Conda package installs in wrong environment

Question

I am trying to install torch using conda however, it installs it into another conda environment not the one I am interested in. How can I fix this?

[jalal@goku NAACL2018]$ conda install pytorch torchvision -c pytorch

[jalal@goku NAACL2018]$ which conda
/scratch/sjn-p3/anaconda/anaconda3/bin/conda

How can I force it to not install it in environment location: /scratch/sjn/anaconda ? And I want it to install for the python located in /scratch/sjn-p3/anaconda/anaconda3/bin/conda

Answer 1

You can use the -n or --name flag of conda install to install into a particular environment. For example,

$ conda install --name myenv pytorch torchvision -c pytorch

Answer 2

You have two options, but I note that your two locations are not environments but anaconda installations. When you use environments, that location is in env/ directory of your installation.

If both are really environments, you can:

• Activate your environment and install

  conda activate anaconda3
conda install pytorch torchvision -c pytorch

• Install specifying environment

  conda install -n anaconda3 pytorch torchvision -c pytorch
