Python fluid import error

[yeyupiaoling]

I import fluid is this line, This is new Fluid:

import paddle.fluid as fluid

No error info,only this line:

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

@yeyupiaoling We shall look at this. Is #308 identical?

[varunarora]

Hey @yeyupiaoling, have you followed the instructions to install PaddlePaddle on your computer before running this script? VisualDL unfortunately won't install this for you automatically.

These instructions are available on the PaddlePaddle website paddlepaddle.org.

@varunarora
Hi, I tried this demo, no problem.

visualDL --logdir=scratch_log --port=8080
# visit http://127.0.0.1:8080

And my PaddlePaddle is no problem too.

I think the problem is an new Fluid can't ues in VisualDL,

[varunarora]

@yeyupiaoling Got it - we are looking into it!

[yeyupiaoling]

@varunarora
I got newest PaddlePaddle in this doc:http://paddlepaddle.org/docs/develop/documentation/en/build_and_install/build_from_source_en.html

[varunarora]

@yeyupiaoling Yeah your probably right, we are talking to the core team right now to see what happened

[yeyupiaoling]

@varunarora
I found import different order will happen different error, like:

import paddle.fluid as fluid
from visualdl import LogWriter

and

from visualdl import LogWriter
import paddle.fluid as fluid

[varunarora]

That is really strange... @jetfuel probably has some views on this

@varunarora @jetfuel
You can try my code:https://github.com/yeyupiaoling/TestVisualDL/blob/master/code/TestVisualDL.py
And you should see these log:

@varunarora @jetfuel
I need help.

[varunarora]

@yeyupiaoling We understand and can promise we are on it. Sorry for the delays - we are trying to do what we can.

[varunarora]

@yeyupiaoling I think there is some issue with your environment / Paddle build. We have tried it on Mac OSXs 10.12s and Python 2.7 and it seems to be fine, including your script.

Can you give us a little info on your environment? Anything other than the air pollution ;)

[yeyupiaoling]

@varunarora
Mac? My environment is 64 bit Ubuntu 16.04

[varunarora]

@yeyupiaoling Ubuntu is the primary environment in which most people work on Paddle - so you should be fine. Have you tried using it on Docker?
