pip install pocketsphinx MemoryError

[yuzhiguo07]

When I use pip to install pocketsphinx, the system always report an error:"MemoryError". I tried to add "--no-cache-dir " behind "pip install pocketsphinx", but it also killed.

root@ReSpeaker:~# pip install pocketsphinx --no-cache-dir Collecting pocketsphinx Downloading pocketsphinx-0.1.3.zip (29.3MB) 100% |################################| 29.3MB 191kB/s Killed

Is this an issue about running out of memory? How could I solve this problem

pocketsphinx is already installed on respeaker by default. You don't have to re-install it. pocketsphinx needs to be cross-compiled.

ok, but when I run a test file, the system told me that there is an USBError.

It's likely that the device have been used by other program. Try /etc/init.d/mopidy disable && /etc/init.d/mopidy stop
