Docker: Connection refused
Hi, I'am unable to write images using the docker image of orca.
To reproduce the problem:
import time
import plotly.io as pio
import plotly.graph_objects as go
plotly.io.orca.ensure_server()
time.sleep(30)
fig = go.Figure(
data=[go.Bar(x=[1, 2, 3], y=[1, 3, 2])],
layout=go.Layout(
title=go.layout.Title(text="A Bar Chart")
)
)
fig.write_image("test.pdf")
The error:
---------------------------------------------------------------------------

I tried the solution offered in https://github.com/plotly/orca/issues/164 (adding time.sleep) to no avail. So this must be another problem.

I am using linux and did some tests to see if docker was working correctly. I tried https://github.com/qdm12/port-checker and other images. coudn't find any problems.
I am sorry you are running into all sorts of issues @fthalabi and thank you for trying to get this work!
It seems that plotly.py is trying to start Orca on a different port which may not be accessible to the outside world (ie. your host machine). Using --net=host may fix the problem.
However, one cleaner solution IMHO and the one I typically use is to launch Orca myself and point plotly.py to it. So if start Orca on localhost on port 9091, I simply have to do the following from python:
import plotly.io as pio
pio.orca.config.server_url = "http://localhost:9091"
and then things should just work :smile_cat:
I'm sorry to bother, I really did try to get it running before asking.
import plotly.io as pio pio.orca.config.server_url = "http://localhost:9091"
Do you use only those options @antoinerg ? I don't get a server with that.
In [1]:import plotly.io as pio
In [2]:pio.orca.config.server_url = "http://localhost:9091"
In [3]:pio.orca.ensure_server()
In [4]:pio.orca.status
Out [4]:
orca status
-----------
state: unvalidated
executable: None
version: None
port: None
pid: None
command: None
Thanks for the help.
@fthalabi Yes the above should work if you have an Orca instance running and accessible at the address you provided. Just create a figure and write an image to check:
fig = go.Figure(
data=[go.Bar(x=[1, 2, 3], y=[1, 3, 2])],
layout=go.Layout(
title=go.layout.Title(text="A Bar Chart")
)
)
fig.write_image("test.pdf")
I'm having this issue as well. I have a docker-compose with a plotly environment in one container and the quay.io/plotly/orca image running in another container.
I know the orca server is running because I can go to localhost:9091 in my browser and the request is logged in the container. However, when trying to use pio in my plotly container, I cannot connect to the server.
Plotly.py was unable to communicate with the orca server at http://localhost:9091
Please check that the server is running and accessible.
Just to be sure @hiramf, can you go to localhost:9091 from within the container making the call to Orca?
@antoinerg, negative, so more likely an issue with my configuration? Using netcat and python/requests both yielded connection refused.

Yes! The problem is that localhost is a different destination depending on where it's called from. From the container, you can try to reach Orca (running on your host machine) by replacing localhost by the IP address of your host.
Got it! Confirmed working by spinning up an instance on Azure and setting pio.orca.config.server_url.
One thing to note is that pio.orca.status still returns even after successfully running fig.write_image(test.png):
>>> pio.orca.status
orca status
-----------
state: unvalidated
executable: None
version: None
port: None
pid: None
command: None
@hiramf I'm glad this fixed your issue!
About the pio.orca.status, I agree that the output is not user-friendly at all. I will open an issue over at https://github.com/plotly/plotly.py
EDIT: https://github.com/plotly/plotly.py/issues/2222
Hi team, I've produced the same code and followed the steps indicated and still getting a connection error.
import time
import plotly.io as pio
import plotly.graph_objects as go
plotly.io.orca.ensure_server()
time.sleep(30)
fig = go.Figure(
data=[go.Bar(x=[1, 2, 3], y=[1, 3, 2])],
layout=go.Layout(
title=go.layout.Title(text="A Bar Chart")
)
)
fig.write_image("test.pdf")
After this I get a MaxRetryError. I've tried just about everything I can find, including setting separate server_urls and ports, but to no avail. I'm admittedly new to this and a bit confused:

I can get a Plotly images to show in the browser via the traditional fig.show(), and when I create an image with orca according to documentation, it works fine (although my '.svg' still produces a '.png', which seems another issue entirely.
orca graph "{ \"data\": [{\"y\": [1,2,1]}] }" -o fig.png
I should finally say I'm not using docker, I'm just running this on a Jupyter Notebook, but I've tried running from command line as well. I've been able to get the orca server up and running, but could it be some Firewall issue? I have almost 0 experience with that unfortunately, so not sure how to troubleshoot that aspect. After scouring the web this issue thread seemed my best hope... I appreciate any help or direction, thanks!

I was able to avoid the write_image() phenomenon altogether by using plotly iplot. Not the static image export service I was hoping to use, but it works.
The below downloads an svg... and crisp images have been restored!
from plotly.offline import iplot
import plotly.graph_objs as go
import numpy as np
np.random.seed(1)
N = 100
random_x = np.linspace(0, 1, N)
random_y0 = np.random.randn(N) + 5
random_y1 = np.random.randn(N)
random_y2 = np.random.randn(N) - 5
# Create traces
fig = go.Figure()
fig.add_trace(go.Scatter(x=random_x, y=random_y0,
mode='lines',
name='lines'))
fig.add_trace(go.Scatter(x=random_x, y=random_y1,
mode='lines+markers',
name='lines+markers'))
fig.add_trace(go.Scatter(x=random_x, y=random_y2,
mode='markers', name='markers'))
fig
iplot(fig, image='svg', filename='line_test_image')
I've been able to get the orca server up and running, but could it be some Firewall issue?
Can you verify that you're able to go to 127.0.0.1:9091 (or whichever port your orca server is running on) and see that you get a response? (should say json parse error in the browser)
Also, the error message you posted says it is looking at a different port than what I believe is the default (9091).
