Hello,

The method **compute\_psd()** is not working when following this tutorial:  
[https://mne.tools/stable/auto\_tutorials/time-freq/10\_spectrum\_class.html](https://mne.tools/stable/auto_tutorials/time-freq/10_spectrum_class.html)

I get the error: ` AttributeError: 'Raw' object has no attribute 'compute_psd'`  
As a positive control, I tried **raw.plot\_psd()**, and that worked fine.

Can you please advise? Many thanks!

```python
    mne.datasets.sample.data_path()
    sample_data_folder = mne.datasets.sample.data_path()
    sample_data_raw_file = (sample_data_folder / 'MEG' / 'sample' /
                        'sample_audvis_raw.fif')
    raw = mne.io.read_raw_fif(sample_data_raw_file, verbose=False).crop(tmax=60)
    raw.plot_psd()
    raw.compute_psd()

```

Python: 3.10.6 | packaged by conda-forge | (main, Aug 22 2022, 20:41:22) [Clang 13.0.1]

Hello, I believe you need MNE-Python 1.2 for this.

@drammock the API docs don’t mention when this method first appeared, this should probably be added?

Beste wishes,

Works like a charm with MNE-Python 1.2. Thank you for your quick help!

Hi Richard,  
Does the compute\_psd() removed in the later release?  
I am using mne=1.6.0, and I got the following error:  
AttributeError: ‘RawEDF’ object has no attribute ‘computer\_psd’.

Could you please advise?

Regards,  
Long

you should now use:

I think you have a typo there. It’s `compute_psd`, not `computer_psd`.
