<p>Hi Alex, </p>
<p><br>
</p>
<p>I'm using the standard <span>mne.compute_covariance call</span></p>
<p><span><br>
</span></p>
<p><span>cov = mne.compute_covariance(epochs['condition'], method = 'shrunk', n_jobs = 3).</span></p>
<p><span><br>
</span></p>
<p><span>I've attached a link to the error below. Also, I've tried using the PCA method and get another error message (with the helpful suggestion to contact you guys at the end!). Please find the link below too.</span></p>
