<p style="margin-top:0;margin-bottom:0">Thank you and unfortunately, still getting the same errors after executing the recommended codes.</p>

<p style="margin-top:0;margin-bottom:0">I am using WIN 64-bits, Python 2.7.14.</p>

<p style="margin-top:0;margin-bottom:0">I have checked the following <span style="font-size: 12pt;">code: </span></p>
<p style="margin-top:0;margin-bottom:0"></p>
<div>import sys</div>
<div>sys.maxint</div>

<div><span style="font-size: 14px; white-space: pre-wrap;"><br>
</span></div>
<div><span style="font-size: 14px; white-space: pre-wrap;">I think, because of this may get the errors. Please anyone helps me to update my 'sys' to 64-bits integer value?</span></div>

<div class="PlainText">Hi!<br>
<br>
I don’t really understand why the array is of type int64 (and why that matters - are you on Python 2)?<br>
<br>
Can you try if this minimal example works for you:<br>
<br>
import mne<br>
import numpy as np<br>
<br>
X = np.random.rand(320, 60, 421)<br>
csd = mne.time_frequency.csd_array(X, 128)<br>
