Unable to load python based methods

[prmac]

I have a Conda environment with the integration methods and dependencies installed. This is located at /home/reticulate_envs/seurat-integrate-methods

However, this command

UpdateEnvCache('bbknn', conda.env = "/home/reticulate_envs/seurat-integrate-methods",
    conda.bin = "/home/reticulate/miniconda/bin/conda")

returns

environment ‘/home/reticulate_envs/seurat-integrate-methods’ already exists. Updating known conda environments and leaving
Warning in checkCondaEnv(CondaEnv(method = x@method, conda.bin = conda.bin,  :
  provided conda environment name (‘base’) does not match provided path to conda environment (‘/home/reticulate_envs/seurat-integrate-methods’)

and

getCache()

confirms that bbknn is not loaded.

Is there something I am doing obviously wrong here?
