IOError: [Errno 2] No such file or directory: 'tmp/demo_auto_tune.png' #48
Description
Dear contributor,i encountered another problem in step 2.
after using the command export PYTHONPATH=.
this command python python/demo_auto_tune.py can be executed
however at the end of execution,it reports a error like below:
cno=12 key=nprobe=4096 perf=0.9870 t=11.214
Traceback (most recent call last):
File "python/demo_auto_tune.py", line 168, in <module>
fig.savefig('tmp/demo_auto_tune.png')

self.canvas.print_figure(*args, **kwargs)

filename_or_obj = open(filename_or_obj, 'wb')
IOError: [Errno 2] No such file or directory: 'tmp/demo_auto_tune.png'
i don't know whether this problem is due to the matplotlib module of my python.
thank you for your patient reply!
