NameError: name 'file' is not defined in hbp_cells.py #2

cristi-zz · 2018-12-11T13:17:54Z

Hi!
I cloned the library,
created neurocnn env, (using conda and environment3.yml, and I got python 3.6.6),
installed NEURON with some trouble (neuron.__version__ is 7.6.2-3-g9f36b13)
installed and compiled LFPy
ran python hbp_cells.py compile and it ended with Successfully created x86_64/special
and then, tried to run do_all_cell_simulations:
python do_all_cell_simulations.py -probe Neuronexus-32-Kampff -n 10

I got the following errors: (13 times):

LFPy imported
neuron imported
Simulating  L5_TTPC1_cADpyr232_1
Traceback (most recent call last):
  File "hbp_cells.py", line 777, in <module>
    cell = run_cell_model(cell_folder, model, vm_im_sim_folder, int(numb))
  File "hbp_cells.py", line 281, in run_cell_model
    cell = return_cell(cell_model, model_type, cell_name, T, dt, 0)
  File "hbp_cells.py", line 123, in return_cell
    f = file("template.hoc", 'r')
NameError: name 'file' is not defined

The offending code:

def get_templatename(f):
    .........
    templatename = None
    f = file("template.hoc", 'r')
    for line in f.readlines():
    .........

(1) Is file() something that had to be imported from somewhere?

I replaced it with open() [added file=open at the beginning of the hbp_cells.py] assuming that the intention was to read the text contents of the .hoc files.

Then, I got the following error:

Hi,
this probably comes down to the NEURON version. For some reason, unknown to me, the cells from the HBP database does not appear to be working for us with version 7.6, while working just fine on 7.5, see similar problem in:
https://github.com/alejoe91/MEArec/issues/6

Sadly, I do not at the moment know why this problem occurs, or how to deal with it, except switching to NEURON 7.5

cristi-zz · 2018-12-11T13:25:50Z

UPDATE
Ok, I installed neuron 7.5 from conda-forge.
I re-installed LFPy, removed and re-compiled the .mod files, and now I got some activity. (eg. processor is working).
Unfortunately there still is an error:

Hm, I will let the script finish, and then focus on this xrange. I guess it is another leftover from python 2.7

torbjone · 2018-12-11T13:31:21Z

OK, I would appreciate it very much if you let us know if this solves the problem.

cristi-zz · 2018-12-11T14:25:11Z

Hi! The script ran without errors, afaik. Of course, I replaced the xrange with range.

There is still an warning, I don't know if it is relevant or not: UserWarning: Membrane currents do not sum to zero

This is the output of 13th cell type or so:

@torbjone thank you for looking into this! If the above output looks ok, imho, you can close this issue (unil NEURON 7.7 will be deployed to conda-forge and a new pull request is made here, fixing the python 2 leftovers.)

Thank you again!

alejoe91 · 2018-12-11T16:29:51Z

Hi @cristi-zz! The output looks good. Thanks @torbjone for sorting this out

nrnhines · 2018-12-12T15:13:07Z

It is possible that this problem may be related to neuronsimulator/nrn#130
which is fixed by changeset neuronsimulator/nrn@f837b5c

orena1 mentioned this issue Dec 11, 2018

Loading import3d before loading modfile create an execption (only in Neruon 7.6) neuronsimulator/nrn#130
