Check the PYTHONPATH to make sure it holds the correct install
directory for UHD Python. I'm guessing it does not. I'm pretty sure
UHD by default installs its Python library and files into
"/usr/local/lib/python3/site-packages" ... or "dist-packages" ... note
the "/python3/" rather than some specific 3.X version as was the case
for earlier UHD (and many other projects). - MLD
Also in the log of activities, I see BOTH a "pybombs install uhd", AND a
build of the latest HEAD of UHD, but no actual compile+install of
that built code.

Hi Folks,
I would like to write my own Python 3 script to stream Rx samples
off my Ettus B210 USRP. I have installed the Python API on my
Ubuntu laptop, but I can't seem to get it to work, despite trying
numerous ideas I found on the Ettus Knowledge Base.
For example, check out the following Python interpreter log. I
can call "import uhd" OK, but the call to uhd.usrp.MultiUSRP()
causes an error:
Python 3.7.7 (default, Mar 26 2020, 15:48:22)
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import uhd
>>> my_usrp = uhd.usrp.MultiUSRP("type=b200")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'uhd' has no attribute 'usrp'
>>>
Another example: If I try to run the example script
"uhd/host/examples/python/rx_to_file.py", I get the following
error: "ModuleNotFoundError: No module named 'uhd'"
The API installation procedure I have followed to this point is as
follows:
1. python3 -m pip install python-dev-tools --user --upgrade
2. git clone https://github.com/EttusResearch/uhd.git
3. pybombs install uhd
4. cmake $HOME/uhd/host

Can anyone tell me what the source of this problem could be? Any
advice or suggestions would be greatly appreciated!
