IndexError: list index out of range

[fauzivy]

Hi. I just started to use the dataset but I got problem while following readme. By having this issue I am unable to download the data using the links provided in mmdatasdk.cmu_mosi.highlevel from the code below:

cmumosi_highlevel=mmdatasdk.mmdataset(mmdatasdk.cmu_mosi.highlevel,'cmumosi/')

I tried to read some other issues but still can't manage to find the solution. I hope by raising this issue will solve the problem and might help others who experience the same problem too. Thank you.

The output error is shown here:

I also encountered the same problem,is your system is also Windows？Hope to get a solution

[fauzivy]

@bourne-3 yes, mine is Windows, and still haven't solved it yet

Hi @fauzivy @bourne-3,

I have never tried the sdk on windows. However based on the error it seems a problem when trying to figure out the path. Seems like if os.path.isdir(destination.rsplit(os.sep,1)[-2]) is False: does not have a consistent behavior between linux and windows. Any chance you can migrate to linux?

[fauzivy]

Thank you @A2Zadeh for the explanation but unfornately I'm not capable to migrate to Linux. Any other suggestion?

[npurson]

It is because that the os.sep under Windows is actually \\ rather than / under Linux. The solution is simply replace the os.sep with '/' in the following 2 pieces of code:

1. mmsdk\mmdatasdk\computational_sequence\download_ops.py, line 15:

if os.path.isdir(destination.rsplit(os.sep, 1)[-2]) is False:
    os.mkdir(destination.rsplit(os.sep, 1)[-2])

2. mmsdk\mmdatasdk\computational_sequence\computational_sequence.py, line 70:

elif '.csd' not in destination:
    destination=os.path.join(destination, resource.split(os.sep)[-1])

Thank you @npurson. It worked for me.
