i am following the instruction in Readme to parse the data in lookAtPoint_EL using your pretrained models. i2mc extractor was successfully runned. But a error was raised, said “Changing the dtype to a subarray type is only supported if the total itemsize is unchanged”. I wonder if the version of my numpy(1.16.6) is improper。 Looking forward to your reply!

After properly formatting my data according to the internal data format used by irf, when I run the MATLAB script to extract the i2mc feature I get the following error.

nfile =

More info:

I used ./utils_lib/data_prep/augment.py script to prepare lookAtPoint_EL dataset for training.
It created 792 data for training and 396 for validation.
I followed your instruction and ran ./util_lib/I2MC-Dev/I2MC_rz.m in Matlab. It suppose to create 1188(792+ 296) i2mc file, but it only created 23 file. Why it’s only creating 23 file?.I think I am getting the above error because of that.

Can u tell me what I did wrong in Matlab? I edited the folder data as ‘……etdata/lookAtPoint_EL’
