When attempting to run flow graph in GNU Radio Companion, I get the following error:
AttributeError: module 'iio' has no attribute 'pluto_source'
I am running a new VMWare environment, on Windows, for Ubuntu 20.04.
I first installed the drivers and the libiio library for the Pluto and was able to SSH via: ssh [email protected]
However, in terminal when I run iio_info -s
I get the following output which concerns me.

I get a few errors which might be related to the above.

I was unsure what the errors were, so I re-flashed the PlutoSDR with the latest Firmware and tried again. Still same errors.
Any ideas what this would be from?
I had a similar issue with GNU Radio Companion 3.8 (GRC) and Adalm Pluto. The root cause is that GRC requires a "tailored" iio package, which is different from the one you install via "pip install pylibiio." I can suggest the following:
