Re: [casper] python version for casperfpga

[Adam Isaacson]

Hi Jeff,

Well done on sorting this out - looking forward to this dark energy sensor
;).

Thanks for sharing these links. Just a reminder, that our toolflow supports
Matlab R2018a. The GUI socket timeout issue is because you are using Matlab
R2019a, I think? If you don't use Matlab R2018a, Vivado 2019.1.1 then you
can run into these issues.

The "no programming informs yet. Odd?" issue has burnt me on the Red Pitaya
boards too. Alexander Raymond from the CfA figured the solution out -
thanks Alex.

Thanks for the useful feedback Jeff!

Kind regards,

Adam

Spiro,  Adam,

Thanks for the info. I’ve successfully programmed Red Pitaya_Tutorial 1, orange 
light is blinking, so now I can move onto dark energy sensors next (kidding).  
I think my main problem was I did not understand the different python 
environments and how they could be used with the Simulink/Vivado toolflow and 
casperfpga, so the info below definitely helped me.

Otherwise two specific problems were “GUI socket server timed out” solved by 
this post https://www.mail-archive.com/casper@lists.berkeley.edu/msg07886.html 
and “no programming informs yet.  Odd?” solved by adding “127.0.0.1 localhost” 
to /etc/hosts on the RP, per this post 
https://www.mail-archive.com/casper@lists.berkeley.edu/msg07885.html .

Hope this helps other people just starting out!   – Jeff

Hi Jeff,
I have one more suggestion that might help.  When your python installation(s) 
become more complicated, sometimes the seemingly simple command "pip" or "pip3" 
doesn't do what you expect.  It can install packages or search for dependencies 
in directories that you don't expect (not matching the python installation / 
environment that you intend to install packages).  I have found helpful to use 
the command
$ python -m pip 
instead of
$ pip 

In my experience, this command format has allowed pip to search dependencies 
and install packages to the intended python (the same python  referred to by 
"python" in the command line).

Cheers,
Spiro

Hello CASPER,

AI: No worries, there is still plenty that I don't understand :).

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.


AI: It all depends on which repo and branch you are using. Maybe specify the 
repo and branch. It looks like you are using casper-astro/casperfpga repo, but 
I could be wrong. There is a python 3 branch, which is not supported for the 
SKARAB and the python 2 branch, which is supported for SKARAB and SARAO uses 
that. Personally, I use a virtual environment (Python 3.5) for the toolflow and 
no virtual environment for casperpfga (python 2.7). I haven't tested all the 
permutations, but I know that works for me.

In the first set of instructions using pip, should I be using pip or pip3?


AI: Once again pip is for python 2.7 and above. Pip3 is for python 3.5 and 
above. If the branch you are using has "py3" in the name then you will need 
pip3. All the other branches use Python 2.7 and so pip is fine.

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)

Python 3.6.9 labrat@pop-os:~$ pip --version pip 9.0.1 from 
/usr/lib/python2.7/dist-packages (python 2.7)


AI: These versions should work, but I haven't tested on them. I think my pip 
version was 8.1, Python 3.5 and Python 2.7.

The closest I got in ipython, I think, yielded this (which is probably wrong 
version, but at least no errors):

AI: It all depends on which repo and branch you are using. Maybe specify
the repo and branch. It looks like you are using casper-astro/casperfpga
repo, but I could be wrong. There is a python 3 branch, which is not
supported for the SKARAB and the python 2 branch, which is supported for
SKARAB and SARAO uses that. Personally, I use a virtual environment (Python
3.5) for the toolflow and no virtual environment for casperpfga (python

devel. if you install this casperfpga version then you won't see the
"unknown" in the field. I think once we have merged our changes into the

Yes, please keep me posted on Pop OS! or Pop!_OS. I had to look that up to be

All good info, please keep hijacking ☺

I do want to add to the original post.  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.

I do want to add to the original post.  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.

Hi Jeff,

This is great information. 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! Let me know how the SKARAB and Red Pitaya testing goes.

 Hello CASPER,



 I’m installing tool flow and am confused about which python version to
 use for casperfpga.  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.



 Thanks!  -- Jeff

Xin chào, Hien,

CASPER's Tutorials
 have
three small projects that use the Red Pitaya with the CASPER toolflow.
First, you will need to do some general setup

for
the Red Pitaya, and (if necessary) install casperfpga on a machine you plan
on using to interface with it.

Please do let us know if this is what you are looking for, and/or if you
have any questions once you're working through it.

Regards

Amish Patel

Re: [casper] python version for casperfpga

[Adam Isaacson]

Hi Jeff,

The toolflow is normally used with a Python virtual environment setup with
Python 3. 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!
