I downloaded nltk tagset help is not working.
Whenever I try to access tagset meanings by:-
nltk.help.upenn_tagset('NN')
I get result as :-
Traceback (most recent call last):

So what am I doing wrong here?
As nltk is telling you, it searched for the file help/tagsets/upenn_tagset.pickle in the directories:

- 'C:\\nltk_data'
- 'D:\\nltk_data'

And could not find it.
Is it there?
If not, use nltk.download() to get it, and make sure it's in one of these directories.

Hi ,
Check for above tagged image to summarize what exactly needs to be downloaded.
One of the fastest and easiest way to resolve this issue by downloading the help_tagsets from nltk.download() .
One can follow below steps:-
open your jupyter notebook or python shell in your OS(thru terminal).
ask for nltk.download() - (shell/jupyter) - it will open the GUI.
search the help_datasets in ALL PACKAGES column.
Just download it :-) Here you go .

I've been working on writing some mkdocs documentation which includes mermaid diagrams that I'd like to keep in the markdown files instead of turning into images and embedding them
I came across this great solution here: https://github.com/squidfunk/mkdocs-material/issues/693#issuecomment-411885426
Which uses the super-fences feature of the pymdown-extensions plugin to create a custom code block which renders the mermaid diagrams inside the code block.
It works in mkdocs running locally, but when I submit the configuration file to readthedocs it fails the yaml validation
Your mkdocs.yml could not be loaded, possibly due to a syntax error (line 18, column 19)
Line 18 in the mkdocs.yml config file is the section which calls the superfences python class
format: !!python/name:pymdownx.superfences.fence_div_format
Looking in the yaml specification https://yaml.org/spec/1.2/spec.html Shows that !! is for an explicit tag and it seems to have been part of the spec for quite some time ( back to version 1). I've tried making the value a string but this then causes issue with python reading it as a string
Does anyone know if readthedocs supports this or have you been able to get this working some other way?
ReadTheDocs is parsing the mkdocs.yaml file using pyyaml and it seems that it does not recognize !!.
For example:
>>> import yaml
>>> document = """
a: 1
b:
c: 3
d: !!4
"""
>>> print(yaml.dump(yaml.load(document)))
<stdin>:1: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.

I am new at programming and I have a question regarding the following error.
I am using python 2.7., and I have the following script to create a simple graph (example taken from python CrashCourse by Eric Matthes):
import matplotlib.pyplot as plt
squares = [1,4,9,16,25]
plt.plot(squares, linewitdth = 5)
#Set chart title and lable axes.
plt.title("Square Numbers", fontsize = 24)
plt.xlabel("Value", fontsize = 14)
plt.ylabel("Square of Value", fontsize = 14)
# Set size of tick labels
plt.tick_params(axis = "both", labelsize = 14)
plt.show()
When I ran this script in WindowsPowerShell I got the following error:
Traceback (most recent call last): File "mpl_squares.py", line 1, in <module>
import matplotlib.pyplot as plt
File "C:\Users\Roger\Anaconda2\lib\sitepackages\matplotlib\__init__.py, line 134, in <module> from ._version import get_versions
File "C:\Users\Roger\Anaconda2\lib\site-packages\matplotlib\_version.py", line 7, in <module> import json
File "C:\Users\Roger\Desktop\lpthw\json.py", line 7, in <module>
AttributeError: "module" object has no attribute "dump"
In other script I had the same problem when importing this module, then I found
a solution by replacing the line "import json" by "import simplejson, and It worked well.
Here is the solution I found back then:
json is simplejson, added to the stdlib. But since json was added in 2.6, simplejson has the advantage of working on more Python versions (2.4+).
simplejson is also updated more frequently than Python, so if you need (or want) the latest version, it's best to use simplejson itself, if possible.
A good practice, in my opinion, is to use one or the other as a fallback.
try: import simplejson as json
except ImportError: import json
Now I checkt in the error I got the module it is poiting out "_version.py"
This is the information contained in this file:
# This file was generated by 'versioneer.py' (0.15) from
# revision-control system data, or from the parent directory name of an
# unpacked source archive. Distribution tarballs contain a pre-generated
#copy
# of this file.
import json
import sys
version_json = '''
{
"dirty": false,
"error": null,
"full-revisionid": "26382a72ea234ee0efd40543c8ae4a30cffc4f0d",
"version": "1.5.3"
}
''' # END VERSION_JSON
def get_versions():
return json.loads(version_json)
Question:
Do you think I would have to fix something in the _version.py module by replacing
import json for import simplejson and the function added in the module?
I am thinking in a workaround to fix the problem but I don't wanna modify anything from the _version.py if it make things worse. Thank you very much for your comments and suggestions.
Best Regards
It seems like your C:\Users\Roger\Desktop\lpthw\json.py gets imported instead of Python's built-in json module.
Did you somehow add that folder (C:\Users\Roger\Desktop\lpthw) to your PYTHONPATH, e.g. with sys.path.append() or the PYTHONPATH variable? Read more about how Python finds modules.
The reason why the fix with simplejson works is that it is not overridden by some other module of the same name.
Try renaming C:\Users\Roger\Desktop\lpthw\json.py to something like C:\Users\Roger\Desktop\lpthw\myjson.py and also try to figure out how that lpthw folder made it into your PYTHONPATH.
Explanation
This link is where you are sent to after entering in your hardware stats (hashrate, power, power cost, etc.). On the top bar (below the blue Twitter follow button) is a link to a JSON file created after the page loads with the hardware stats information entered; clicking on that JSON link redirects you to another URL (https://whattomine.com/asic.json).
Goal
My goal is to access that JSON file directly after manipulating the values in the URL string via the terminal. For example, if I would like to change hashrate from 100 to 150 in this portion of the URL:
[sha256_hr]=100& ---> [sha256_hr]=150&
After the URL manipulations (like above, but not limited to), I would like to receive the JSON output so that I can pick-out the desired data.
My Code
Advisory: I started Python programming ~June 2017, please forgive.
import json
import pandas as pd
import urllib2
import requests
hashrate_ghs = float(raw_input('Hash Rate (TH/s): '))
power_W = float(raw_input('Power of Miner (W): '))
electric_cost = float(raw_input('Cost of Power ($/kWh): '))
hashrate_ths = hashrate_ghs * 1000
initial_request = ('https://whattomine.com/asic?utf8=%E2%9C%93&sha256f=true&factor[sha256_hr]={0}&factor[sha256_p]={1}&factor[cost]={2}&sort=Profitability24&volume=0&revenue=24h&factor[exchanges][]=&factor[exchanges][]=bittrex&dataset=Main&commit=Calculate'.format(hashrate_ths, power_W, electric_cost))
data_stream_mine = urllib2.Request(initial_request)
json_data = requests.get('https://whattomine.com/asic.json')
print json_data
Error from My Code
I am getting an HTTPS handshake error. This is where my Python freshness is second most blatantly visible:
Traceback (most recent call last):
File "calc_1.py", line 16, in <module>
s.get('https://whattomine.com/asic.json')

resp = self.send(prep, **send_kwargs)

r = adapter.send(request, **kwargs)
File "/Library/Python/2.7/site-packages/requests/adapters.py", line 506, in send
raise SSLError(e, request=request)

Thank you for your help and time!
Please advise me of any changes or for more information concerning this question.
This is just a comment. The following approach would suffice (Python 3).
import requests
initial_request = 'http://whattomine.com/asic.json?utf8=1&dataset=Main&commit=Calculate'
json_data = requests.get(initial_request)
print(json_data.json())
The key point here this part - put .json in your initial_request and it will be enough.
You may add all you parameters as you did in the query part after ? sign
It looks like a few others faced similar problems.
While for some it seemed to be like a pyOpenSSL version issue, uninstalling and reinstalling which has fixed the problem. Another older answer in SO asks to do the following.
My code:
LOAD CSV FROM "C:\Users\Elmar\Desktop\tmp-raise.csv" AS line
WITH line
RETURN line
The error that it gives:
Invalid input ':': expected 'o/O' (line 1, column 18 (offset: 17))
"LOAD CSV FROM "C:\Users\Elmar\Desktop\tmp-raise.csv" AS line"
^
I have also tried:
USING PERIODIC COMMIT 10000
LOAD CSV FROM ""C:\Users\Elmar\Desktop\tmp-raise.csv" AS line
WITH line
RETURN line
What is the problem? Can anyone help me?
According to the CSV import guide, your path should be prefixed with file: and should use forward slashes. The example path given in the guide for windows is file:c:/path/to/data.csv (though I have seen example paths starting with file://). Give this a try:
USING PERIODIC COMMIT 10000
LOAD CSV FROM 'file:c:/Users/Elmar/Desktop/tmp-raise.csv' AS line
WITH line
RETURN line
If that doesn't work, give it a try with file:// as the path prefix.
EDIT: Looks like CSV loads use a relative path from the default.graphdb/import folder. I had thought that was for Mac/Unix only, but it looks like Windows does the same. If you move CSVs you want to import into the import folder, you should be able to load them using file:///theFileName.csv
Load csv from "file:///C:/xyz.csv" as line
return line
The above code works well. But do comment out the configuration
dbms.directories.import=import
in the settings.
Other solution is you can drop a (.txt, .cyp, .cql) file in the drag to import box.
The cause of the problem is obvious after the fact, but I'd like to share the not-too-obvious cause here.
When running code such as
import jinja2
templateLoader = jinja2.FileSystemLoader(searchpath=".")
templateEnv = jinja2.Environment(loader=templateLoader,
trim_blocks=True,
lstrip_blocks=True)
htmlTemplateFile = 'file.jinja.html'
htmlTemplate = templateEnv.get_template(htmlTemplateFile)
if you get this problem:
Traceback (most recent call last):
...
File "file.py", line xyz, in some_func
htmlTemplate = templateEnv.get_template(htmlTemplateFile)
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/jinja2/environment.py", line 812, in get_template
return self._load_template(name, self.make_globals(globals))
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/jinja2/environment.py", line 774, in _load_template
cache_key = self.loader.get_source(self, name)[1]
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/jinja2/loaders.py", line 187, in get_source
raise TemplateNotFound(template)
jinja2.exceptions.TemplateNotFound: file.jinja.html
you may find the discussions online point that this issue must have something to do with the interaction of jinja2 with flask, with GAE, with Pyramid, or with SQL, and it may indeed be that your templates are not in a "template" folder, but this problem can arise from the interaction of jinja2 and the os module.
The culprit is changing the current directory by, for instance,
import os
os.chdir(someDir)
If templateEnv.get_template(...) is called past this point, jinja2 will look for the templates in the "current" dir, even if that has changed.
Since module os provides os.chdir but not os.pushdir/os.popdir, one has to either simulate the latter pair or avoid chdir altogether.
