Sympy在终端工作，但在Jupiter Notebook或Jupyterlab中工作，有什么建议吗？

硬件/软件：
MacBook Pro 16英寸，2021 -M1 Max（Macos Monterey版本12.4）和Python 3.9.13。

已经尝试过：

pip install sympy
pip install -u sympy
conda安装sympy
conda install -c conda-forge sympy

在终端中工作正常：

>>> from sympy import *
>>>

但是在jupyter-lab和jupiter笔记本中：

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Input In [1], in <cell line: 1>()
----> 1 from sympy import *

ModuleNotFoundError: No module named 'sympy

Hardware/Software:
MacBook Pro 16-inch, 2021 - M1 max (macOS Monterey Version 12.4) and Python 3.9.13.

Have tried:

pip install sympy
pip install -U sympy
conda install sympy
conda install -c conda-forge sympy

In terminal it works fine:

>>> from sympy import *
>>>

But in both jupyter-lab and Jupiter notebook:

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Input In [1], in <cell line: 1>()

ModuleNotFoundError: No module named 'sympy

@creanion提出的调试步骤

a：
在终端：

  $ python

＆gt;＆gt;＆gt; sys.version_info


sys.version_info（major = 3，次要= 9，micro = 13，reareelevel ='final'，serial = 0） 

＆gt;＆gt;＆gt; Sys.cutable
/usr/local/caskroom/miniforge/base/bin/python

 ＆gt;＆gt;＆gt; Platform.Processor（）

 'i386'

 b
 在jupyter-lab中： 

sys.version_info
 sys.version_info（major = 3，次要= 10，micro = 4，reareelevel ='final'，serial = 0）

Sys.cutable

'/library/frameworks/python.framework/versions/3.10/bin/python3.10'

Platform.Processor（）

'手臂'

创建@hrokr建议的虚拟环境
安装
```
  conda create -n pyc39 python = 3.9

 
```

安装ipykernel

不确定我是否应该在此步骤之前激活env，或者这里的所有内容都是必要的，但是以下是全局安装的

  conda安装ipykernel

python3 -m ipykernel install -user -name pyc39 -display -name“ pyc39”

conda安装-n Pyc39 nb_conda_kernels

conda安装-N pyc39 ipykernel

activate env，打开jupyter-lab，然后选择新创建的pyc39以验证
```
  conda激活pyc39

jupyer-lab！

来自Sympy Import * 

 
```

Debugging step as proposed by @creanion

a:
In terminal:

$python

>>> sys.version_info


sys.version_info(major=3, minor=9, micro=13, releaselevel='final', serial=0) 

>>> sys.executable
/usr/local/Caskroom/miniforge/base/bin/python

 >>> platform.processor()

 'i386'

 b
 While in jupyter-lab: 

sys.version_info
 sys.version_info(major=3, minor=10, micro=4, releaselevel='final', serial=0)

sys.executable

'/Library/Frameworks/Python.framework/Versions/3.10/bin/python3.10’

platform.processor()

'arm’

Creating virtual environment as suggested by @hrokr
Install
```
conda create -n pyc39  python=3.9
```

Install ipykernel

Was not sure if I should have activated env in prior to this step, and or everything here was necessary, however the following was globally installed

conda install ipykernel

python3 -m ipykernel install --user --name pyc39 --display-name "pyc39”

conda install -n pyc39 nb_conda_kernels

conda install -n pyc39 ipykernel
