Installing on colab

[ghost]

I tried to install warp_ctc on colab

but when I tried to install as your direction I got some error like this:

Is there anyone install it on colab???

plz give me some any advice.

I managed to install it. !git clone https://github.com/SeanNaren/warp-ctc.git !cd warp-ctc; mkdir build; cd build; cmake ..;make !cd warp-ctc/pytorch_binding;python setup.py install

then I restart the runtime to reload the module.

what's mean that I restart the runtime to reload the module.how to do.

[Anubhav007]

After doing the setup from https://github.com/SeanNaren/warp-ctc Install ctc from baidu to get .so file

• pip install torch-baidu-ctc Copy the _warp_ctc.cpython-36m-x86_64-linux-gnu.so to warp-ctc/pytorch_binding/warpctc_pytorch by using this command
• cp /usr/local/lib/python3.6/dist-packages/torch_baidu_ctc/_C.cpython-36m-x86_64-linux-gnu.so /content/warp-ctc/pytorch_binding/warpctc_pytorch Press ctrl+M on colab to restart runtime.
