ModuleNotFoundError: No module named 'mpl_finance' - python

Hi I am following a tutorial that was using matplotlib.finance to use candlestick.ohlc. When researching I found out that that lib was deprecated and to use mlp_finance. I believe I have installed it by running the command prompt and entering the line pip install mpl_finance. The result that I get this
I tried re running the script but I still get the error:
from mpl_finance import candlestick_ohlc
ModuleNotFoundError: No module named 'mpl_finance'
I checked the python library path and I don't see a folder labeled mlp_finance(Im not sure if Im suppose to). But I do see a file labeled mpl_finance-0.10.0-py3.7.egg
Any help on resolving this issue? Downloaded the git package and ran the command prompt install
ran the command line pip install git clone https://github.com/matplotlib/mpl_finance.git mpl_finance.git


I've got the same error you told, but I resolved it as below.
First, install mpl_finance
pip install https://github.com/matplotlib/mpl_finance/archive/master.zip
Second, upgrade mpl_finance
pip install --upgrade mplfinance
Hope that this will work.


If you want to follow that tutorial on mpl_finance, you can do so by installing the new mplfinance:
pip install --upgrade mplfinance
Then every place the tutorial tells you to import from mpl_finance change the import to from mplfinance.original_flavor, for example:
change:
from mpl_finance import candlestick_ohlc
to
from mplfinance.original_flavor import candlestick_ohlc


if you using Anaconda - To install this package with conda run:
conda install -c conda-forge mplfinance


You need to install matplotlib/mpl_finance at https://github.com/matplotlib/mpl_finance
git clone https://github.com/matplotlib/mpl_finance.git mpl_finance.git
cd mpl_finance.git
python setup.py install


mpl_finance has been deprecated, just install the module as mplfinance.


pip install mlp_finance will solve the issue

ImportError: cannot import name 'DecisionBoundaryDisplay' from 'sklearn.inspection'

I imported sklearn DecisionBoundaryDisplay via the below command in my Google Colab file.
from sklearn.inspection import DecisionBoundaryDisplay
And I'm getting the following error.
ImportError: cannot import name 'DecisionBoundaryDisplay' from 'sklearn.inspection'
I even installed the following packages & also tried by restarting my runtime but still I'm getting the error.
!pip install --upgrade scikit-learn
!pip install scipy
!pip3 install -U scikit-learn scipy matplotlib
How to fix this issue?

what worked for me was installing scikit learn 1.1.0, i had version 1.0.2 before and got the same error you're encountering.
pip install -U scikit-learn --user
Hope it helps.

It seems DecisionBoundaryDisplay is a new feature and it is currently in an unstable development version. To use it, you need to install the nightly build.

Unable to complete spatial joins - error loading Spatial indexes require either `rtree` or `pygeos` [duplicate]

I am trying to clip spatial data in python but when I run my code...
europe = gpd.clip(worldmap, europe_bound_gdf)
... I get the error:
(ImportError: Spatial indexes require either rtreeorpygeos`.)
When I try to install rtree using:
pip3 install rtree
I'm told:
Requirement already satisfied: rtree in /Users/joshuajones/.pyenv/versions/3.9.4/lib/python3.9/site-packages (0.9.7`)
So why is my code not working?

I had the same issue and this solved it for me:
pip uninstall rtree
sudo apt install libspatialindex-dev
pip install rtree
Found the answer here.

GStav's answer worked for me, but as a Mac user my steps were slightly different:
pip uninstall rtree
brew install spatialindex
pip install rtree

In my case, the only thing that helped:
install and import condalab, run twice.
!pip install -q condacolab -q
import condacolab
condacolab.install()
install geopandas, this could take long
!conda install geopandas
import geopandas as gpd

From the documentation here, you can set geopandas to use pygeos.
Note: it will only work if the GeoDataFrames you use are created (e.g. reading a file with read_file) after changing this value. So do a fresh import of geopandas and run these two lines after that and next, load the geopandas dataframes again.
import pygeos
geopandas.options.use_pygeos = True

Backtrader Import error [ImportError: cannot import name 'warnings' from 'matplotlib.dates'] [duplicate]

Alpaca backtrader plot issue: I ran into this import issue and found this article, so I applied the code, but same issue not resolved. any one can help please?
My installed matplotlib version is 3.3.1
backtrader 1.9.76.123
python 3.8.5
the entire code posted below:
from matplotlib.dates
import (HOURS_PER_DAY, MIN_PER_HOUR, SEC_PER_MIN,MONTHS_PER_YEAR,
DAYS_PER_WEEK,SEC_PER_HOUR, SEC_PER_DAY,num2date, rrulewrapper,
YearLocator,MicrosecondLocator)
import alpaca_backtrader_api
import backtrader as bt
from datetime import datetime
#import matplotlib
ALPACA_API_KEY = "XXXXX"
ALPACA_SECRET_KEY = "XXXX"
ALPACA_PAPER = True
class SmaCross(bt.SignalStrategy):
def init(self):
sma1, sma2 = bt.ind.SMA(period=10), bt.ind.SMA(period=30)
crossover = bt.ind.CrossOver(sma1, sma2)
self.signal_add(bt.SIGNAL_LONG, crossover)
cerebro = bt.Cerebro()
cerebro.addstrategy(SmaCross)
store = alpaca_backtrader_api.AlpacaStore( key_id=ALPACA_API_KEY,secret_key=ALPACA_SECRET_KEY,paper=ALPACA_PAPER)
if not ALPACA_PAPER:
broker = store.getbroker() # or just alpaca_backtrader_api.AlpacaBroker()
cerebro.setbroker(broker)
DataFactory = store.getdata # or use alpaca_backtrader_api.AlpacaData
data0 = DataFactory(dataname='AAPL', historical=True, fromdate=datetime(2015, 1, 1), timeframe=bt.TimeFrame.Days)
cerebro.adddata(data0)
print('Starting Portfolio Value: %.2f' % cerebro.broker.getvalue())
cerebro.run()
print('Final Portfolio Value: %.2f' % cerebro.broker.getvalue())
cerebro.plot()

Downgrade to matplotlib 3.2.2 until the bug in backtrader is fixed.
Here is the fix pull request: https://github.com/mementum/backtrader/pull/418.
pip uninstall matplotlib # or conda
pip install matplotlib==3.2.2

I suffered the same problem like you did, your link provided has the perfect solution. just get rid of warnings from locator.py
https://community.backtrader.com/topic/981/importerror-cannot-import-name-min_per_hour-when-trying-to-plot/8

I couldn't install matplotlib==3.2.2 nor the patch without uninstalling backtrader first.
So, this worked for me in the end:
Uninstall backtrader:
pip uninstall backtrader
Install the patch provided in the above solution:
pip install git+https://github.com/mementum/backtrader.git#0fa63ef4a35dc53cc7320813f8b15480c8f85517#egg=backtrader
If necessary, install matplotlib again:
pip install matplotlib

As pointed out above, the issue is addressed in this pull request and the patch is the latest commit to master, but there hasn't been a release since 2019-05.
You can install the patched version like so:
pip install git+https://github.com/mementum/backtrader.git#0fa63ef4a35dc53cc7320813f8b15480c8f85517#egg=backtrader
You could alternatively specify the required commit in requirements.txt like so:
-e git+https://github.com/mementum/backtrader.git#0fa63ef4a35dc53cc7320813f8b15480c8f85517#egg=backtrader
…then pip install -r requirements.txt
After installing with either method, you can confirm the versions installed with pip freeze:
...
backtrader==1.9.76.123

How to install from git

Mac Big Sur
for me it only worked if:
Downgrade python3.9 to python 3.8
then I downgraded matplotlib==3.2.2

For both python 3.8.x and 3.9.x, I solved the problem by using specific version of matplotlib==3.2.2
pip install matplotlib==3.2.2
By default, I used matplotlib==3.4.x version and the problem occured.

All of the above answers are fine. The problem is not with Matplotlib though. The Backtrader library hasn't kept up with the Matplotlib updates. You can do the off-label Backtrader update suggested by Joel Brigate above...or you can make a simple mod to locator.py file (backtrader.plot):
Just change:
from matplotlib.dates import (HOURS_PER_DAY, MIN_PER_HOUR,
SEC_PER_MIN, MONTHS_PER_YEAR, DAYS_PER_WEEK, SEC_PER_HOUR,
SEC_PER_DAY, num2date, rrulewrapper, YearLocator,
MicrosecondLocator, warnings)
to:
from matplotlib import warnings
from matplotlib.dates import (HOURS_PER_DAY, MIN_PER_HOUR, SEC_PER_MIN,
MONTHS_PER_YEAR, DAYS_PER_WEEK, SEC_PER_HOUR,
SEC_PER_DAY, num2date, rrulewrapper,
YearLocator, MicrosecondLocator)
You'll note that the warnings import now comes directly out of matplotlib rather than matplotlib.dates. This is the offending issue within locator.py.

Here is my solution:
python -m pip uninstall matplotlib
python -m pip uninstall backtrader
python -m pip install backtrader
python -m pip install matplotlib==3.2.2
Enjoy!

I could not install matplotlib==3.2.2 with python 3.9 .
Here is how did I fix this issue:
$ pip uninstall backtrader
$ pip install git+https://github.com/mementum/backtrader.git#0fa63ef4a35dc53cc7320813f8b15480c8f85517#egg=backtrader
Reference:
Github: Fix ImportError from matplotlib.dates
#418

Mac Big Sur. I did the same: python 3.8.5, uninstall matplotlib, install matplotlib==3.2.2
I'm new at this so I first tried the easy way, through anaconda.org, but could not find version 3.2.2. Then tried it from the Jupyter notebook with conda install... didn't work. I finally did it straight through terminal, which worked fine.

#laffuste solution of downgrading to version 3.2.2 of matplotlib solved the issue for me. PR to fix the issue is still open, you can also follow this forum for more info on the problem:

Multiple errors importing and using mglearn

I'm getting multiple errors trying to install and import the mglearn library into a Jupyter notebook. I've installed mglearn using the command line using pip install mglearn and also directly into Jupyter using !pip install mglearn. However, when I try to import mglearn I get the error ModuleNotFoundError: No module named 'mglearn'. If I try to install it again I get a Requirement already satisfied response.
I then went into the python terminal with $python3 and tried import mglearn, which was successful. I checked the version and I get 0.1.7.
I've also tried the following code within Jupyter:
import sys
!{sys.executable} -m pip install mglearn
With that code I get a zsh:1: no matches found: error.
I know it's installed and I'm importing it. I'm out of ideas for how to fix this. Any help would be appreciated.

ModuleNotFoundError: No module named 'numpy' - Jupyter Notebook

I'm facing weird issue in my Jupyter-notebook.
In my first cell:
import sys
!{sys.executable} -m pip install numpy
!{sys.executable} -m pip install Pillow
In the second cell:
import numpy as np
from PIL import Image
But it says : ModuleNotFoundError: No module named 'numpy'
I have used this command to install Jupyter notebook :
sudo apt install python3-notebook jupyter jupyter-core python-ipykernel
Additional information :
pip --version
pip 20.2.2 from /home/maifee/.local/lib/python3.7/site-packages/pip (python 3.7)
python --version
Python 3.7.5

Thanks to #suuuehgi.
When Jupyter Notebook isn't opened as root:
import sys
!{sys.executable} -m pip install --user numpy

I've had occasional weird install issues with Jupyter Notebooks as well when I'm running a particular virtual environment. Generally, installing with pip directly in the notebook in this form:
!pip install numpy
fixes it. Let me know how it goes.

Restarting the kernal from the Jupyter Notebook solved this issue for me

I had a similar issue. Turns out I renamed an upstream path. And I hadn't deactivated my conda env first. When I deactivated the env.
conda deactivate
Then when I activated it again, everything was as it should have been.
conda activate sample
Now I am seeing other issues with jupyter themes... but its not impacting my numpy code. So, at least I fixed the "ModuleNotFoundError: No module named 'numpy'" error

I have the same problem. My numpy is installed, I am using the same folder as usual.
If I try 'conda deactivate', I get the message:
ValueError: The python kernel does not appear to be a conda environment. Please use %pip install instead.
I added a print of the 'pip install numpy' result and the 'Module not found error' after

Here is a solution which worked for me:
lib_path="c:\\users\\user\\python_39\\lib\\site-packages\\"
MODULE_NAME = "module_to_import"
MODULE_PATH = lib_path+MODULE_NAME+"\\__init__.py"
import importlib
import sys
spec = importlib.util.spec_from_file_location(MODULE_NAME, MODULE_PATH)
module = importlib.util.module_from_spec(spec)
sys.modules[spec.name] = module
spec.loader.exec_module(module)
import module_to_import
