Hi , I run this line  
from mne.time\_frequency import psd\_welch

And am getting this Error. few days before it was working normally but now it gives this error:

ImportError Traceback (most recent call last)  
 in   
----\> 1 from mne.time\_frequency import psd\_welch

ImportError: cannot import name ‘psd\_welch’ from ‘mne.time\_frequency’ (/usr/local/lib/python3.8/dist-packages/mne/time\_frequency/ **init**.py)

NOTE: If your import is failing due to a missing package, you can  
manually install dependencies using either !pip or !apt.

Hello,

This function has been deprecated in version 1.2 and removed in version 1.3, recently released.  
Please use `inst.compute_psd()` instead:

- Raw: [mne.io.Raw — MNE 1.2.2 documentation](https://mne.tools/stable/generated/mne.io.Raw.html#mne.io.Raw.compute_psd)
- Epochs: [mne.Epochs — MNE 1.2.2 documentation](https://mne.tools/stable/generated/mne.Epochs.html#mne.Epochs.compute_psd)

```python
raw = ...
spectrum = raw.compute_psd(method="welch")
data, freqs = spectrum.get_data(return_freqs=True)

```
