我在使用 Plotly 生成图表时遇到了错误,它似乎影响了我尝试在其上生成的大多数图表。该错误似乎也是所有故障中的重复错误。我正在使用 Jupyter 笔记本(Anaconda 3、Python 3.6)。
下面找到了无法生成输出的代码(但我的数据表和其他所有内容都是正确的)。
** 我不确定 Plotly 库是否有问题(我正在使用使用“Pip install Plotly”安装的最新 Plotly)

更新:
进一步调查问题后,问题出在袖扣内部文件上。 Cufflinks 与最新版本的plotly存在兼容性问题,这在
Github Issue
中进行了讨论,您可以尝试使用以下命令降级到“plotly 2.7”。这样就可以消除这些错误。
pip uninstall plotly
pip install plotly==2.7.0
正如您在日志中看到的,请参考以下行,它告诉我们实际的问题。
--> 199 layout=Layout(theme_data['layout'])
该行抛出的错误是。
ValueError:
Invalid value of type 'builtins.str' received for the 'bgcolor' property of
layout.legend
Received value: 'pearl02'
The 'bgcolor' property is a color and may be specified as:
- A hex string (e.g. '#ff0000')
- An rgb/rgba string (e.g. 'rgb(255,0,0)')
- An hsl/hsla string (e.g. 'hsl(0,100%,50%)')
- An hsv/hsva string (e.g. 'hsv(0,100%,100%)')
- A named CSS color:
aliceblue, antiquewhite, aqua, aquamarine, azure...
因此您需要将
layout
对象的 bgcolor
属性更改为 pearl02
以外的其他内容,这似乎是问题所在,您可以将布局对象属性更改为。
layout = {
'bgcolor': '#ffffff'
}
请使用以下参考链接了解设置颜色值的不同方法。
截至 2019 年 6 月,这将使您能够启动并运行。 安装袖扣 0.13.0 与...
conda install -c conda-forge cufflinks-py
然后使用...安装/降级到 2.7.0
conda install plotly=2.7.0
袖扣人员已经致力于解决这个问题有一段时间了,但尚未出现。 显然是一项伟大的工作。
研发找到这个解决方案后
只需在 C 盘中搜索 cufflinks 文件夹即可。您将在文件夹中获得.config文件。在记事本中打开该文件。将主题更改为“太阳能”(“主题”:“太阳能”)
错误将被解决
对于 rgba,问题与
a
类型不安全有关。
我在这里对袖扣叉子进行了一些修复:

可以按照PR中的描述直接安装
