I believe it should be "Research".
Hello, thanks for open-sourcing such a well structured code!
I am currently having trouble with trying to download the pre-processed data shared on globus.
Even after logging in, it seems like the download button is disabled. Has anything changed with the permission? What can I do to fix this? Below is the screenshot of what I am facing.
Thanks for your amazing work! I want to reproduce your result on lower resolution but I get really bad result on 64*32. How should I change settings?
Hello! I can't understand the calculation method in FFT.
o1_real = x.real * w1[0] - x.imag * w1[1] + b1[0]
o1_imag = x.imag * w1[0] + x.real * w1[1] + b1[1]
o2_real = o1_real * w2[0] - o1_imag * w2[1] + b2[0]
o2_imag = o1_imag * w2[0] + o2_real * w2[1] + b2[1]
Why should the real be '-', '+', '+', the imag be '+', '+', '+'? What role does this calculation combination play in it? Can I change the first '-' to '+' or vice versa?
And what role does 'kept_modes' play in it? Dropout?
When I try to run the.grib file, the output image is displayed with an error:cfgrib.dataset.DatasetBuildError: key present and new value is different: key='surface' value=Variable(dimensions=(), data=0.0) new_value=Variable(dimensions=(), data=2.0),How to solve the problem that the predicted result differs greatly from the actual value
I have a question about inference. Is there a part for generating prediction files? I couldn't find it. What I got were some performance metrics of the predictions.I mean, the various meteorological data of the predictions.
I have a very general question, which is not clear to me, about this method. and sorry if my question is very basic because I am a noobie in this field.
I ran the code and got the results for the same datasets used inside the paper (ERA5 res 30km) for different dates.
Can I use higher res data (2km) for the smaller area too? and need to train the whole model from the scratch or I can use the checkpoints provided in the paper to run the code for higher-resolution datasets?
Thank you very much for your time! :)
Hello,
It will be good to have a relatively smaller dataset for experimentation/learning purposes. By smaller, it may be low spatial resolution, smaller time-period, lesser number of variables etc.
I do not have an organization and log into globus through personal identity.
I came across with network issue with personal endpoint. I wonder if there is other place, google cloud drive for example, to download the pretrained model file?
Hello everyone. I have an issue with the TP acc which is extremely low. does anyone know what can be the problem? below you can find the output after an inference and my input data info:

Hi,
I was looking to perform inference on the trained model and noticed that the download option was not available in the Globus App. Could someone please look into this.
Thanks,
Vignesh
Thank you for your great code, this is SOTA model.
I had an issue with running the pre-processing parallel_copy.py or MPI.py (similar to parallel_copy.py but it's has different number of years) by running the exact datasets for full year(2016-2021) and still got the error which is: KeyError "ValueError: h5py was built without MPI support, can't use mpio driver"
I installed OpenMPI, mpi4py

I just started using mpi4py and h5py, could you please help me to run the prepossessing parallel_copy.py
Regarding the pre-trained weight file backbone.ckpt, is this the weight file of the afno_backbone stage or the weight file of the afno_backbone_finetune stage? I will be extremely grateful for your prompt reply.
First of all, thank you for your GREAT code, it is a real game changer.
I had an issue with running the pre-processing stage by running the exact datasets used inside the written example code in this stage (13 days) and still got the error which is: KeyError "Unable to open object (object 'fields' doesn't exist)"
I don't know what causes this problem because in my point of view everything must be ok with the code and datasets.
thank you for releasing this amazing repo!
I found the reason for the error - it has do with the number of in_channels
specified in the AFNO.yaml
file
I changed in_channels
to [0, 1, 2]
and I don't get the error now
I'm closing this issue, but it'd be great if someone could give me some insight or add a short note on the changes to be made to run train the model on smaller h5 files
thank you again for releasing the repo - I look forward to understanding the code better :)
==================
I'm able to run train.py
with the large h5 files available on Globus.
When I try to run train.py
with the smaller h5 files (regional or era5_subsample) made available on the NERSC portal, the following line throws an error:
https://github.com/NVlabs/FourCastNet/blob/master/utils/data_loader_multifiles.py#L207
specifically:
self.files[year_idx][(local_idx-self.dt*self.n_history):(local_idx+1):self.dt, self.in_channels]
throws the following error

for the smaller h5 files on NERSC - regional or era5_subsample is

I'm not very familiar with h5py yet - could someone please help me edit the code on https://github.com/NVlabs/FourCastNet/blob/master/utils/data_loader_multifiles.py#L207 so I can run train.py
on the smaller h5 files .
is there some edit to the AFNO.yaml
besides the file paths that needs to be made to train the model on smaller h5 files?
thank you! @jdppthk @MortezaMardani
