I got an error when I do pip install "pyannote.audio==0.2.1"

Running setup.py bdist_wheel for pysndfile ... error

Failed building wheel for pysndfile

[bml1g12]

Don't know if its useful, but I think I also had this issue and resolved it after reading this forum post : ContinuumIO/anaconda-issues#7363

Which lead me to https://www.anaconda.com/blog/developer-blog/utilizing-the-new-compilers-in-anaconda-distribution-5/

which suggests you install the following packages:

gcc_linux-64
gxx_linux-64
gfortran_linux-64

After that I was libhdf5-dev and needed to download https://packages.ubuntu.com/xenial/amd64/libhdf5-10, and run a command like sudo cp /usr/lib/x86_64-linux-gnu/libhdf5_serial_hl.so.10 /usr/lib/x86_64-linux-gnu/libhdf5_hl.so.10

then I was good to go.
