plotly orca not working on aws ec2 instance

问题 I followed this to install conda plotly-orca on an AWS EC2 instance (built on anaconda-python3 image) but hit Cannot open shared object error when orca is invoked. The fix is to install libgtk2.0-0 and libgconf-2-4 packages which unfortunately are not available on AWS EC2 linux distribution (non ubuntu ). So I downloaded this standalone orca-1.3.1.AppImage for linux. I use --appimage-extract to extract orca-1.3.1.AppImage to /home/ec2-user/squashfs-root folder and run: xvfb-run --auto

Plotly missing orca

由 五迷三道 提交于 2020-05-13 14:11:37
问题 I have small problem when exporting static chart using plotly. Plotly does not correctly recognize that I have orca installed and I have still error related to missing orca. I try to change the orca directory but it is still not working. Anyone who knows what is wrong? My code: import plotly.graph_objects as go import orca import plotly #%% fig = go.Figure(data=go.Candlestick(x=pricedata.index, open=pricedata['bidopen'], high=pricedata['bidhigh'], low=pricedata['bidlow'], close=pricedata[

Greenplum ：基于 PostgreSQL 的分布式数据库内核揭秘 (上篇) https: // www.infoq.cn/article/3IJ7L8HVR2MXhqaqI2RA 学长的文章.. 姚延栋 阅读数：714 2019 年 9 月 15 日 17:11 本文经授权转载自公众号 PostgreSQL 中文社区，主要介绍了 Greenplum 集群概述、分布式数据存储和分布式查询优化。 一、数据库内核揭秘 Greenplum 是最成熟的开源分布式分析型数据库（今年 6 月份预计发布的 Greenplum 6 之 OLTP 性能大幅提升，将成为一款真正的 HTAP 数据库，评测数据将于近期发布），Gartner 2019 最新评测显示 Greenplum 在经典数据分析领域位列全球第三，在实时数据分析领域位列并列第四。两个领域中前十名中唯一一款开源数据库产品。这意味着如果选择一款基于开源的产品，前十名中别无选择，唯此一款。Gartner 报告原文。 那么 Greenplum 分布式数据库是如何炼成？众所周知 Greenplum 基于 PostgreSQL。PostgreSQL 是最先进的单节点数据库，其相关内核文档、论文资源很多。而有关如何将单节点 PostgreSQL 改造成分布式数据库的资料相对较少。本文从 6 个方面介绍将单节点 PostgreSQL

How to install Orca - which Windows SDK(s) contain the Orca MSI editing tool?

由 a 夏天 提交于 2020-01-22 07:19:08
问题 According to various web pages, orca.msi/orca.exe is primarily distributed as part of the Windows SDK. I have Visual Studio 2015 Professional Update 3 installed. I have installed all the "Universal Windows App Development Tools" components, which includes three different versions of the Windows 10 SDK (10.0.14393, 10.0.10586, 10.0.10240). But I can't find orca.msi or orca.exe anywhere on my machine. Is this tool no longer packaged with the Windows SDKs? Do I need to install one of the older

MSI package property table entries to enable update releases

由 六月ゝ 毕业季﹏ 提交于 2019-12-24 16:03:43
问题 I use a program called MSICREATE to generate msi packages for a piece of software. I then use orca to transform the msi package. Things work ok but users must delete the existing product before installing an update. I'd like to modify the msi package so the installer recognizes a newer or different version is being installed and removes the current version and then installs the new msi package. What property table entries are needed? ========= The answer given below has helped me get beyond

Is it possible to programatically change an msi's database on Linux

由 偶尔善良 提交于 2019-12-23 02:01:55
问题 I know you can change it using cscript.exe on Windows. Is there a Linux program providing cscript-like functionality? Or is there some other way I can change the database in Linux? 回答1: CScript is just the script execution engine; it knows nothing about MSI directly. Check out Wine; it implements some/most of msi.dll, so as long as functions like MsiDatabaseOpenView and MsiViewExecute are correctly implemented, you should be able to use it to modify an .msi package. 来源： https://stackoverflow

How to extract data (file count) from MSI “File” Table

问题 In our build process there is currently the potential for non-code based files (such as image files) to be added to our web project, but not included in the MSI installer built by WiX. To help prevent this, I want to perform the following in the AfterBuild target for our WiX project: Get a count of all files built (output from web deployment project) Get a count of all files built into MSI (from "File" table in MSI) Compare counts and fail build if they don't match If I fire up Orca I can
