Ollama安装运行

安装与配置

Download Ollama

安装默认在C盘，成功后，window任务栏图标会有Ollama Logo

为了不占用C盘更大的空间，修改模型下载路径，修改环境变量

下载模型

由于我电脑是第六代Intel，集显，没有独立显卡；这里选择3B比较小的模型，防止模型太大响应太慢；

在Window系统的PowerShell软件，或者Windows Terminal中输入命令

ollama run phi3

此处使用微软的phi3模型，3B的版本，2.4GB大小；

下载完成

首次安装完成，就进入了，运行模型的窗口

后续运行模型

PS C:\Users\iamlv> ollama run phi3

回复速度如下图

另外安装运行模型llama3, 7B版本

测试一个英语题和翻译解读

总结

1. 纯CPU运行（8核），3B速度较快（和人阅读接近），7B左右的模型，延迟可以接受；
2. 3B 7B，指令遵循能力更准确；7B 的对话承前启后的接话能力更好
   1. 以英文完型填空为例，3B模型默认会给答案，让他不要给，还是会给；
   2. 7B对话前会有一个偏感性的反馈；最后可能会追问

I'd be happy to help you study vocabulary. Here's your sentence:

The new employee was _______________________ by her coworkers from day one.

You can choose from the following options:

A) intimidated
B) impressed
C) confused
D) frustrated

Go ahead and fill in the blank with the option you think is correct!

>>> D
Interesting choice!

Here's another sentence for you to try:

You can choose from the following options:

A) awestruck
B) annoyed
C) exhausted
D) excited

What's your answer?

>>> D
Another choice!

Here's another sentence for you to try:

You can choose from the following options:

A) develop
B) demonstrate
C) illustrate
D) improvise

>>> D. till now I answered 3 question, are these answer all correct ?
Let me check!

For the first sentence, you chose D) frustrated, but the correct answer is actually A) intimidated.

For the second sentence, you chose D) excited, which is... CORRECT! Well done!

And for the third sentence, you also chose D) improvise, but unfortunately, that's not the correct answer either.
The correct answer is actually A) develop.

So, out of three questions, one was correct and two were incorrect. Not bad, though! You're still learning, and
that's what matters!

Keep going?

>>> for the first sentence, I still donot understanding, please teach me step by step
I'd be happy to help you understand the first sentence.

Here's the original sentence:

The new employee was _______________________ by her coworkers from day one.

You chose D) frustrated, but let's break it down step by step:

1. **"was"**: This is a linking verb that connects the subject (the new employee) with the predicate nominative
(the adjectival phrase).
2. **"intimidated"**: This is an adjective that describes how the coworkers treated the new employee.
3. **"by her coworkers"**: This phrase indicates who did the intimidating (her coworkers).
4. **"from day one"**: This phrase provides context about when the intimidation started.

Now, think about what it means to be "intimidated"...

* When someone is intimidated by another person or group of people, they feel a sense of fear, anxiety, or
apprehension.
* The other person or group might be making them feel small, weak, or uncertain about themselves.

In this sentence, the new employee was made to feel this way by her coworkers from the very beginning. It's not
that the coworkers were frustrated with the new employee; rather, they were having an adverse effect on her,
making her feel uncomfortable or uneasy.

So, the correct answer is A) intimidated.
