I installed Cassandra on Big Sur 11.4 using homebrew, and when I tried to run cqlsh, I received this error.
isaackim#Isaacs-MacBook-Pro bin % cqlsh

I previously had Anaconda3 installed, and received the same error (the only difference was the path to cqlsh.py). I thought it might be an issue with Anaconda so I uninstalled Anaconda entirely, then I reinstalled Cassandra using homebrew.
I would appreciate any and all suggestions. Thanks in advance.
Thanks to Alex Ott's suggestion, I managed to replicate the issue you posted by creating a bad ~/.cassandra/cqlshrc configuration file which only contains the following line:
username = alice
As this error suggests:
ConfigParser.MissingSectionHeaderError: File contains no section headers.
the configuration parser detected that there are no section headers in the file. Section headers are line entries enclosed in square brackets ([header_name]). For example:
[authentication]
username = alice
password = Som3Comp7exPa$$word
Review your cqlshrc and make the necessary corrections. If necessary, use the example cqlshrc.sample file in conf/. Cheers!

when i install a package in old venv,as below:

i don't know how to handle with this problem.I will appreciated it if any one can help.Thanks in advance!
Issues with KeyError can result from malformed configuration files. Please check your .condarc files are not corrupted (should be valid YAML). These can be located in three locations:
user home (~/.condarc)
Conda environment prefix (e.g., /home/my/anaconda3/.condarc, for OP)
working directory
It also should be noted that it appears to be looking for a key pkgs dirs rather than the standard pkgs_dirs. Perhaps someone ran a conda config --set 'pkgs dirs' '/path/to/blah' by mistake?
I am trying to install openstack on an VM ubuntu server.
I git clone the devstack repository and I am launching the ./stack.sh file
However I have this error. I guess it is a simple utf-8 problem but I don't knwow how how to resolve it.
File "/home/stack/devstack/tools/outfilter.py", line 104, in <module> sys.exit(main)) File "/home/stack/devstack/tools/outfilter.py", line 98, in main outfile.write(ts_line.encode('utf-8'))
UnicodeError: 'utf-8' codec can't encode characters in position 110-112: surrogates not allowed
Thank you for your help
You'd want to edit the /devstack/tools/outfilter.py file and edit line 98 to add a 'surrogatepass' parameter. This forces surrogate pairs to be resolved into the corresponding codepoint outside the BMP.
outfile.write(ts_line.encode('utf-8','surrogatepass'))
This got me through that error.
As I have very little knowledge about Linux, pretty much all I can do is copy and paste things from a good tutorial and in most cases simply hope nothing goes wrong. I really tried finding a solution on my own and searching the internet but to no avail (I found a number of quite similar things but no solution I understood enough to be able to adapt it on my own to fix my problem).
I've installed an osm tile server using this amazing tutorial and it works like a charm. Now I want to install umap, using this tutorial.
Everything works fine until I get to the line "umap collectstatic". The error I get is this:

Now, I get the something might be wrong with a setting in a config file somewhere, but changing the directory in local.py
doesn't seem to do anything (like I have set it to STATIC_ROOT = '/home/xxx_myusername_xxx/umap/var/static') - I have no idea where this "/home/ybon/Code/..." path even comes from! What settings ?
I sure didn't specify THIS path anywhere! And the folder is indeed nowhere to be found on my machine. Maybe using virtualenv is somehow generating it, and I can't find it on my machine because it IS virtual (as in "not really there physically") but this is just a very wild guess and I don't really know what I'm talking about.
(I tried running the command with and without sudo and it doesn't change anything).
I have always wanted to install a tile server and have tried the tutorials you have given today. So I'm a learner like you!
Installing the Tile Server with the tutorial https://www.linuxbabe.com/linux-server/openstreetmap-tile-server-ubuntu-16-04 was really straightforward. I only used the part for Rhineland Palatinate.
With Umap (https://umap-project.readthedocs.io/en/latest/ubuntu/#tutorial) I had some problems.
1. A port was used twice. I changed the port for Apache.
2. After creating the local configuration (wget https://raw.githubusercontent.com/umap-project/umap/master/umap/settings/local.py.sample -O /etc/umap/umap.conf) this file was not immediately recognized. I helped myself by changing the file before executing the command "umap migrate".
I have made the following changes:
# For static deployment
STATIC_ROOT = '/etc/umap/var/static'
# For users' statics (geojson mainly)
MEDIA_ROOT = '/etc/umap/umap/var/data'
# Umap Settings
UMAP_SETTINGS='/etc/umap/umap.conf'
STATIC_ROOT und MEDIA_ROOT I have changed, because so the user umap has all permissions. Then I set the envirement variable UMAP_SETTINGS because otherwise the settings file /etc/umap/umap.conf is not found.
( I also have no idea where this "/home/ybon/Code/..." path comes from. After the configuration file is properly loaded, the path is loaded from the configuration file. That's why that's not important anymore. )
Now I could use the following commands without errors:
(venv) $ umap collectstatic
Loaded local config from /etc/umap/umap.conf

Hi text mining champions,
I'm using Anaconda with NLTK v3.2 on Windows 10.(client's environment)
When I try to POS tag, I keep getting a URLLIB2 error:
URLError: <urlopen error unknown url type: c>
It seems urllib2 is unable to recognize windows paths? How can I work around this?
The command is simple as:
nltk.pos_tag(nltk.word_tokenize("Hello World"))
edit:
There is a duplicate question, however I think the answers obtained here by manan and alvas are a better fix.
EDITED
This issue has been resolved from NLTK v3.2.1. Upgrading your NLTK version would resolve the issue, e.g. pip install -U nltk.
I faced the same issue and the error encountered was as follows;
Traceback (most recent call last):

urllib2.URLError: <urlopen error unknown url type: c>
The URLError that you mentioned was due to a bug in the perceptron.py file within the NLTK library for Windows.
In my machine, the file is at this location
C:\Python27\Lib\site-packages\nltk-3.2-py2.7.egg\nltk\tag\perceptron.py
(Basically look at an equivalent location within yours wherever you have the Python27 folder)
The bug was basically in the code to find the corresponding location for the averaged_perceptron_tagger within your machine. One can have a look at the line 801 and 924 mentioned in the data.py file regarding this.
I think the NLTK developer community recently fixed this bug in the code. Have a look at this commit made to their code a few days back.
https://github.com/nltk/nltk/commit/d3de14e58215beebdccc7b76c044109f6197d1d9#diff-26b258372e0d13c2543de8dbb1841252
The snippet where the change was made is as follows;
self.tagdict = {}
self.classes = set()
if load:
AP_MODEL_LOC = 'file:'+str(find('taggers/averaged_perceptron_tagger/'+PICKLE))
self.load(AP_MODEL_LOC)
# Initially it was:AP_MODEL_LOC = str(find('taggers/averaged_perceptron_tagger/'+PICKLE))
def tag(self, tokens):
Updating the file to the most recent commit worked for me and was able to use the nltk.pos_tag command. I believe this would resolve your problem as well (assuming you have everything else set up).
EDITED
This issue has been resolved from NLTK v3.2.1. Please upgrade your NLTK!
First read #MananVyas answer for the why:
https://stackoverflow.com/a/35902494/610569
Here's the how, without downgrading to NLTK v3.1, using NLTK 3.2, you can use this "hack":
>>> from nltk.tag import PerceptronTagger
>>> from nltk.data import find
>>> PICKLE = "averaged_perceptron_tagger.pickle"
>>> AP_MODEL_LOC = 'file:'+str(find('taggers/averaged_perceptron_tagger/'+PICKLE))
>>> tagger = PerceptronTagger(load=False)
>>> tagger.load(AP_MODEL_LOC)
>>> pos_tag = tagger.tag
>>> pos_tag('The quick brown fox jumps over the lazy dog'.split())
[('The', 'DT'), ('quick', 'JJ'), ('brown', 'NN'), ('fox', 'NN'), ('jumps', 'VBZ'), ('over', 'IN'), ('the', 'DT'), ('lazy', 'JJ'), ('dog', 'NN')]
I faced the same issue a while back.
Solution:
nltk.download('averaged_perceptron_tagger')

I placed the chromium project on an external hard disk as you did, and I got the same error.
Perhaps you should try the syncing stuff in your internal drive.
Haven't tried. Hope that help.
