I ran the following from the PythonSlicer console:

```auto
from slicer.util import pip_install
pip_install("pandas>2")

```

and received the following error:

```auto
Traceback (most recent call last):
 File "<console>", line 1, in <module>
 File "/Applications/Slicer.app/Contents/bin/Python/slicer/util.py", line 3571, in pip_install
   _executePythonModule('pip', args)
 File "/Applications/Slicer.app/Contents/bin/Python/slicer/util.py", line 3533, in _executePythonModule
   logProcessOutput(proc)
 File "/Applications/Slicer.app/Contents/bin/Python/slicer/util.py", line 3502, in logProcessOutput
   raise CalledProcessError(retcode, proc.args, output=proc.stdout, stderr=proc.stderr)
subprocess.CalledProcessError: Command '['/Applications/Slicer.app/Contents/bin/../bin/PythonSlicer', '-m', 'pip', 'install', 'pandas>2']' returned non-zero exit status 1.

```

Does anyone more experienced than I am know what might be going on? Thanks!

Hi @Misterkim,

pandas usually installs fine for 3D Slicer.  
What you can test is opening the command prompt and run the pip install command manually to get more information on what went wrong.

In your case something like :

```auto
/Applications/Slicer.app/Contents/bin/PythonSlicer -m pip install pandas>2

```
