Installation error with cpuonly

[lnalborczyk]

Hi, I am trying to install warpctc-pytorch as part of ESPnet (following the install guide here).

However, I can not install warpctc-pytorch on my machine... when I am trying to build ESPnet with make, I get the following error:

When I try to manually install warpctc-pytorch, I also get this error:

python3 -m pip install warpctc-pytorch==0.2.1+torch16.cpu

ERROR: Could not find a version that satisfies the requirement warpctc-pytorch==0.2.1+torch16.cpu (from versions: none)
ERROR: No matching distribution found for warpctc-pytorch==0.2.1+torch16.cpu

I understand that the version I am trying to install does not exist... but how can I install warpctc-pytorch for a CPU-only usage?

Thank you in advance.

Your environment is MacOSX? MaxOSX is not supported.
Write your environment more.

[lnalborczyk]

Thank you for your prompt answer.

Yes it is MacOSX (Catalina v10.15.4). Does it mean I can not install/use ESPnet?

What do you mean by "write your environment more"?

[kamo-naoyuki]

It's general caution at github.

Then, you can't install espnet using the Makefile.

[lnalborczyk]

Well, as said above, I also tried to install warp-ctc directly (i.e., not using the Makefile) using python3 -m pip install warpctc-pytorch==0.2.1+torch16.cpu, which does not seem to work...

[kamo-naoyuki]

See warpctc-pytorch at pypi. It's not distributed for mac.
Try install manually.
