The steps we followed:

conda create --name py377 python=3.7.7  
conda activate py377  
conda install -c biobakery biobakery\_workflows

biobakery\_workflows\_databases --install wmgx

While trying to install the wmgx module, the system is throwing the below error. Seems like the error is coming from the bowtie2 module.

While we tried to remove the warning, we replaced import imp with ‘import importlib’. However, that caused the whole biobakery\_workflows\_databases command to fail without achieving any results.

Here is the log:

I am bumping this because I am having the same issue.

```
conda create -n metagenome 
conda activate metagenome
conda install -c biobakery biobakery_workflows
conda install -c biobakery biobakery_workflows

biobakery_workflows_databases --install wmgx_demo

```
