It is possible that your third party (./thirdparty/eigen) dose not be downloaded

[xhangHU]

I installed this, but this error is still reported..

I had a similar problem that I solved because I did not clone with --recursive. Even though the Eigen folder was there, the submodule was not cloned.

Is Eigen needed download by ourself? i cannot find download part in code

[rmadan2]

I solved this by using symbolic links to eigen3 in /usr/include

(DRD) ita:~/DROID-SLAM$ sudo python3 setup.py install
Traceback (most recent call last):
File "setup.py", line 2, in

ModuleNotFoundError: No module named 'torch'
But torch in installed , we can import torch

Another Error:

nvcc fatal : Unsupported gpu architecture 'compute_80'
error: command '/bin/nvcc' failed with exit code 1

PLz help me

For your 2nd error, after that it will work I think:

@pradyumnakulkarni87 what is the output of torch.cuda.get_arch_list()? after importing torch.
you need to comment some lines in setup.py:
if your GPU doesn't support compute_86 and compute_80 (which seems to be your case), comment out line no: 25, 26, 55, 56.
I found that in one of the issues earlier.

Thank you ! It works after Commenting ....Thank you
