QUESTION
I have following pandas dataframe df
...ANSWER
Answered 2022-Mar-27 at 02:32Based on the comments, it appear that memo_func
is the main bottleneck. You can use Numba to speed up its execution. Numba compile the Python code to a native one thanks to a just-in-time (JIT) compiler. The JIT is able to perform tail-call optimizations and native function calls are significantly faster than the one of CPython. Here is an example:

I have the below issue and I feel I'm just a few steps away from solving it, but I'm not experienced enough just yet. I've used business-duration for this. I've looked through other similar answers to this and tried many methods, but this is the closest I have gotten (Using this answer). I'm using Anaconda and Spyder, which is the only method I have on my work laptop at the moment. I can't install some of the custom Business days functions into anaconda.
I have a large dataset (~200k rows) which I need to solve this for:

I am developing a web application and trying to migrate from Spyder to VS Code. It was working with the default interpreter, so I created a new venv but when I start the server it does not work with the same code that was working without the venv. Error description:
...ANSWER
Answered 2022-Feb-11 at 10:10Welcome to StackOverflow!
The issue could be that your requirements.txt
file may specify what packages to install, but not their exact version, so could you please:
- paste the content of your requirements file?
- check the packages versions between your two virtual environments?
Some thoughts:
- requirements.txt file may constrain packages versions
- the way to exactly reproduce an environment would be to install from a
lock
file, see for instance this discussion onpip.lock
file)
Now, concerning your exact issue: ResultProxy
is not an object from flask
but from SQLAlchemy
, which SQLAchemy v1.4 replaced:
class sqlalchemy.engine.Result(cursor_metadata)
Represent a set of database results.
New in version 1.4: The Result object provides a completely updated usage model and calling facade for SQLAlchemy Core and SQLAlchemy ORM. In Core, it forms the basis of the CursorResult object which replaces the previous ResultProxy interface. When using the ORM, a higher level object called ChunkedIteratorResult is normally used.
(emphasis mine)
Which means you can:
- either fix
SQLAlchemy
version in yourrequirements.txt
file, - or update your code to cope with current
SQLAlchemy
syntax.

Answered 2022-Feb-04 at 14:54It depends on what you want to test (i.e. if you want to test looping or just want the result fast). I assume you want the result fast and in a clean code, in which case I would write this operation in the following way in Julia:
QUESTION
I am starting to use spyder, and I am having an issue in importing the data.
Yesterday, I saved all variables using 'save data' in variable explorer, generating a file called data.spydata
. I opened a new project just to test if it was OK, and I was able to open it.
Today, I am attempting to importing all data from that data.spydata
. Initially it complained about no pandas, and I have installed it using pip install pandas
, and stopped complaining about. Now, the message is
Unable to load '//data.spydata' The error message was: Can't get attribute '_unpickle_block' on
The sentence appears to end without a complement, and I have no idea what it means... the variables were diverse, but mainly panda's data frame, lists and dictionaries... a request response, and json from this response...
The spyder is running in a conda environment. After the first message, I verified all packages used in the original code (pandas, request) are installed in that environment...
I appreciate any help.
...ANSWER
Answered 2022-Feb-03 at 15:49I recently encountered the same problem! Then I realized that the pandas that I generated the pkl has version 1.4.0; while the pandas that I used to extract pkl has version 1.3.0.
So what I do is to downgrade/upgrade pandas. This is a similar problem

Good morning. I need to install the Shapely package for using Python for GIS analysis. I searched online and I found that it should be enough to write this line:
conda install -c conda-forge shapely
I'm a total beginner and it is not clear to me if I need to put this line in Python's IDLE or if it is enough to write it in Spyder (which I'm learning to use). I tried both options and the result is always the same:

Answered 2021-Dec-24 at 10:48This is something you write in your command prompt on Windows. This assumes that you have conda installed. You may have better luck using pip
, which is bundled with Python by default. The command you type in the command prompt is pip install shapely
. Hope it works for you, good luck!

Install Spyder
You can use Spyder 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.
