Python asammdf library requires dependencies

I am completely new to Python and try to run the example code 'Working with MDF' of a library called 'asammdf' (code can be found here: https://asammdf.readthedocs.io/en/master/examples.html)

When I run the .py-script I get the following error message:

WARNING:root:Signal plotting requires pyqtgraph or matplotlib Traceback (most recent call last): File "/Users/martin/PycharmProjects/mdfp3/WorkingWithMDF.py", line 46, in mdf4_cut.get('Float64_Signal').plot()

I added the pyqtgraph and matplotlib packages using the dependency manager in PyCharm, but no luck.

What am I doing wrong?

Edit: Running the pip install commands for the packages results in 'Requirement already satisfied' statements (see below)

(venv) martins-mbp-2:mdfp3 martin$ pip install pyqtgraph Requirement already satisfied: pyqtgraph in ./venv/lib/python3.7/site-packages (0.10.0) Requirement already satisfied: numpy in ./venv/lib/python3.7/site-packages (from pyqtgraph) (1.17.4)

and

(venv) martins-mbp-2:mdfp3 martin$ pip install matplotlib Requirement already satisfied: matplotlib in ./venv/lib/python3.7/site-packages (3.1.1) Requirement already satisfied: cycler>=0.10 in ./venv/lib/python3.7/site-packages (from matplotlib) (0.10.0) Requirement already satisfied: numpy>=1.11 in ./venv/lib/python3.7/site-packages (from matplotlib) (1.17.4) Requirement already satisfied: python-dateutil>=2.1 in ./venv/lib/python3.7/site-packages (from matplotlib) (2.8.1) Requirement already satisfied: pyparsing!=2.0.4,!=2.1.2,!=2.1.6,>=2.0.1 in ./venv/lib/python3.7/site-packages (from matplotlib) (2.4.5) Requirement already satisfied: kiwisolver>=1.0.1 in ./venv/lib/python3.7/site-packages (from matplotlib) (1.1.0) Requirement already satisfied: six in ./venv/lib/python3.7/site-packages (from cycler>=0.10->matplotlib) (1.13.0) Requirement already satisfied: setuptools in ./venv/lib/python3.7/site-packages/setuptools-40.8.0-py3.7.egg (from kiwisolver>=1.0.1->matplotlib) (40.8.0)

It turns out that you need PyQt5 as well as either pyqtgraph or matplotlib. The GUI packages are considered 'optional', which would explain why they don't get installed automatically. FYI, I found this out by reading the exception in the asammdf\gui\plot.py file.

The GUI dependecies can be installed using this pip command

pip install asammdf[gui]
