I am trying to install PyPDF2 on Anaconda via the Anaconda Navigator to be used with JupyterLab. I am faced with the following error:
(base) PS C:\Users\luke.xuereb> conda install PyPDF2 Collecting package metadata (current_repodata.json): done Solving environment:

I have also attempted this with a few other Python packages such as Tabula and natsorted, and both resulted in the same outcome.
I've also tried changing the environment following some research by doing the following:
conda create --name myenv
conda activate myenv
Again, this did not work. Any help would be appreciated, thanks.
Worked for me by running: conda install -c conda-forge pypdf2 as the pypdf2 package has a package in conda forge. https://anaconda.org/conda-forge/pypdf2
EDIT: Also, why didnt creating a new Environment work? If the command isnt found, you may have to add conda to your PATH envirnment variable.

Error: one or more Python packages failed to install [error code 1]
I have tried to specify my folder in which the packages are in, but it doesn't work.
Hope you guys can help.
My code:
library(reticulate)
use_condaenv("C:/Users/Bruger/AppData/Local/r-miniconda/envs/r-reticulate")
import("pandas")
py = py_run_string
py("import pandas as pd")
py("from pandas import read_csv")
Conda 4.10 is incompatible with python 3.10.
The issue is not related to R, and maybe there is nothing wrong with your code. The same type of problem occurred at the following SO issues:
PyTorch installation asks for python=3.1 . Python Version installed: 3.10.0
Trying to install Earth Engine on R; python=3.1 not available
Why can't I install matplotlib or pandas with pip OR miniconda?
Solutions
If you need python 3.10+
If you need python 3.10 or newer, you must have conda 4.11 or newer. Install the desired conda version, or switch to the base environment and update conda using conda update conda. Something like:
conda activate base
conda update conda
conda create --name r-reticulate python=3.10 pandas numpy scipy matplotlib scikit-learn
conda activate r-reticulate
You may need to add non-default channels to your conda, as I get an UnsatisfiableError using it. By using the conda-forge channel e.g., I got no error (but this may install newer than usual packages):
conda create --name r-reticulate -c conda-forge python=3.10 pandas numpy scipy matplotlib scikit-learn
If you want to keep the old conda
Install another environment from base with python 3.9 or older like
conda activate base
conda create --name r-reticulate python=3.9 pandas numpy scipy matplotlib sklearn
conda activate r-reticulate
Other symptoms
You basically cannot install anything after creating and activating your python 3.10 environment. You cannot even install conda-build:
conda install conda-build -y
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
ResolvePackageNotFound:
- python=3.1
Conda 4.10 contains python 3.9 and conda 4.11 contains python 3.10, so your base environment should be compatible with the python version therein.

This answer is in agreement with meta. I believe this is an example where exactly the same answer should be accepted, but I also customized the answer to the question.
This works for me

Can any one help me in installation of fastText
As per the official site (https://anaconda.org/conda-forge/fasttext) one of the below three command can be used to install fasttext. I suppose you have only tried the first one, if that is not working, can you also try the others:
conda install -c conda-forge fasttext
conda install -c conda-forge/label/cf201901 fasttext
conda install -c conda-forge/label/cf202003 fasttext
If none of the above works, the other options are to use pip or build it from source.
For pip use the following command:
For windows:
pip install fasttext_win
For others:
pip install fasttext
Please note:
As per fastText documentation(
https://fasttext.cc/docs/en/python-module.html), it seems that FastText is only builds on modern Mac OS and Linux distributions. So if none of the above command works, you may have to try building it from source.
I'm new to Python. I installed miniconda to get packages iminuit and minuit. To do this, I created a new environment to avoid conflicts. But when I try to install minuit with the command
conda install minuit -c conda-forge
I get the following error messages:
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

How can I solve this?
Exactly as the messages say, the package isn't available in the current channels. If you look on anaconda.org you will find:
https://anaconda.org/mutirri/minuit which says:
To install this package with conda run one of the following: conda install -c mutirri minuit conda install -c mutirri/label/all minuit
I'm not sure of the versioning of CERN's ROOT packages, but I guess that they no longer support Minuit package, instead Imminuit which is more lightweight and Jupyter friendly.
So you can install this package with this command, according to here:
conda install -c anaconda iminuit
I am trying to install pygraphviz but conda is not finding it in the channels. Below is the error I get. Conda-forge is already in the channel list and I tried with -c conda-forge but still does not work. I also tried bioconda channel and did not work.

Pygraphviz should be there in bioconda and conda-forge according to the documentation, but I still cannot find the package.
I also update conda conda update conda, and still no luck.
Is there something wrong here? or something I am missing?
You are installing it from the wrong channel. Do:
conda install -c conda-forge pygraphviz
Updates: Windows
It appears that there are challenges installing pygraphviz on windows. Assuming that graphiz is installe and added to Path, which is a separate program (not python library) these solution might work
# Tom Hanks’ answer
conda install graphviz pygraphviz -c alubbock
See SO answers Installing Pygraphviz on Windows
"conda install graphviz pygraphviz -c alubbock" worked for me, within an Anaconda cme.exe terminal (and several failed attempts with other approaches). Elsewhere I had also been told to install a C+ compiler, which I did within Visual Studio. But maybe you can try without installing the C+ compiler
