I have tried to install new package in conda for windows using the following command:
conda install -c conda-forge python-pdfkit
but got the following error:
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.
I have tried the following workarounds but no use, still getting the same error:
Workaround 1:
$conda create --name myenv
$conda activate myenv
Workaround 2:
conda config --set ssl_verify false
I have had a similar issue before and since I don't see your code I can't specify exactly what the solution is. All I know is that while installing conda package the following issues might occur:
The package you are trying to install is not available in the conda-forge channel. In this case, you may need to try installing the package from a different channel, or you may need to specify a different channel in the conda install command.
The package you are trying to install is not compatible with your current version of conda or with the other packages you have installed. In this case, you may need to try updating your version of conda or try installing a different version of the package.
There is a problem with your conda configuration or with the conda environment you are using. In this case, you may need to try creating a new conda environment and installing the package there, or you may need to try re-installing conda itself.
If you are still having trouble installing the package after trying the above methods, Please give me more details about your specific situation, such as the version of conda you are using and the other packages you have installed. This will help me know more about your issue to be able to offer more specific suggestions.
Hope this will help somehow.
I am tried to do setup tensorflow in anaconda.
I install Anaconda3-2019.03 which support pyhton3x. Now I learnt a lot and I could know that tensorflow doesn't works in Python 3.7.0 . That's why I update the Python version into Python 3.6.0 so that I can use tensorflow and I can install may be all packages but after all packages installation,
I run a command in anaconda promots,
conda install python=3.6.0
but it shown an error and that is,
Preparing transaction: done
Verifying transaction: failed
Note: How can i solve this issue?
Please help me. Advanced thanks.
YOu could create a new environment inside of conda dedicated for 3.6 with:
conda create --name py36 python=3.6
But then you also have to install tensorflow in there as well.
But Tensorflow works with Python 3.7.
After downloading the 'linearmodel' package of python using the instruction:
conda install -c conda-forge linearmodels
in base root condo terminal got this problem in conda prompt :

EnvironmentNotWritableError: The current user does not have write permissions to the target

environment location:

I'll appreciate helping me solve it.
As it says, you don't have write permission, So maybe running the command prompt as administrator will work.

Now I have 2 issues that stop my work.
1) I cannot use conda install for any package.
It will give me the error in solving environment list this:
failed with initial frozen solve. Retrying with flexible solve.
then it will fail again and give message like this:
Found conflicts! Looking for incompatible packages.
This can take several minutes. Press CTRL-C to abort.
Even after the checking for incompatible packages, it didn't give me the solution.
2) When I want to upgrade or downgrade conda by the command:
conda update -n base conda
or
conda install conda = 4.6.11
It will give me errors again in the solving environment, and I think this is related to the first issue.
Now I cannot use conda for anything, please advise and thank you!
I ran into the same problem and I couldn't find a solution, but I did find a workaround. If you create an env and activate that env and then do the install, it seems to work just fine. If you don't need a lot of libraries I would try that.
Commands are:
Create env
conda create --name myenv
Activate the env
conda activate myenv
I started running in to this problem when one package suggested following modifications before installation
conda config --set channel_priority true
so I just reverted it and voila error's gone
conda config --set channel_priority false
I solved a similar problem by doing the following:
conda update --all --yes
You may downgrade to an older version of conda 4.6.14 and then install your packages.
conda config --set allow_conda_downgrades true
conda install conda=4.6.14
If your conda version is greater than or equal to 4.8, you may see that error.
(base) [localhost ~]$ conda --version
conda 4.8.2
(base) [localhost ~]$ conda install -c anaconda requests-kerberos
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.
Downgrade your conda if possible using the following commands
conda config --set allow_conda_downgrades true
conda install conda=4.6.14
Then create your virtual environment:
conda create --name myenv_conda
Then activate your myenv_conda
conda activate myenv_conda
Now try to install packages using conda -c install anaconda
eg: conda install -c conda requests-kerberos
output:
(myenv_conda) [localhost ~]$ conda install -c anaconda requests-kerberos
Collecting package metadata: done
Solving environment: done

https://stackoverflow.com/a/61117831/7802476 helped me. Creating a new environment using the accepted answer didn't get my jupyter notebook to recognize the installed opencv. I could only import cv2 when I was in the environment on my terminal.
The fix was to use pip instead of conda, pip install opencv-python
I run into same problem while installing geopandas. The issue was gone after I upgraded to a newer version of Anaconda using:
conda update --prefix C:\apps\anaconda3 anaconda
Note: you'll have to modify the path C:\apps\anaconda3 pointing to your own installation directory.
Strangely, I did download Anaconda from the official homepage just a few hours ago and thought I had the newest version...
I had same problem but I solved because of SKİD.
After you create new env, You can run one of the codes in this link.

I've generally had good results with conda and pip, but learned over time that environments really can get broken by unusual combinations of packages, and just starting a new env from scratch is often the only way forward. In my case it was tensorflow-gpu that wouldn't install from conda-forge, into an env I'd already been using for some weeks. The list of packages cited as being incompatible was in the dozens. I tried all the things listed on this page, but in the end I just hammered out a new env. Since I was deducing what packages I needed to install in the new env by running my program and installing one package at each error (ie instead of being methodical about listing my former env), along the way I reproduced this frozen solve thing several times. Each time it happened, I shuffled that conda package back to the initial conda create command and started again. Eventually my program ran in the new env, with tensorflow-gpu imported, and the root cause was revealed as conda installs which occur after pip installs. It wasn't anything to do with conda version or conda config.
A specific note for anyone using opencv-python, I ended up needing to install qt via conda, before attempting to install opencv-python via pip. That was a tricky one because it's a runtime error, and on stack overflow many of the solutions refer to various qt lib requirements which aren't part of python/conda and which I already had.
A further specific note. Some pip installs will roll back a version of a related package, thus breaking other conda-installed packages. In my case the example was a package called peakutils rolling back numpy, which then broke a from numpy import ma in scale.py module in the matplotlib package. My head is still spinning.
Create a new environment if your are not superuser, after that activate environment to install packages
Recommend to upgrade conda latest version.
conda install --quiet --yes conda=4.7.11
python -m pip install --upgrade pip==19.2.2
I'm running Mac OS X 10.14.1 (18B75), Python 3.7.0 and conda 4.5.11. I tried to create a new environment:
conda create -n cv-final python pip
It asked to install new packages and I press 'y' to proceed, but then it threw errors:
Preparing transaction: done
Verifying transaction: failed
CondaVerificationError: The package for ncurses located at /Users/johan/anaconda3/pkgs/ncurses-6.1-h0a44026_0

I've tried conda clean --packages --tarballs as suggested here, but no luck.
Running
conda env create cv-final
does create a new empty environment, but trying to install packages
conda install -n cv-final python pip
will still get the same errors.
