I tried running the example from https://www.fastestimator.org/examples/r1.2/image_classification/mnist/mnist on google colab
when i reach Model Construction
from fastestimator.architecture.tensorflow import LeNet
model = fe.build(model_fn=LeNet, optimizer_fn="adam")
It throws

Hi!
I'm not exactly sure if I'm posting on the correct place, please let me know if it is appropriate or not; greatly appreciate it!
My system is win10, with python 3.7 virtual environment.
I'm a new user to FastEstimator; when I was trying to run UNet lung segmentation example notebook, I get a keyerror when extracting the data; I was wondering if you could take a look, thanks a lot!

People saying that the latest torch fixed the incompatibility with TF:
Hello,
I want to try to use yolov5 in fastestimator to train model, what should my dataset look like?
such as:
.
│
├─Annotations
│ 1.xml
| 2.xml
| 3.xml
| ...
└─JPEGImages
1.jpg
2.jpg
3.jpg
...
Right?

I suppose this error occurs due to the latest release of albumentations
because pinning to albumentations==0.5.2
fixes it.
Hi,
I am wondering is there a way to filter CSVDataset class by keyword or value?

Experimenting with Fast Estimator.
I had trained a model using FE on a GPU instance(sagemaker).
I downloaded the saved .pt file and I am trying to create a python file for inferencing. The code is based on the Unet example on the Fastestimator site.
Since my laptop is CPU only, I am using the cpu docker image ( fastestimator/fastestimator:nightly-cpu).
I get the following error:
RuntimeError: Attempting to deserialize object on a CUDA device but torch.cuda.is_available() is False. If you are running on a CPU-only machine, please use torch.load with map_location=torch.device('cpu') to map your storages to the CPU.
for
model = fe.build(model_fn=lambda: UNet(input_size=(1, 512, 512)),
optimizer_fn=lambda x: torch.optim.Adam(params=x, lr=0.0001),
model_name="model_name",
weights_path=weights_path)
Could you let me know if I am missing anything ?
Use of multiprocessing.cpu_count() leads to inconsistent/unexpected results(slowdown) as .cpu_count() returns the total CPU's in the system and doesn't guarantee that the sub processes created will get allocated to the available CPU's.
There are two ways to handle this:
The current implementation is known to have failed and produce inconsistent results on different OS platforms/architectures
Link to issues when cpu_count() is used instead of actually cpu affinity

The requirement of an old scipy (1.4.1) that requires an old numpy is not compatible with the M1 architecture that requires a much higher numpy (1.21). It would work with scipy 1.8.0.
It would be nice to have it working in M1s as they are selling quite well.
Thanks!
