"Error writing to output stream" on alternating calls of run_code() #180
Description
my initial discovery of this issue is outlined at #171
I suspect that this is the same problem as Calysto/matlab_kernel#8
Basically, I'm running pymatbridge from an iPython notebook server. The first Matlab() instance (or the first matlab_kernel that is created) returns "Error writing to output stream" on every other call
So the following code...
from pymatbridge import Matlab
mlab = Matlab()
mlab.start()
print mlab.run_code('a = [1,2,3,4]')
print mlab.run_code('a = [1,2,3,4]')
print mlab.run_code('a = [1,2,3,4]')
print mlab.run_code('a = [1,2,3,4]')returns
{u'content': {u'datadir': u'/tmp/MatlabData/', u'code': u'a = [1,2,3,4]', u'figures': [], u'stdout': u'\na =\n\n 1 2 3 4\n\n'}, u'success': u'true'}
{u'content': {u'code': u'a = [1,2,3,4]', u'stdout': u'Error writing to output stream.\n\n'}, u'success': u'false'}
{u'content': {u'datadir': u'/tmp/MatlabData/', u'code': u'a = [1,2,3,4]', u'figures': [], u'stdout': u'\na =\n\n 1 2 3 4\n\n'}, u'success': u'true'}
{u'content': {u'code': u'a = [1,2,3,4]', u'stdout': u'Error writing to output stream.\n\n'}, u'success': u'false'}
Bizarro.
Also, the figures it returns are not formatted the same as subsequent instances. The are smaller and more pixelated.
