            Apparently, the fairseq folks decided to change the default branch of their GitHub repository from master to main exactly 7 days ago. (check this commit).

            So, adding the main branch to the repo info will fix the problem:

            How to create symbolic links for custom installation without root permission?
            Asked 2020-Dec-25 at 19:44

            First of all, I must say I'm not very comfortable with UNIX commands, shell language etc. I'm willing to install Google library SentencePiece (> https://github.com/google/sentencepiece), which is a dependency of a fairseq script to preprocess some speech data. I followed installation procedure as stated in the README.md from the git repo.

            I do not have root privileges, hence I couldn't install it the precognized way with cmake (meaning in /etc), and I had to install it in a custom directory. For the same reasons, as I do not have root privileges nor access to /etc directory, I couldn't execute the last line : sudo ldconfig -v. Trying the execution without sudo obviously returned a permission error. And now, if I try to call a function from SentencePiece, I get an error :

            generating segment labels for a Tensor given a value indicating segment boundaries
            Asked 2020-Dec-07 at 11:51

            Does anyone know of a way to generate a 'segment label' for a Tensor, given a unique value that represents segment boundaries within the Tensor?

            For example, given a 1D input tensor where the value 1 represents a segment boundary,

            x = torch.Tensor([5, 4, 1, 3, 6, 2])

            the resulting segment label Tensor should have the same shape with values representing the two segments:

            segment_label = torch.Tensor([1, 1, 1, 2, 2, 2])

            From the article (arxiv.org/pdf/1904.05862.pdf): "The output of the encoder is a low frequency feature representation zi ∈Z which encodes about 30 ms of 16 kHz of audio and the striding results in representations zi every 10ms." => The windows are overlapping and this explains why you are getting 2 frames fewer. Indeed we are moving a 30 ms window by 10ms steps. In your example, the 30 ms window takes 60 different positions.

            Apologies if this is a straightforward thing, I’m just not having luck getting answers online (and if this isn’t a good place to post).

            I’ve been trying to improve my Python, and I’ve been trying to make sense of some code for a Neural Network/Natural Language Processing package. I came across this:

            Answered 2020-May-10 at 23:50

            Empty sequences (e.g., lists, tuples, strings) evaluate to False. Non-empty sequences evaluate to True.

            args.encoder_layers_to_keep seems to be a string variable. An empty string "" evaluates to False, and a non-empty string evaluates to True.

            You can prove this to yourself by using the builtin function bool to convert to a boolean. Try bool("") and bool("foobar").

            This is suggested in the Python style guide (PEP8):

            For sequences, (strings, lists, tuples), use the fact that empty sequences are false:
