load_parameters() fails with error: no attribute 'params'

[hongzhiyou]

The following codes are my setup file:

This setup file initializes the setup

Import libraries

import pyNCS import pyNCS.neurosetup from pylab import show import pyST

Define file paths

prefix='./chipfiles/' setuptype = 'setupfiles/4bit_setuptype.xml' setupfile = 'setupfiles/zenzero.xml'

Initialize setup

nsetup = pyNCS.neurosetup.NeuroSetup(setuptype,setupfile,prefix=prefix)

clear mapper

nsetup.mapper.clear_mappings();

chip1 = nsetup.chips['ifslwta']; nsetup.chips['ifslwta'].load_parameters('biases/Biases_ifslwta');

However, there is a mistake in the last line: nsetup.chips['ifslwta'].load_parameters('biases/Biases_ifslwta');

ERROR: An unexpected error occurred while tokenizing input The following traceback may be corrupted or invalid The error message is: ('EOF in multi-line statement', (8, 0))

Do you know what is the problem?

You probably don't have the latest version of pyAMDA (the driver for the AMDA board). Please update and install the latest version of pyAMDA. Please confirm weather or not this fixes the problem.

[hongzhiyou]

Thanks. It fixed the problem.

There is another problem. Clearing mapping table... ... done! tmp_mapping_october 100% 19KB 19.4KB/s 00:00

I did not suffer this problem before. Does the following code lead to this problem?

stim = pyST.merge_spikelists(stim_inh[pop_inh_seq.soma.channel], stim_exc_seq10[pop_exc_seq1.soma.channel],stim_exc_seq11[pop_exc_seq1.soma.channel],stim_exc_seq20[pop_exc_seq2.soma.channel],stim_exc_seq21[pop_exc_seq2.soma.channel],stim_exc_seq22[pop_exc_seq2.soma.channel],stim_exc_seq23[pop_exc_seq2.soma.channel])

[sheiksadique]

I think the problem is that you are using an older version of pyST. Please uninstall your pyST and use pyNCS.pyST instead.

Also since this is a different issue from what was originally reported, try to open a different issue (next time). It is just useful; next time some one else has a similar error, they can refer to the corresponding issue thread.

[hongzhiyou]

Sadique, there is no function named "merge_spikelists" in pyNCS.pyST.

[sheiksadique]

Okk i have added the functions to the main import. Please update (git pull) your pyNCS and check now.
