error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 - Colab

[francescoromito]

Hello!

i'm trying to test this amazing architecture on google colab and I've only used the commands on the github guide. I post them to be clear

!git clone https://github.com/dvlab-research/Stratified-Transformer.git !pip install -r /content/Stratified-Transformer/requirements.txt !python3 /content/Stratified-Transformer/lib/pointops2/setup.py install

The third returns the error in the title but it is raised by the following: "x86_64-linux-gnu-gcc: error: src/pointops_api.cpp: No such file or directory"

To be clear at most I write all the output of the line 3:

How can I solve?

The pointops_api.cpp is in the src/ directory. Can you try this: cd /content/Stratified-Transformer/lib/pointops2/ && python setup.py install ?

[francescoromito]

Thank you! It solves a bit but still it can't finish compiling because yelds another error

[X-Lai]

You environment may lack THC.h. I haven't met that before, so you can search which package contain it and install it.

@francescoromito In all .cpp files within lib\ comment out #include <THC/THC.h>. Apparently, this is an old file thats not included with PyTorch anymore and its not needed.
