This error occurs when you are trying to use the variable or module 'pd' but it has not been defined or imported in your code.
To fix this error, you need to import the required module. In this case, 'pd' most likely refers to the pandas library, which can be imported using:
```python
import pandas as pd
```
Once you have imported pandas, you can use its functions and attributes by prefixing them with 'pd.' as shown below:
```python
df = pd.DataFrame(data)
```
Make sure that you have installed pandas library in your system.

It seems like you are encountering an error in your Jupyter Notebook. The error message "name 'pd' is not defined" suggests that the variable 'pd' is not recognized or imported.
To resolve this issue, you need to import the necessary library before using it. In this case, it appears that you are trying to use the 'pd' alias for the pandas library.
You can import pandas by adding the following line at the beginning of your code:
```python
import pandas as pd
```
By importing pandas this way, you can use the 'pd' alias to access pandas functions and classes throughout your code.
如何解决name 'pd' is not defined
这个错误通常出现在使用Python Pandas库时,因为代码中缺少导入Pandas库的语句。要解决这个错误,你需要在你的代码中添加以下导入语句:
```
import pandas as pd
```
这将导入Pandas库并将其命名为“pd”,以便在你的代码中使用。如果你已经添加了这个导入语句,那么可能是因为你没有正确安装Pandas库。你可以通过在终端或命令提示符中运行以下命令来安装Pandas库:
```
pip install pandas
```
如果你使用的是Anaconda,可以使用以下命令安装:
```
conda install pandas
```
安装完成后,重启你的Python环境,重新运行你的代码即可。
