Answer 1

import matplotlib 
matplotlib.use("Agg") 
import matplotlib.pyplot as plt

这对我有用

Answer 2

Dhanisha的回答工作得很好，因为我在顶部添加了解释

删除

-Wall -Wpedantic -Wstrict-prototypes -Werror

添加

import matplotlib.pyplot as plt

这种行为背后的原因是如果你在服务器交换机上运行它没有gui支持或非交互模式。如果你在jupyter笔记本上运行相同的代码，它将正常工作。

Answer 3

以下命令对我有用：

<form string="Confirm Draft Invoices">
     <p class="oe_grey">
      Once draft invoices are confirmed, you will not be able
      to modify them. The invoices will receive a unique
      number and journal items will be created in your chart
      of accounts.
      </p>
      <footer>
         <button string="Confirm Invoices" name="invoice_confirm" type="object" default_focus="1" class="btn-primary"/>
         <button string="Cancel" class="btn-default" special="cancel"/>
      </footer>
 </form>

导入matplotlib.pyplot为plt，ImportError：libGL.so.1：无法打开共享对象文件：没有这样的文件或目录
