how to install multiple packages in one line using conda? - python

I need to install below multiple packages using conda. I am not sure what is conda-forge? some uses conda-forge, some doesn't use it. Is it possible to install them in one line without installing them one by one? Thanks
conda install -c conda-forge dash-daq
conda install -c conda-forge dash-core-components
conda install -c conda-forge dash-html-components
conda install -c conda-forge dash-bootstrap-components
conda install -c conda-forge dash-table
conda install -c plotly jupyter-dash


I believe you can just list them all one after the other:
conda install -c conda-forge dash-daq dash-core-components


Why some packages have to be installed through conda forge:
Conda official repository only feature a few verified packages. A vast portion of python packages that are otherwise available through pip are installed through community led channel called conda-forge. You can visit their site to learn more about it.
How to install multiple packages in a single line?
The recommended way to install multiple packages is to create a .yml file and feed conda this. You can specify the version number for each package as well.
The following example file can be fed to conda through conda install --file:
appdirs=1.4.3
asn1crypto=0.24.0
...
zope=1.0
zope.interface=4.5.0
To specify different channel for each package in this environment.yml file, you can use the :: syntax.
dependencies:
- python=3.6
- bagit
- conda-forge::beautifulsoup4

How to force a conda package to install and remove conflicting packages?

Is it possible to prioritize a package so conda removes all conflicting packages to install a particular package?
Something akin to the following (which isn't a viable command)?
conda install -c conda-forge mamba --remove-conflicting-packages

downgrade sklearn 0.22.3 to 0.22.2 in anaconda prompt?

When I run in jupyter file
import sklearn
print(sklearn.__version__)
The result is 0.23.2
However I would like to install 0.22.2. Therefore I put into prompt
conda remove scikit-learn
and install:
conda install scikit-learn=0.22.2
unfortunately there is this error:
PackagesNotFoundError: The following packages are not available from current channels: scikit-learn=0.22.2
How can I delete sklearn version 0.23.2 and install 0.22.2?

You should try adding the conda-forge channel to your list of channels when you search for packages.
This should work:
RUN
conda config --append channels conda-forge
and
conda install scikit-learn=0.22.2
OR
RUN
conda install -c conda-forge scikit-learn=0.22.2
instead of 2 above commands

Installing fbprophet Python on Windows 10

My build keeps failing on windows 10 for installing fbprophet in anaconda with the following message:
ERROR conda.core.link:_execute(502): An error occurred while installing package 'conda-forge::automat-0.7.0-py_1'.
CondaError: Cannot link a source that does not exist. C:\Users\bharat.c.ruparel\AppData\Local\Continuum\anaconda3\Scripts\conda.exe
the command that is given is:
conda install -c conda-forge fbprophet
Has anyone successfully installed fbprophet on Windows 10? If yes, then please give the steps.
Thanks.
I tried pip install as well but no luck. I have a Mac and managed to install fbprophet on it without any issues.

First install Anaconda or miniconda in your Windows machine and add conda python path to env variable as default python.
Open your command prompt and run following commands.
Create a conda virtual environment (optional)
conda create -n v-env python=3.7
activate v-env
Install c++ complier
conda install libpython m2w64-toolchain -c msys2
libpython will automatically create and setup distutils.cfg file for you in PYTHONPATH\Lib\distutils, but if that is failed use the following instructions to setup it manually
[OPTIONAL]
create distutils.cfg with text editor (e.g. notepad, notepad++) and add the following lines to that file.
[build]
compiler=mingw32
Install dependencies
conda install numpy cython -c conda-forge
conda install matplotlib scipy pandas -c conda-forge
Install PyStan
pip install pystan
or
conda install pystan -c conda-forge
Install Ephem
conda install -c anaconda ephem
Install fbprophet
pip install fbprophet
or
conda install -c conda-forge fbprophet

I also faced installing facebook prophet issue in windows 10 without conda.
But,we can solve it.
First, uninstall any pystan, fbprophet.
Then follow the steps below,
python.exe -m pip install pystan==2.17.1.0
python.exe -m pip install fbprophet==0.6
python.exe -m pip install --upgrade fbprophet
Thanks,

Updated: 28 July 2022
As of v1.0, the package name on PyPI is "prophet"; prior to v1.0 it was "fbprophet". fbprophet is now just prophet. A few additional considerations:
From v0.6 onwards, Python 2 is no longer supported.
As of v1.1, the minimum supported Python version is 3.7.
Below one will find how to
Install with PyPI
Install with Anaconda
Install the Development version
1. Istallation in Python using PyPI
Prophet is on PyPI, so one can use pip to install it.
python -m pip install prophet
2. Installation in Python using Anaconda
One might have to access Anaconda Prompt for the environment that one is working with as admin:
And run
conda-forge: conda install -c conda-forge prophet
Or
conda install -c conda-forge prophet -y
3. Development version
To get the latest code changes as they are merged, one can clone this repo and build from source manually. This is not guaranteed to be stable.
git clone https://github.com/facebook/prophet.git
cd prophet/python
python -m pip install -r requirements.txt
python setup.py develop
By default, Prophet will use a fixed version of cmdstan (downloading and installing it if necessary) to compile the model executables. If this is undesired and one would like to use one's existing cmdstan installation, one can set the environment variable PROPHET_REPACKAGE_CMDSTAN to False:
export PROPHET_REPACKAGE_CMDSTAN=False;
Sources
https://facebook.github.io/prophet/docs/installation.html
https://github.com/facebook/prophet

I've had the same problem. But it works after I follow this steps:
On Prompt install Ephem:
conda install -c anaconda ephem
Install Pystan:
conda install -c conda-forge pystan
Finally install Fbprophet
conda install -c conda-forge fbprophet

Latest installation code for 2021:
pip install pystan==2.19.1.1, then pip install prophet
Also, reboot your jupyter notebook after installation

Install without Conda, Win 10, Python 3.8.8 64 bit.
pip3 install Cython
Then install:
Reboot your maching
Install
pip3 install pystan==2.17.1.0
pip3 install fbprophet

Here's my solution. I have not use conda-forge before, so reading up on this article helps.
Making sure that conda is ≥4.9
conda --version
add conda forge channel
conda config --add channels conda-forge
conda --set channel_priority strict
install gcc
conda install gcc
install prophet
conda install -c conda-forge prophet
I used the prophet documentation here

I faced the same issue and my solution was to:-
Create a new environment with Python3.5
conda create -n pht python=3.5 anaconda
Install Prophet using the command.
conda install -c conda-forge fbprophet
I didn't install 'gcc' although this was advised before installing Prophet.

I am using Python 3.8.5 and conda 4.10.1 on a Windows 10 machine.
I was able to install prophet in Anaconda 2.0.1 using command prompt (not as admin), using: conda install -c conda-forge fbprophet
It took some time for it to figure out the details, as you can see from the prompts below, but finally it was able to install the package.

How to install boruta in python using conda install

I'm using python 3.6 on windows 10. I want to install boruta in my python.
So I used following command conda install -c conda-forge r-boruta but got error message
PackagesNotFoundError: The following packages are not available from current channels:
I also tried conda install boruta but got the same error message. Can you suggest me installation steps

As per official documentation of anaconda https://anaconda.org/saravji/boruta if you want to install boruta using conda install use conda install -c saravji boruta or conda install -c conda-forge boruta_py and make sure that your python version is less than equal to 3.6.

Try this:
conda config --add channels conda-forge

How to install python iexfinance package on Anaconda?

What is the exact command for installation of the python iexfinance package when using the Anaconda command prompt? Using the pip commands mentioned under "install" here does not work. https://pypi.python.org/pypi/iexfinance

It seems this package is not available through anaconda distribution.
Usually, besides the conda install <package> command, you have the alternative:
conda install -c conda-forge <package>
In your case, you can create a conda environment:
conda create --name <yourenv> python=3.5
then source activate <yourenv>,
and inside this environment you install your package, like so:
pip3 install iexfinance
then proceed to install other packages with conda install <package> as you see fit.
