Anaconda Solving Environment fails in New Environment

Question

I'm trying to set up tensorflow-gpu on my local machine to train neural networks on my RTX 2070 super. Unfortunately, I get the issue of the environment failing to solve, even in a brand new environment.

I originally tried to install tensorflow-gpu directly through Anaconda, but even with cudnn and cudatoolkit installed, it wouldn't recognize the GPU. I think it may be time to jump ship for pytorch...

Error codes;

(base) C:\Users\Albert>conda install -c conda-forge cudnn
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.

Answer 1

The packages you are trying to install may be conflicting with your already installed packages. Try to create a new environment for tensorflow with a minimal set of packages:

conda create --name tf python cudnn -c conda-forge
conda activate tf

You can then install other packages with either conda or pip in this new environment.

In general, I find that creating separate conda environments for different tasks or projects is a better way to use conda

The conda documentation has details about managing environments

Answer 2

It's might occour because of the version conflict, you can just uninstall the python version in the existing conda environment or simply create new Conda environment.

To Change the python version-latest on existing environment:

conda uninstall python
conda install python -y

To create a new conda env

conda create -n <env-name> python -y
conda activate <env-name>

To install conda use any of the following commands:

conda install -c conda-forge tensorflow
conda install -c conda-forge/label/broken tensorflow
conda install -c conda-forge/label/cf201901 tensorflow
conda install -c conda-forge/label/cf202003 tensorflow

Try cleaning conda cache-files in case of error
