can you post the full error traceback please? Meanwhile, try updating numpy and see if the problem persists.
Hi, I also encountered the same issue as @yaniferhaoui had. I tried updating numpy to version 1.19.1 but the issue still persists. Here is my full error traceback.
Traceback (most recent call last):

self.X = dataset[:,0]
IndexError: too many indices for array: array is 1-dimensional, but 2 were indexed
Thank you.
Hi, may I know whether you have the solution to this error. I am also getting the same error.
Thanks
I printed the dataset
shape, it is (0,). This is an empty dataset. Note that the code in the main pipeline is as follows:
run_MCTS(args, start_idx=0, iteration=i)
train_connectnet(args, iteration=i, new_optim_state=True)
the error in train_connectnet() originates from the empty results of run_MCTS(). Apparently, the MCTS is not working.

The above phenomenon happened because I actually had a mismatch problem of NVIDIA NVML:
THCudaCheck FAIL file=/opt/conda/conda-bld/pytorch_1579022060824/work/aten/src/THC/THCGeneral.cpp line=50 error=804 : forward compatibility was attempted on non supported HW
Solved it by rebooting. The code now works like a magic.

Hello, I have a trouble during the first run:
python3 main_pipeline.py
I get :
"alpha_net_c4.py", line 14, in __init__ self.X = dataset[:,0] IndexError: too many indices for array
Someone can help me ? Thanks for your time
