我已pyodbc安装并尝试连接到服务器，但pyodbc找不到驱动程序。我做了以下事情：

  1. 安装pyodbc使用pip：

    pip install pyodbc

  2. 按照微软的指示。

  3. 运行一个测试脚本：

    import pyodbc 

print(pyodbc.drivers())

    它返回一个空数组。

我还需要做什么？我在 Anaconda Python 安装中的 Jupyter Notebook 中运行脚本。

python drivers odbc mssql

我正在尝试删除旧版本的 eclipse (3.8)，但我不知道包名称。有人可以解释如何正确找到包名吗？

我试过这个，但是当我对这些名称进行自动删除时，它找不到包：

king@king-Inspiron-7352 ~ $ apt list --installed |grep eclipse

我正在尝试将一堆图像转换为可能位于多个子目录中的缩略图，并将图像的副本保存为子目录中的缩略图，但我无法弄清楚语法。任何的建议都受欢迎。

我正在尝试编写一个 bash 命令来在音频设备（不是不同的卡）之间切换。我找到了有关该主题的AskUbuntu 帖子，然后我开始在下面的列表中尝试每个输出设备，以确定哪个是我的扬声器，哪个是我的耳机。有没有更好的方法？

我尝试了什么：

pactl set-card-profile 0 output:hdmi-surround71

对于每个音频设备，从扬声器到耳机输出没有变化。

我正在使用以下设置从 Geforce 970 上运行 3 台显示器：

  1. Mon1 (1024x768) 连接到 DVI 端口（原始分辨率 1920x1080）
  2. Mon2 (1920x1080) 连接到显示端口
  3. Mon3 (1920x1080) 连接到显示端口

将 Mon1 上的分辨率强制为 1920x1080 的正确方法是什么？我需要覆盖 xorg.conf 中的某些内容吗？或在 nvidia-settings-rc 文件中？

我正在尝试使用以下命令输入创建启动器：

gksu sh -c "~/evelauncher/evelauncher.sh"

但它失败了。当我输入：

sudo ~/evelauncher/evelauncher.sh

在终端中它完美地工作（带有文本输出）并启动程序。有人可以解释为什么启动器不起作用吗？启动器作为我的用户具有读写访问权限，并且选中了“将文件作为程序执行”复选框。

我刚刚使用存储的设置文件更新了 dconf，dconf load /org/cinnamon/ < keyboard_shortcuts_export_dconf然后对文件进行了一些更改（交换firefox为google-chrome）并尝试使用相同的命令导入文件。它没有给出错误，但更改没有生效（当我使用快捷方式时，它仍然在 Firefox 中打开）。我必须使用某种source命令来刷新文件或其他东西吗？
