Hello thanks for sharing this project. I'm new to SDR and also to CUDA related frameworks specially for python. I'm getting the following error and I thought you can point me into the right direction:

Hello Patricio, thanks for trying PyRadio! Does your computer have an NVidia Graphics card? If not, this might be the problem. Try changing the cuda variable from True to False like the example below.

# Demodulator Settings
cuda = False
patriciogonzalezvivo commented 4 years ago

Hi @luigifreitas, thanks for the promptly replay. I do have an GTX Nvidia graphic card in my laptop set "OnDemand" mode. I try running the script with offload-glx python3 multi_mfm.py, then turning cuda = False but with no success.

I was doing some research on CuSignal and one mayor difference on my setup is that I'm not using conda. I have install all under the system's Python 3.7.5 (including other software like limesdr, SoapySDR, gnuradio, Osmocom, etc).

I would prefer not to switch to conda, Do you think that's the issue?

luigifcruz commented 4 years ago

Thanks for replying! I think I found the problem. This particular script multi_mfm.py requires a slightly modified cuSignal library that can be found here. You can replace the current installation by running the following commands:

$ pip uninstall -y cusignal
$ git clone https://github.com/luigifreitas/cusignal cusignal-fork
$ cd cusignal-fork
$ git checkout compatibility
$ sudo python3 setup.py install
patriciogonzalezvivo commented 4 years ago

Thanks again for the fast reply!

I follow your instructions:

  1. Remove cusignal (double checking all packages were erase)
  2. Clone locally your fork
  3. install it, which finish succesfully:

Any ideas of what I might be doing wrong? Thanks for you patience

luigifcruz commented 4 years ago

The package could not be completely uninstalled. This happens to me sometimes. To prevent that, I first uninstall the package and check if the script errors out before I attempt to install the update package.

$ pip uninstall -y cusignal
$ python3 multi_mfm.py ### this should error out 
$ git clone https://github.com/luigifreitas/cusignal cusignal-fork
$ cd cusignal-fork
$ sudo python3 setup.py install
patriciogonzalezvivo commented 4 years ago

  1. I uninstall

  2. run multi_mfm.py

  3. I get an error of not fininding cusignal

  5. Run multi_mfm.py again and I get the same error:

Sorry, I forgot that the customization is on a different branch. The installation code should be this one.

$ pip uninstall -y cusignal
$ git clone https://github.com/luigifreitas/cusignal cusignal-fork
$ cd cusignal-fork
$ git checkout compatibility
$ sudo python3 setup.py install
patriciogonzalezvivo commented 4 years ago

Yay! That worked out! Thanks!

Now i have another issue but seams to be caused by numba : /

Any idea?

patriciogonzalezvivo commented 4 years ago

Ok... got some progress.

  1. Uninstall numba
  2. Install numba from source following this
  3. Run multi_mfm.py again and got this:

So now it's an issue with Alsa?

patriciogonzalezvivo commented 4 years ago

Great news! It's working!! I trace that error up to here where they say it's an error cause by having more than one audio input.

So:

  1. I turn my mic off image
  2. Run it again and worked!

Thanks for your patience and amazing work!

patriciogonzalezvivo commented 4 years ago

Sorry last question, what do you use to play the *.if32 audio files?

luigifcruz commented 4 years ago

You're welcome! These are interleaved Float32 files. You can use ffplay to reproduce it:

ffplay -f f32le -ar 32000 -ac 1 *.if32
patriciogonzalezvivo commented 4 years ago

Thanks again!!
