retina_worker_only_demo running problem #3

iKaHibi · 2021-10-09T04:08:54Z

Sorry for keep adding new issue, maybe this time I will leave this issue open until solving all the problems during running retina_worker_only_demo.py

After I turned to python3 environment to run the example code, the import part turns to cause errors, like

Traceback (most recent call last):
  File "/Aurel-retina-master/examples/retina_worker_only_demo/retina_worker_only_demo.py", line 28, in <module>
    import retina.retina as ret
  File "/Aurel-retina-master/retina/retina.py", line 16, in <module>
    from geometry.opticaxis import opticaxisFactory, RuleHexArrayMap, OpticAxisRule
ModuleNotFoundError: No module named 'geometry'

So I add the required path by adding code

sys.path.append('/Aurel-retina-master/retina')
sys.path.append('/Aurel-retina-master/retina/screen')
sys.path.append('/Aurel-retina-master/retina/screen/map')
sys.path.append('/Aurel-retina-master/retina/screen/transform')
sys.path.append('/Aurel-retina-master/retina/vrf')
sys.path.append('/Aurel-retina-master/retina/vrf/utils')

to the head of retina_worker_only_demo.py

This did not solve the problem as when the code start to use neurokernel, import path still cause errors.

How can I solve the problem related to import path?

By the way, to overcome the problem
TypeError: add_node() takes 2 positional arguments but 3 were given
I changed the code in retina.py from

G_workers_nomaster.add_node(
                        neuron.id+'_photon',
                        {'class': 'BufferPhoton',
                        'name': '{}_buf'.format(name)
                    })

to

G_workers_nomaster.add_node(
                        neuron.id+'_photon',
                        **{'class': 'BufferPhoton',
                        'name': '{}_buf'.format(name)
                    })

I hope this will not cause bug in the future.

I believe that you installed the release that is from 4 years ago.
Please install from master.

Thank you for your quick reply!
I do used an old version, and after I installed from master, I got the problem like this:

Do this mean that I made some mistake when installing cuda or neurodriver?

yiyin · 2021-10-09T17:08:36Z

What's your CUDA version? Try

nvcc --version

iKaHibi · 2021-10-09T17:18:17Z

My CUDA version is V9.0.176 and I am using OpenMPI-4.1.0.

yiyin · 2021-10-09T17:29:08Z

That version of CUDA does not support sm_75. I wonder where that came from. What GPU card do you have?

iKaHibi · 2021-10-09T17:42:00Z

I got a nvidia rtx 2060.

yiyin · 2021-10-09T19:37:36Z

Yeah, your CUDA version is too low for this card. Try update to the latest NVIDIA driver and CUDA.

iKaHibi · 2021-10-10T04:25:26Z

Thank you for your response!
After updating my CUDA to 11.3 and reinstalled pyCUDA and scikit-CUDA, I met new error:

pycuda._driver.MemoryError: cuMemAllocPitch failed: out of memory

Does this mean the video memory of my GPU is not enough to run the code?

yiyin · 2021-10-10T06:22:13Z

The full model requires about 4GB of GPU memory. The standard memory configuration for 2060 should have 6GB.
But if you really have less memory, try to run a smaller model, to start with, reduce the number of rings to 0 (see also Figure 4a of Neurokernel RFC #3) by setting

[Retina]
  rings = 0

in your config file. That will run only 1 ommatidium in the center with 6 photoreceptors.

iKaHibi · 2021-10-10T07:07:54Z

I changed the config to

[Retina]
    rings = 0

and got the following feedback:

--------------------------------------------------------------------------
mpiexec has exited due to process rank 0 with PID 0 on
node akiohibi-Sys exiting improperly. There are three reasons this could occur:

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"

3. this process called "MPI_Abort" or "orte_abort" and the mca parameter
orte_create_session_dirs is set to false. In this case, the run-time cannot
detect that the abort call was an abnormal termination. Hence, the only
error message you will receive is this one.

This may have caused other processes in the application to be
terminated by signals sent by mpiexec (as reported here).

You can avoid this message by specifying -quiet on the mpiexec command line.
--------------------------------------------------------------------------

And, surprisingly, as I reboot my computer and change config back to

[Retina]
   rings = 14

I got a different error saying:

Is this caused by mistake in scikit-cuda installing?

yiyin · 2021-10-10T07:44:21Z

I am not clear why cublasCreate failed to initialize, as a handle has been created when getting the version number (that's what these warnings are about) and no error was report then.

You might want to check your LD_LIBRARY_PATH to make sure that it's getting the right path to the libcublas.so from the current version of CUDA. You can check the version of cublas by

import skcuda.cublas as cublas
print(cublas._cublas_version)

make sure that this version is consistent with the libcublas.so.x.x.x in your CUDA path.
