Load the model
Load the pretrained model from huggingface
from transformers import AutoModel<br /> flowformer = AutoModel.from_pretrained("matth/flowformer", trust_remote_code=True)<br />
trust_remote_code=True
is necessary because the model code uses a custom architecture.
Usage
The model expects as input a pytorch tensor x
with shape batch_size x num_cells x num_markers
.
The pretrained model is trained with the the markers: TIME, FSC-A, FSC-W, SSC-A, CD20, CD10, CD45, CD34, CD19, CD38, SY41. If you use different markers (or a different ordering of markers), you need to specify this by setting the markers
kwarg in the model forward pass:
output = flowformer(x, markers=["Marker1", "Marker2", "Marker3"])<br />
For more information about model usage as well as hands-on examples check out this demo notebook from my colleague Florian Kowarsch: https://github.com/CaRniFeXeR/python4FCM_Examples/blob/main/hyperflow2023.ipynb
