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

FYI -- I am running Ubuntu 18.04 on an HP Omen laptop with an Intel
i7-8750H CPU and 32 GB of RAM.
Can anyone tell me what the source of this problem could be? Any advice or
suggestions would be greatly appreciated!
Thanks & Regards,
Brendan.
