float' object cannot be interpreted as an integer

[Twinkle123321]

Hi,when I run the code,it shows as following:
Loading data...
Generating images...
Traceback (most recent call last):
File "C:/Users/Guo/Desktop/EEGLearn-master/eeglearn/eeg_cnn_lib.py", line 473, in
av_feats = reduce(lambda x, y: x+y, [feats[:, i*192:(i+1)*192] for i in range(feats.shape[1] / 192)])
TypeError: 'float' object cannot be interpreted as an integer

so I modify the part of line 473 as" (feats.shape[1] //192)" ,it shows:
Loading data...
Generating images...
Traceback (most recent call last):
File "C:/Users/Guo/Desktop/EEGLearn-master/eeglearn/eeg_cnn_lib.py", line 477, in
32, normalize=False)
File "C:/Users/Guo/Desktop/EEGLearn-master/eeglearn/eeg_cnn_lib.py", line 67, in gen_images
for c in range(n_colors):
TypeError: 'float' object cannot be interpreted as an integer

would you give me some suggestions?thank you

What data are you trying to load? Is it the sample_data or another dataset?

[Twinkle123321]

wow,thank you to answer my question,I'm trying to load the sample_data
should code be supported by GPU?

[pbashivan]

Code should be runnable on GPU.
I can't recreated the error on my end. What's the shape of feats?

sorry，when I update the version of Keras,it could run successful,thank you!
I want to ask another very simple math question of code:
def azim_proj(pos):
[r, elev, az] = cart2sph(pos[0], pos[1], pos[2])
return pol2cart(az, m.pi / 2 - elev)
function pol2cart(theta,rho) 's second param should be radius,but "m.pi / 2 - elev" is a angle,how it works?

[pbashivan]

We actually ignore r because we assume that all points are located on a sphere. Azimuthal equidistance projection keeps retains the distance between points on the sphere to a fixed point (e.g. north pole on earth map) while projecting down to 2D. So pi/2 - elevation is the true measure of distance between the fixed point and every other point. This is the conceptual reason why pi/2 - elevation is used as r. Some math related to this is discussed in here

OK，thank you very much

Because the author uses 2.7 python and you use 3.5 python, you have to change'' to'\'
