The nltk module is running with other libraries in the corpus folder.
My Code
I've already tried putting 'import nltk' at first but it is still the same, and also I've tried 'from nltk.tokenize import 'PunktSentenceTokenizer'. I don't know why the Python shell can't find the definition of the nltk. How should I address this? I am still learning how to write and code python.
First, install the nltk package by typing...
pip install nltk
Then you need to import it...
import nltk
You misspelled the name of the package in your file, you have used ntlk instead of nltk
change
tagged = ntlk.pos_tag(words)
to
tagged = nltk.pos_tag(words)

I have an installed python module with cython extensions. Now I am writing a second (different) cython module that wants to import extensions from the installed cython module. However, it is not able to find the definition files of the first module.
The first module has .../python3.8/site-packages/plexim[version]/EGG-INFO/SOURCES.txt as follows:
setup.py
...
plexsim/models.cpp
plexsim/models.pxd
...
Which looks good as the pxd is packed with the module.
In the other module I want to import the pxd from models.pxd. However, when I try to install my other extensions module it cannot find the extension definition when doing
from plexsim.models cimport *
How do I package the data correctly such that the other module sees the definition from the already installed module?
My setup.py looks a follows
setup(
package_dir = {"" : "imi"
},
namespace_packages = find_namespace_packages (include = ["imi.*"]),
package_data = {"": "*.pxd *.pyx".split(),
ext_modules = cythonize(
exts,
language_level = 3,
compiler_directives = cdirectives,
nthreads = mp.cpu_count(),
),\
Thanks
After hours of debugging I figured the path-issue out. Adding __init__.pxd to the module seemed to have cured the problem. For future reference be mindful of whether setuptools actually find the pxd files.
_caffe.so is present in the caffe/python/caffe folder
Have set the path variable as export PYTHONPATH=/home/itstudent1/caffe/python:$PYTHONPATH.
make pycaffe was also successful.
I am not understanding what else might be the cause for this error. I am able to import caffe in python.
File
"/home/itstudent1/MajorProject/densecap-master/lib/tools/../../python/caffe/pycaffe.py",
line 13, in
from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \ ImportError: No module named _caffe
It seems like you have two versions of caffe:
one in /home/itstudent1/caffe and another in /home/itstudent1/MajorProject/densecap-master.
While the first version is built and compiled, the later is not and your import looks for _caffe.so in the later.
This page was inspiring me to try out spark-csv for reading .csv file in PySpark
I found a couple of posts such as this describing how to use spark-csv
But I am not able to initialize the ipython instance by including either the .jar file or package extension in the start-up that could be done through spark-shell.
That is, instead of
ipython notebook --profile=pyspark
I tried out
ipython notebook --profile=pyspark --packages com.databricks:spark-csv_2.10:1.0.3
but it is not supported.
Please advise.
You can simply pass it in the PYSPARK_SUBMIT_ARGS variable. For example:
export PACKAGES="com.databricks:spark-csv_2.11:1.3.0"
export PYSPARK_SUBMIT_ARGS="--packages ${PACKAGES} pyspark-shell"
These property can be also set dynamically in your code before SparkContext / SparkSession and corresponding JVM have been started:
packages = "com.databricks:spark-csv_2.11:1.3.0"
os.environ["PYSPARK_SUBMIT_ARGS"] = (
"--packages {0} pyspark-shell".format(packages)
)
I believe you can also add this as a variable to your spark-defaults.conf file. So something like:
spark.jars.packages com.databricks:spark-csv_2.10:1.3.0
This will load the spark-csv library into PySpark every time you launch the driver.
Obviously zero's answer is more flexible because you can add these lines to your PySpark app before you import the PySpark package:
import os
os.environ['PYSPARK_SUBMIT_ARGS'] = '--packages com.databricks:spark-csv_2.10:1.3.0 pyspark-shell'
from pyspark import SparkContext, SparkConf
This way you are only importing the packages you actually need for your script.
I am trying to import sqlalchemy in a module in a subpackage.
Here is my folder layout
PloneInstance
my.package
my
package
subpackage
In the buildout.cfg file of the root folder, I add "sqlalchemy" to the eggs.
In my.package, in configure.zcml, I add:
In the subpackage, I have a blank __init__.py file, a configure.zcml file, and a file called mymodule.py
In mymodule.py I have a line for importing sqlalchemy
import sqlalchemy
Unfortunately, I am getting an error when I try to run an instance:
ImportError: No module named sqlalchemy
I'm assuming I am missing a step. How do I properly import python packages?
Thank you in advance. I apologize if my terminology is off.
Edit:
The module in question I am importing from turned out to be zope.sqlalchemy.
I accidentally overlooked this because prior to moving files to a subpackage, the import statement for zope.sqlalchemy was working without adding zope.sqlalchemy to the eggs section of the buildout.
Look in the setup.py file at the top directory of your package. You'll find a section like:
install_requires=['setuptools',
# -*- Extra requirements: -*-
],
In place of the "Extra requirements' comment, put a comma-separated list of strings specifying your package's requirements. You may even specify versions.
Do not add standard Plone packages to the list. They're taken for granted.
Re-run buildout after specifying your requirements. The result is that the new install requires will be added to your Python environment when you start Plone.
I've had not trouble until this point directly from MXMLC command line. While compiling Actionscript 3 code I ran into a dependency problem.
import flash.filesystem;
and I get
Error: Definition flash:filesystem could not be found
There are another or two file-related libraries such as filestream. Where can I find these standard libraries and how might I add them to my MXMLC library PATH?
What are the specific classes you are trying to use? If you want to import all of the classes in the flash.filesystem package you need a * at the end of that import statement. Otherwise you need to append the class name(s). Something like one of these:
import flash.filesystem.*;
or
import flash.filesystem.File;
The other thing that might be an issue is the values in your flex-config.XML (or air-config.xml) file that is part of the SDK. You might need to configure this to include the classes in the AIR sdk, etc.
