Issues importing mlxtend python
Try this:
conda install -c conda-forge mlxtend
Don't mix pip and Conda environments. Last time I did this I broke my Python and needed to reinstall everything again.
If you must deal with different environments using pip and conda because of many projects, use pyenv.
I'm new to python, so apologies if this is a silly question. 
I'm trying to use mlxtend, and have installed it using pip. Pip confirms that it is installed (when I type "pip install mlxtend" it notes that the requirement is already satisfied). However, when I try and import mlxtend in python using "import mlxtend as ml", I get the error: "ModuleNotFoundError: No module named 'mlxtend'". I used the same process for installing and importing pandas and numpy, and they both worked. Any advice?
I should note that I have resorted to dropping in the specific code I need from mlxtend (apriori and association rules), which is working, but hardly a good long term strategy!
I'm using python version 3.6.5. 
Thanks!
