AttributeError: 'bytes' object has no attribute 'encode'

I'm on ubuntu16.04 anaconda python3.6
after executing the below commands:
CUDA_VISIBLE_DEVICES=0 python learning/main.py --dataset sema3d --SEMA3D_PATH /home/sdc/dataset/semantic3d --db_test_name testred --db_train_name trainval --epochs 500 --lr_steps '[350, 400, 450]' --test_nth_epoch 100 --model_config 'gru_10,f_8' --ptn_nfeat_stn 11 --nworkers 2 --odir "results/sema3d/trainval_best"
got the error below:

For bo
For the first error, I knowed it need to encode and decode between string and bytesin python3, so I vim the interface.py

 51  def encode_str(s):
 52      if is_python2:
 53          return s
 54      return s.encode("utf-8")

I think the code snippet is right. For the two errors, I have searched, but all of them I think are helpless. Could tell me waht's the py version you utilize? or maybe paste the your compiler.py and interface.py please

I should add that for the second error, From here I learned that it's for python2, but your python version is 3.6. So I'm confused that how you can run the code

Hi,

this seems to be an error a few other people are encountering. It was solved in this issue and this one.

Let me know if it doesn't work for you.

This was caused by recently merged NVIDIA/pynvrtc#2 and fixed here today - 44bcbe8

@loicland thankyou, by your guide, I have successfully solved the issue. @mys007 that's it
