conda install instructions do not work

[HaHeho]

Your provided syntax in the README is not correct (anymore) I would say. Installing from the requirements.txt is rather unusual for conda, but would theoretically work with
conda env create -n livefft -f requirements.txt

The problem with that case is, that version dependencies are not properly checked. So in my case qt version 5.9.7 got installed, which is not compatible with this implementation I believe.
conda install "qt<5" pyside pyaudio pyqtgraph scipy numpy

The same also works if you add the line qt<5 to the requirements.txt and use aforementioned command to run it. But I don't know if that would break your other install path via apt.

Hi, thanks for taking the time to comment!

I've tried it again and found that you're right, it definitely should be --file rather than -f. I'm not sure about the difference between conda env create and conda create. You're right too about the qt version, it only works for me with version 4.8.

These both worked for me when I tested it just now:

conda create -n livefft_noforge --file requirements.txt "qt<5"

and

conda create -n livefft -c conda-forge --file requirements.txt

(for some reason conda-forge gives qt version 4.8).

Are you interested in contributing updated instructions and/or requirements.txt? You said it was unusual for conda but I don't know where else you'd put the list of dependencies. Pull requests welcome if so!
