无法在ubuntu18.04 64位计算机上安装anaconda 5.3.1 Anaconda3-5.3.1-Linux-x86_64.sh

Question

我正在尝试在64位ubuntu 18.04上安装anaconda。 我正在按照以下步骤进行操作

1）从https://www.anaconda.com/download/#linux

下载了64位安装程序

2）在终端中运行以下代码

cd Downloads
sudo bash Anaconda3-5.3.1-Linux-x86_64.sh

           WARNING:
Your operating system appears not to be 64-bit, but you are trying to
install a 64-bit version of Anaconda3.
Are sure you want to continue the installation? [yes|no]

我检查了系统配置：

System Configuration

OS类型为64位，处理器为ARMv8。

请问为什么我可能会遇到此错误？
