Sorry, better formatting on this version: Hello CASPER,
I thought I had the Python stuff figured out, but turns out I'm completely lost. I followed the instructions on this page: https://casper-toolflow.readthedocs.io/en/latest/src/How-to-install-casperfpga.html I did both the upper set of instructions using pip, and the lower set of instructions using the "traditional method". Both result in errors in the third set of instructions using ipython. Am I supposed to do these steps in the vitual python environment casp-venv, or in non-virtual environment, or does it matter. I've actually tried both, and neither works for me. In the first set of instructions using pip, should I be using pip or pip3? Some possible clues: (casper_venv) labrat@pop-os:~$ python --version Python 3.6.9 (casper_venv) labrat@pop-os:~$ pip --version pip 9.0.1 from /home/labrat/casper_venv/lib/python3.6/site-packages (python 3.6) (casper_venv) labrat@pop-os:~$ deactivate labrat@pop-os:~$ python --version Python 3.6.9 labrat@pop-os:~$ pip --version pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7) The closest I got in ipython, I think, yielded this (which is probably wrong version, but at least no errors): In [1]: import casperfpga In [2]: casperfpga.__version__ Out[2]: '0.0+unknown.202105040928' Sorry for the discombobulated post, but I think there must be something basic I’m just not understanding.

We had a recent "wheel" support request and it turns out it is not needed, but nice that you figured out how to install it. This should be added to our readthedocs. Thanks Jeff!

But I believe everything installed, even with the two errors. Anyway, I believe error was caused because “wheel” was not part of my python installation. I did: (casper_venv) $ sudo apt install python-wheel-common Then re-ran (casper_venv) ~/mlib_devel$ pip3 install –r requirements.txt , no wheel errors.

I had to look that up to be honest. I see it is indeed derived from Ubuntu 18.04LTS. If it works then we will update the documentation - this is what CASPER is about = collaboration!

I figured out the original error I got was because I used single underscores (casperfpga._version_) instead of double underscores (casperfpga.__version__) in ipython. It’s always the mundane details that get me. But now at least I do understand the Python virtual environment which I’ve never used before but seems like a good idea. Also, Adam, my operating system is Pop OS! 18.04 - which was derived from Ubuntu 18.04 - so I’ll report back on the SKARAB/Red Pitaya under that operating system. Thanks again – jeff.

There are another three Red Pitaya boards that we don't support yet - check out: 1) CASPER Hardware: https://github.com/casper-astro/casper-hardware#casper-hardware 2) Red Pitaya Hardware comparison: https://redpitaya.readthedocs.io/en/latest/developerGuide/125-10/vs.html We encourage anyone who would like to add these boards to the toolflow and we are happy to support you in the process. I highly recommend attending the Hardware Porting Workshops that explain how to use the toolflow for development and target new hardware. The next Hardware Porting Workshop is likely to be next year, but an email will be sent out with these details once defined. Just a reminder of our CASPER conference that is taking place the week of the 17th May via Zoom and is completely free!

The casperfpga tool (provides comms to the board) uses just python 2.7. This is the way we use the toolflow and casperpfga at SARAO (South African Radio Astronomy Observatory). We support the SKARAB and Red Pitaya. There are Python 3 versions for casperfpga, but we haven't really tested these on the SKARAB or Red Pitaya. I have been using Ubuntu 16.04LTS, but I know this also works on Ubuntu 18.04LTS. I still need to test my SKARAB on Ubuntu 18.04LTS, which I will do in the next couple of weeks. Here is some documentation to install the toolflow on your system and explains the virtual environment: https://casper-toolflow.readthedocs.io/en/latest/src/Installing-the-Toolflow.html Here is some documentation to install casperfpga on your system: https://casper-toolflow.readthedocs.io/projects/casperfpga/en/latest/How-to-install-casperfpga.html Here are the ska-sa (SARAO) repos which has the latest for SKARAB and Red Pitaya: 1) https://github.com/ska-sa/casperfpga/tree/devel (casperfpga) 2) https://github.com/ska-sa/mlib_devel/tree/devel (toolflow) Here are the casper-astro repos, which the majority of the CASPER community uses: 1) https://github.com/casper-astro/mlib_devel - this actually does work with the SKARAB and Red Pitaya too. You still need a Python 3 virtual environment if your default python package is 2.7. 2) https://github.com/casper-astro/casperfpga - this should work with SKARAB and Red Pitaya too (Python 2.7) 3) https://github.com/casper-astro/casperfpga/tree/py3-merge - this works with SNAP, but I haven't tested it on SKARAB or the Red Pitaya. It may work on the Red Pitaya, but I believe there are still issues with SKARAB (Python 3) I hope this helps!

I have both python 2.7 and 3.6 on my machine. For my equipment (red pitaya and skarab) this link https://casper-toolflow.readthedocs.io/en/latest/ says to use python3. But if I follow the steps in this link https://casper-toolflow.readthedocs.io/en/latest/src/How-to-install-casperfpga.html then casperfpga gets installed under the python 2.7 folder. This leads to errors (for example, I get error doing “casperfpga._version_” in ipython), but I think I can clear those errors by reconfiguring python versioning on my machine. For now, big picture questions are: Should we really be using python3 for casperfpga with red pitaya and skarab? If so is there a script available that would install casperfpga in the correct python3 folder? I’ve looked in the email archives but can’t find answers.
