QUESTION
I want to distribute a Python package which has a closed source dependency. I am using setup.py and everything works if I also do the compilation with setup.py.
Neither answers to this question nor answers to that question solve my problem.
I have the following file structure:
...ANSWER
Answered 2021-Jun-14 at 01:07You will have to vendor the dependency. The easiest way to do that is to include the dependency inside your python package, not outside.
setuptools
requires you to include a MANIFEST.in
file to include non-package, non-python files in your distribution.
See this project for an example of how to do that.
Your project structure should look something like this:
QUESTION
I'm trying to help the owner of tkdnd generate a wheel and distribute it to Pypi so users could simply install the tkdnd extension with a simple pip install TkinterDnD2
.
I'm after this 'challange' for the last two days but could not solve it by myself so far, but I'm sure someone with a deep understanding python packaging and installing process could help as solve it in short time.
currently in order to get this extension work you need to do the following steps(as mentioned here):
- download the compiled tkdnd files for your os. now go to your base interpreter directory/tcl and copy this folder under. for example:
ANSWER
Answered 2021-Jun-05 at 17:02Just answering for the case someone else got stuck on it for weeks like I did.
You can see dist repo that pmgagne created here: https://github.com/pmgagne/tkinterdnd2
The package is not yet published on pypi but you can build a wheel and install it following the instructions on this issue I opened: https://github.com/pmgagne/tkinterdnd2/issues/5
Hopefully, the author will build and publish it soon, so you could simply do python -m pip install tkinterdnd2
and enjoy tkinter inter-windows drag and drop support!
If you don't want to build it your self here's a wheel download: tkinterdnd2-0.3.0-py2.py3-none-any.zip
extract zip and then you can do python -m pip install tkinterdnd2-0.3.0-py2.py3-none-any.whl
and then you will be able to import tkinterdnd2
in your python project.
the author did not respond so I forked it published it myself. you can now install simply using
QUESTION
I am learning Python specifically for data science and have little programming language although I'm a bit more familiar with R.
I installed some modules e.g. pandas and matplotlib, using the code:
...ANSWER
Answered 2021-Jun-05 at 03:09Python is probably not finding your pandas library, because it's installed in a folder where python is not looking into by default.
When you type "import pandas" python is going to look for a package named pandas within a list of folders set by default.
To solve your issue you can move/reinstall pandas into a folder which python searches through by default or you can add another folder to search through.
Here's a way to do it with python adding directory to sys.path /PYTHONPATH

I have a requirement for inserting SVG file into Word. Since, we cannot do this directly I am planning to convert SVG to EMF and insert it. Conversion from SVG to EMF works fine using the inkscape. However, I am unable to come up with right code for inserting it into Word. I followed the steps explained the the person Alvaro in this post. Have shown the steps followed in the attached file -
This is my code -

QUESTION
I need to have private Python packages in GCP usable in multiple projects. I haven't tried the Artifact Registry since that's still in alpha, so right now I've been trying with simple repositories, but I'm open to alternatives.
I have a Python package source code in a GCP Repository in Project A, and I have a cloud function in a repository also in Project A. In this cloud function I import the mentioned package by adding git+https://source.developers.google.com/p/project-a/r/my-python package
in my requirements.txt
file.
If I deploy this cloud function in Project A via gcloud functions
in my terminal, specifying --source=https://source.developers.google.com/projects/project-a/repos/my-cloud-function
and --project=project-a
, it works fine, and the function can successfully import the elements from the package when I call it, but if I deploy this function in Project B instead, I get the following error:
ANSWER
Answered 2021-May-25 at 21:28Artifact Registry is GA and no longer on Alpha/Beta since last year.
I replicated your issue. The error is indeed due to permissions, it didn't happened on the deployment when you remove the line on the requirements.txt
, probably because the credentials had access to both projects.
In order to make the deployment correct you have to add the permissions on the repository to the service account that makes the deployment (which is the CF service account) that can be found on Cloud Functions
- (select your Cloud Function)
- Details
, it should be something like project@appspot.gserviceaccount.com
Once you have located the service account add it to the Cloud Repository by clicking on Settings
- Permissions
and add it with at least the Source Repository Reader
role
QUESTION
I'm trying to add mecab library to aws lambda layer but it didn't work.
What I want is to tokenize Japanese and Korean languages. Tokenizing is enough.
Here's what I have done. (I referred to this site: https://towardsdatascience.com/how-to-install-python-packages-for-aws-lambda-layer-74e193c76a91 for installing python packages for aws lambda layers)
AWS EC2 docker installation.
Build docker file
ANSWER
Answered 2021-May-15 at 10:55You can create a lambda layer using docker as described in the AWS blog.
Thus you can add mecab
to your function as follows:
Create empty folder, e.g.
mylayer

I followed the instructions here to set up and remove a python lambda function (and associated AWS resources).
When I try to clean up the function, role-policy and role, the instructions failed because the CLI does not manage to find the attached role policies. In particular, if I run:
...ANSWER
Answered 2021-Apr-30 at 16:58As i can see from the image, its a managed policy and unfortunately list-role-policies only Lists the names of the inline policies that are embedded in the specified IAM role.
An IAM role can also have managed policies attached to it. To list the managed policies that are attached to a role, use ListAttachedRolePolicies
use this for example
QUESTION
I have a python package, and I am using poetry
for dependency management and packaging.
In my local environment, I am using tox
to test the package in multiple python version.
How can I use GitHub actions to test my package, everytime there is a push or pull request ?
Things that I have tried:
- https://github.com/actions/starter-workflows/blob/main/ci/python-package.yml
(this official action installs via
pip
andrequirements.txt
, but I am using poetry) - https://github.com/abatilo/actions-poetry
(this action, can install poetry, but using
pip
, which is not recommended by poetry, as it can cause conflict with my application dependencies, see issue ) - https://github.com/ymyzk/tox-gh-actions (should I use this ? why not rather run
pytest
in every matrix (of github actions), this action seems to defeat the purpose of tox)
I want to test my python code in gh-actions.
in my situation, what should I actually use ?
what are the best practices ? and most optimum tool
...ANSWER
Answered 2021-Apr-14 at 12:11The beauty of tox
is that you can run it both locally and on CI.
You have a high chance of a successful CI when it passes locally, and also you only need to define the test requirements and the test setup once, in one file.
To do so, I recommend using the mentioned tox-gh-actions
.
I applied this pattern to dozens of repositories with success.
I recommend the following blog post which gives a great introduction to this setup:
https://hynek.me/articles/python-github-actions/
You can have a look at the tox.ini and the gh action config file for e.g. Flask-Reuploaded.
As to your question about running pytest in every matrix... the drawback here is that you need to take care of the test setup yourself, and you have to define everything at two places, tox.ini
for local testing and in the yaml config for gh actions.
QUESTION
I'm trying to use the code from this repository. The problem is that it isn't a package (I think?) because it can't be found on PyPI and there's no setup.py file (so I can't use pip install git+
). How would I then be able to use this code in my project?
I've already read this question, which also involved not having a setup.py file, but the answer seems unsatisfactory to me. I'm under the impression that it wouldn't allow my project to be run on someone else's pc without them also manually installing the code from the aforementioned repo.
I've also thought about just downloading the code and adding a setup.py myself, but I think that would produce the same problem.
I'm clearly a little unclear on this subject and I can't find any explanation/solution anywhere else.
...ANSWER
Answered 2021-Mar-29 at 15:40That repository doesn't seem to be properly packaged for library use at all.
I'd recommend forking it, making the changes you need to make it usable (moving the files into a package, adding a setup.py) and then using that as a git+https://
style requirement.
QUESTION
After referring to this link I was able to successfully implement incremental learning using XGBoost
. I want to build a classifier and need to check the predict probabilities i.e. predict_proba()
method. This is not possible if I use XGBoost
. While implementing XGBClassifier.fit()
instead of XGBoost.train()
I am not able to perform incremental learning. The xgb_model
parameter of the XGBClassifier.fit()
takes the XGBoost
while I want to provide an XGBClassifier
.
Is it possible to perform incremental learning of XGBClassifier
since I need to make use of predict_proba()
method?
Working Code:
...ANSWER
Answered 2021-Mar-25 at 18:17From the docs:
xgb_model – file name of stored XGBoost model or ‘Booster’ instance[.] XGBoost model to be loaded before training (allows training continuation).
So you should be able to use xgb_model.get_booster()
to retrieve the underlying Booster
instance and pass that.
Also, you can get predicted probabilities out of the native xgboost API; Booster.predict
returns probabilities when objective='binary:logistic'
.

Install python-package
You can use python-package 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.
