密谋失踪的逆戟鲸

【中文标题】密谋失踪的逆戟鲸【英文标题】：Plotly missing orca 【发布时间】：2020-02-16 19:22:57 【问题描述】：使用 plotly 导出静态图表时遇到小问题。
Plotly 无法正确识别我已安装 orca，并且仍然存在与缺少 orca 有关的错误。我尝试更改 orca 目录，但它仍然无法正常工作。有谁知道怎么回事？
我的代码：
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['bidclose']),)
#%%
fig.show()
#%%
plotly.io.orca.config.executable = r'C:\Users\Kuba\AppData\Local\Programs\Python\Python37\Lib\site-packages\orca'
plotly.io.orca.config.save()
#%%
fig.write_image("images/fig1.png")
这里描述了如何解决它，但它对我不起作用：
https://plot.ly/python/orca-management/#configuring-the-executable
orca 版本是 1.5.1
谢谢。

If you haven't installed orca yet, you can do so using conda as follows:
$ conda install -c plotly plotly-orca
Alternatively, see other installation methods in the orca project README at
https://github.com/plotly/orca.
After installation is complete, no further configuration should be needed.
If you have installed orca, then for some reason plotly.py was unable to
locate it. In this case, set the `plotly.io.orca.config.executable`
property to the full path of your orca executable. For example:
>>> plotly.io.orca.config.executable = '/path/to/orca'
After updating this executable property, try the export operation again.
If it is successful then you may want to save this configuration so that it
will be applied automatically in future sessions. You can do this as follows:
>>> plotly.io.orca.config.save()
If you're still having trouble, feel free to ask for help on the forums at

错误信息是什么？ 我编辑了原帖。 【参考方案1】：试试万花筒，它对我有用。 它是虎鲸的替代品
conda install -c plotly python-kaleido
【讨论】：
【参考方案2】：来自plotly docs
pip install -U kaleido
【讨论】：
【参考方案3】：在 Windows 上使用 Pycharm 和 Python 3.6 对我有用的是：
遵循https://github.com/plotly/orca#installation - 方法 4：独立二进制文件：
从https://github.com/plotly/orca/releases下载windows-release.zip 安装可执行文件 右键单击桌面新创建的 Orca 图标以获取应用程序的安装路径。从 plotly\io 文件夹（在我的情况下为 C:\Users\ventafri\AppData\Local\Programs\Python\Python36\Lib\site-packages\plotly\io）打开 _orca.py
替补：
# Try to find an executable
# -------------------------
# Search for executable name or path in config.executable
executable = which(config.executable)
path = os.environ.get("PATH", os.defpath)
formatted_path = path.replace(os.pathsep, "\n ")
与：
# Try to find an executable
# -------------------------
# Search for executable name or path in config.executable
executable = r"C:\Users\ventafri\AppData\Local\Programs\orca\orca.exe"
path = os.environ.get("PATH", os.defpath)
formatted_path = path.replace(os.pathsep, "\n ")

抱歉回复晚了。您的解决方案对我不起作用，但我找到了使用fig.to_html() 的解决方法，然后我可以打开并查看图表并随后转换为图片。也许您的解决方案适用于其他人。
我在 PyCharm 安装 orca 和 plotly 时遇到了这个问题，这个解决方案在那里完美运行
我正在运行以下行：C:\WINDOWS\system32>orca graph " \"data\": [\"y\": [1,2,1]] " -o fig.png 什么都没有发生。有什么想法吗？【参考方案4】：
Susanna 的回答可能要好得多，但对我有用的是降级到 orca 1.2.1：
conda remove plotly plotly-orca
conda install -c plotly plotly-orca==1.2.1
【讨论】：
【参考方案5】： #尝试在 Colab 上安装这些软件包：!pip install plotly==4.7.1
!wget https://github.com/plotly/orca/releases/download/v1.2.1/orca-1.2.1-
x86_64.AppImage -O /usr/local/bin/orca
!chmod +x /usr/local/bin/orca
!apt-get install xvfb libgtk2.0-0 libgconf-2-4
import plotly.graph_objects as go
fig.show()
fig.write_image("figname.png")#change format if needed
fig.show()
fig.write_image("gdrive/My Drive/destinationfolder/figname.png")
【讨论】：
用 colab 之类的 kaleido 是不可能的吗？【参考方案6】：我也面临同样的问题，您可以在使用 plotly 的同时使用 kaleido 保存静态图像。
https://medium.com/plotly/introducing-kaleido-b03c4b7b1d81
【讨论】：
【参考方案7】：我在尝试使用非基本 conda 环境的内核的 jupyter notebook 中生成静态图像时遇到了类似的问题。
我必须在基础环境中安装 plotly-orca 才能正常工作。
【讨论】：
【参考方案8】：对我有用的是从 https://github.com/plotly/orca/releases 安装 .exe 文件
然后使用新创建的 .exe 文件的文件路径运行它。
导入情节 plotly.io.orca.config.executable = '...../orca/orca.exe'
