatspi import …). When I run it in (L)Ubuntu 16.04, it throws the following error:
/usr/lib/python2.7/dist-packages/pyatspi/__init__.py:17: PyGIWarning: Atspi was imported without specifying a version first. Use gi.require_version('Atspi', '2.0') before import to ensure that the right version gets loaded.
from gi.repository import Atspi
Although this error message says exactly what I should do to, it doesn't work just to add the line gi.require_version('Atspi', '2.0') in /usr/lib/python2.7/dist-packages/pyatspi/__init__.py (giving NameError: name 'gi' is not defined) – what am I doing wrong?
It's necessary to import require_version from gi first, so just add:
from gi import require_version
require_version('Atspi', '2.0')
before the
from gi.repository import Atspi
line in the file given by the error message, which was /usr/lib/python2.7/dist-packages/pyatspi/__init__.py here.
Hello I am trying to install and make use of NodeboxOpenGL, the python library so I can create my own graphs with nodes and edges. But I am running into some trouble,
starting off at NodeBox OpenGL site. I downloaded NodeBox for OpenGL and then pyglet, I then did easy_install nodebox-opengl.
Note I did not do pip install
I installed pyglet from pyglet. So now I am thinking its all ready to go. I did a quick check of my c:\python27\Lib\site-packages\ location just be sure the nodebox folder was there, all seems good.
I tried the sample program that's on the site
from nodebox.graphics import *
from nodebox.graphics.physics import Flock
flock = Flock(40, 0, 0, 500, 500)
flock.sight = 300
def draw(canvas):
background(1)
fill(0, 0.75)
flock.update(cohesion=0.15)
for boid in flock:
push()
translate(boid.x, boid.y)
scale(0.5 + 1.5 * boid.depth)
rotate(boid.heading)
arrow(0, 0, 15)
pop()
canvas.fps = 30
canvas.size = 600, 400
canvas.run(draw)
tried to run it, but i keep getting this error
Traceback (most recent call last):

File "E:\Workspace\ElasticNodes\nodebox\graphics\geometry.py", line 454, in <module>
from pyglet.gl import \
ImportError: cannot import name pointer
I tried modifying the python script i.e
In your script, add the location of NodeBox to sys.path, before importing it: >>> MODULE = '/users/tom/python/nodebox' >>> import sys; if MODULE not in sys.path: sys.path.append(MODULE) >>> import nodebox
But still the same error.
I am using Python2.7, running on windows. I am not sure what I am doing wrong. Has anyone got any experience with running this library on windows. What am I doing wrong
Maybe this helps you:
In geometry.py del "pointer" import. Replace pointer(data) to POINTER(data)
I also had another error, so maybe you need add import to "shaders.py": from ctypes import c_uint
I am having a similar problem with Linux. The Nodebox-opengl site ( http://www.cityinabottle.org/nodebox/ ) says that python 2.5 or 2.6 must be used, so it is possible that the problem is that you are using 2.7.
EDIT:
Ok, I installed pyglet first, with pip (and or apt-get, I did both) and I don't get a problem with pyglet. But I still do get other problems.
