QUESTION
I am trying to do a simple read and count of a small parquet file (10K records) using dask-yarn
on an AWS EMR cluster with one master and one worker node, both are m5.xlarge
instances.
I am trying to execute the following code just to test my cluster:
...ANSWER
Answered 2021-Apr-29 at 12:43Your dask and distributed versions have gone out of sync, 2021.4.0 versus 2021.4.1. Updating dask should fix this. Note that you need to ensure that the exact same versions are also in the environment you are using for YARN.

I have a problem with updating packages in conda. The list of my installed packages is:

Answered 2021-Apr-14 at 20:26Channel pypi means that the package was installed with pip. You may need to upgrade it with pip as well
QUESTION
All of my virtual environments work fine, except for one in which the jupyter notebook won't connect for kernel. This environment has Zipline in it, so I expect there is some dependency that is a problem there, even though I installed all packages with Conda.
I've read the question and answers here, and unfortunately downgrading tornado to 5.1.1 didn't work nor do I get ValueErrors. I am, however, getting an AssertionError that appears related to the Class NSProcessInfo.
I'm on an M1 Mac. Log from terminal showing the error below, and my environment file is below that. Can someone help me get this kernel working? Thank you!

QUESTION
There is a web page with a large piece of text on it.
I want to configure the state to perform a certain action if curl returns an error.
If the variable doesn't contain 'StatusDescription : OK'
How can I set up a check for a piece of text that is inside a variable
...ANSWER
Answered 2021-Mar-10 at 10:54I want to configure the state to perform a certain action if curl returns an error.
There is a Salt state called http which can query
a URL and return the status. Using this (instead of curl
) we can check for the status code(s) (200, 201, etc.), as well as matching text. Then we can use requisites to run subsequent states depending on the success/failure of the http.query
.
Example:
I have added a check for status code of 200, you can omit - status: 200
if you don't care about the status code.
QUESTION
During the execution of the state, the manager "Chocolate" installs the package RealVNC (Program Files\Real VNC) Next, I create a key in the registry. I want the keys to be created only if the VNC installation was successful. I have tried
...ANSWER
Answered 2021-Feb-02 at 06:08The requisites that we mention, such as require
, watch
, etc. should be references to other states that are "scheduled" to run on the targets.
About watch
Even though the path is created by installing the "realvnc" package, there is no Salt state to handle the path. That is why it is showing the error.
Quoting from documentation for watch
:
A
watch
requisite is used to add additional behavior when there are changes in other states.
So if you want to watch on a file, then there should be a state that "handles" the file using the file
module.
About require
Also, while specifying require
you are referring to pkg
module, so Saltstack would look for pkg.installed
for realvnc. Whereas you are using chocolatey.installed
.
So with below modifications it should work fine.
QUESTION
Created a new compute instance in Azure ML and trained a model with out any issue. I wanted to draw a pairplot using seaborn
but I keep getting the error "ImportError: No module named seaborn"
I ran !conda list
and I can see seaborn in the list
ANSWER
Answered 2020-Sep-07 at 04:17I just did the following and wasn't able to reproduce your error:
- make a new compute instance
- open it up using JupyterLab
- open a new terminal
conda activate azureml_py36
conda install seaborn -y
- open a new notebook and run
import seaborn as sns
- Are you using the kernel,
Python 3.6 - AzureML
(i.e. theazureml_py36
conda env)? - Have you tried restarting the kernel and/or creating a new compute instance?
QUESTION
I'm going to use rasterio in python. I downloaded rasterio via
...ANSWER
Answered 2020-Sep-22 at 05:37I've got some experience with rasterio, but I am not nearly a master with it. If I remember correctly, rasterio requires you to have installed the program GDAL(both binaries and python utilities), and some other dependencies listed on the PyPi page. I don't use conda at the moment, I like to use the regular python 3.8 installer with pip. Given what I'm seeing with your installation, I would uninstall rasterio and follow a different installation procedure.
I follow the instructions listed here: https://rasterio.readthedocs.io/en/latest/installation.html
This page also has separate instructions for those using Anaconda.
The GDAL installation is by far the most annoying but once it's done, the hard part is over. The python utilities for both rasterio and gdal can be found here:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal
The second link is also provided on the PyPi page but I like to keep it bookmarked because there's a lot of good resources there!
QUESTION
I want to download all the python packages mentioned in the requirement.txt to a folder in Linux. I don't want to install them. I just need to download them.
python version is 3.6
list of packages in the requirement.txt
...ANSWER
Answered 2020-Jun-30 at 21:01The documentation gives what you want : pip download
pip download does the same resolution and downloading as pip install, but instead of installing the dependencies, it collects the downloaded distributions into the directory provided
So you may try these option with pip download :
QUESTION
I am quite familiar with Dask distributed for CPUs. I'd like to explore a transition to running my code on GPU cores. When I submit a task to the LocalCUDACluster I get this error:
...ANSWER
Answered 2020-Jun-13 at 15:37It looks like this question has an answer in the comments. I'm going to copy a response from Nick Becker
Dask's distributed scheduler is single threaded (CPU and GPU), and Dask-CUDA uses a one worker per GPU model. This means that each task assigned to a given GPU will run serially, but that the task itself will use the GPU for parallelized computation. You may want to look at the Dask documentation and explore Dask.Array (which also supports GPU arrays).
QUESTION
what is difference between spacy.load('en_core_web_sm')
and spacy.load('en')
? This link explains different model sizes. But i am still not clear how spacy.load('en_core_web_sm')
and spacy.load('en')
differ
spacy.load('en')
runs fine for me. But the spacy.load('en_core_web_sm')
throws error
i have installed spacy
as below. when i go to jupyter notebook and run command nlp = spacy.load('en_core_web_sm')
I get the below error
ANSWER
Answered 2019-Jan-28 at 22:45The answer to your misunderstanding is a Unix concept, softlinks which we could say that in Windows are similar to shortcuts. Let's explain this.
When you spacy download en
, spaCy tries to find the best small model that matches your spaCy distribution. The small model that I am talking about defaults to en_core_web_sm
which can be found in different variations which correspond to the different spaCy versions (for example spacy
, spacy-nightly
have en_core_web_sm
of different sizes).
When spaCy finds the best model for you, it downloads it and then links the name en
to the package it downloaded, e.g. en_core_web_sm
. That basically means that whenever you refer to en
you will be referring to en_core_web_sm
. In other words, en
after linking is not a "real" package, is just a name for en_core_web_sm
.
However, it doesn't work the other way. You can't refer directly to en_core_web_sm
because your system doesn't know you have it installed. When you did spacy download en
you basically did a pip install. So pip knows that you have a package named en
installed for your python distribution, but knows nothing about the package en_core_web_sm
. This package is just replacing package en
when you import it, which means that package en
is just a softlink to en_core_web_sm
.
Of course, you can directly download en_core_web_sm
, using the command: python -m spacy download en_core_web_sm
, or you can even link the name en
to other models as well. For example, you could do python -m spacy download en_core_web_lg
and then python -m spacy link en_core_web_lg en
. That would make
en
a name for en_core_web_lg
, which is a large spaCy model for the English language.
Hope it is clear now :)

Install msgpack-python
You can use msgpack-python like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
