Traceback most recent call last : File "test. I have also tested the code on a work laptop which is also running Windows 10 and it has the same issues.

Update for anyone else that encounters this issue, I figured out a hacky workaround to get the process working again. For example. I'm also seeing this fail with orca 1. With an admin account, it works fine. Doing the test gree recommends works fine: even with a non-admin account, plotly can communicate with the orca launched manually, from a non-admin account. I'm not very familiar with Windows security so I'm stumped.

There is no windows firewall. It would still involve some work to start orca as a service and reliably relaunch it if it fails. Maybe keep a pool of orca processes behind a load balancer. Edit: managed to track down my issue by running orca directly from the notebook, got the following error:. Edit: traced that wrong TEMP env var value to my specific notebook setup: using jupyterhub on Windows with winlocalprocessspawner.

It's a bug in winlocalprocessspawner. I encountered this issue when generating a series of eight scatter plots. The first scatterplot haddata points in it. The second one had the original data points, but then added anothercolor coded for another parameter. The error message was:. ValueError: For some reason plotly.

CMD version: 1. Given that the code to generate the eight plots were in a single function, I simply made a separate function for the plot that caused the problem, put the code into it, and called it from the original function.

That worked. All eight plots were generated. Skip to content. Dismiss Join GitHub today GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Sign up. New issue.

Orca can output figures to several raster image formats including PNGJPEGOrca can also output figures in several vector formats including SVGPDF ,This section covers the lower-level details of how plotly.

Please refer to the Static Image Export section for general information on creating static images from plotly. Orca is an Electron application that inputs plotly figure specifications and converts them into static images. Orca can run as a command-line utility or as a long-running server process.

In order to provide the fastest possible image export experience, plotly. By default, plotly. Because of this, the first image export operation in an interactive session will typically take a couple of seconds, but then all subsequent export operations will be significantly faster, since the server is already running.

We can use the plotly. The difference in runtime is dramatic. Starting the server and exporting the first image takes a couple seconds, while exporting an image with a running server is much faster. By default, the orca server will continue to run until the main Python process exits. It can also be manually shut down by calling the plotly.

Additionally, it is possible to configure the server to shut down automatically after a certain period of inactivity. See the timeout configuration parameter below for more information. Regardless of how the server is shut down, it will start back up automatically the next time an image export operation is performed.

If any of my friends are interested in visiting Iceland, I will definitely recommend you and Nordic Visitor to them I wish all the best. There where some complications due to the volcano and our itinerary changed, but we had no problems.

It was excellent having the cellphone and we felt comfortable knowing that if things needed to be changed, they would be. Thank you for making our honeymoon stress free. We will use you again in the future. Everything was quiet perfect, the receptions on the hotels, the bedrooms, and the places you recommended to see.

As I said before the standard of accommodation was excellent as the rental car. The standards of the meals were good. The itinerary was excellent (we loved Heimaey, especially the hotel). Well, we were a bit surprised (positively) because we didn't have any references at all about your services (we knew about your travel agency by google), and we can say that if we return to a nordic country maybe it will be using the services of Nordic Visitor.

The only thing we are disappointed is to never knew the person that make this perfect travel organization. But still thank you for all. I was initially skeptical of what kind of service we were going to be getting, but everything, top to bottom, was very professional and well put together.

We didn't have much communication with Dagny, but after having met her in person, we felt like we could ask anything of her. We were really regretful that we didn't get to visit the Nordic Visitor office on our last day to give a video review, and to thank her in person.

Have already recommended NV once from our Iceland trip and will absolutely recommend again. Christoph was also wonderful- did a fantastic job in customizing the trip for us (combination of 2 trips), and was also quick to respond and communicate via email.

We will definitely book again- the only negative is that the time went by too quickly. We have just arrived back from a most memorable and enjoyable trip which you organised for us. Right from the beginning of our email correspondence, we have been impressed by the quality, dedication and effort you have put into making our tour of Scotland enjoyable. Thank you for going beyond what I would normally expect. The tour and the associated paperwork and maps which you arranged were all marvellous and a good representation of Scotland.
