To Reproduce
gluonnlp version 1.0.0.dev20210116
mxnet version 1.7.0.post1
fairseq version 1.0.0a0+4a6f89d
bash convert_roberta.sh
@jumpily You may need to install MXNet 2.0 and try again. You can try out the following commands:
# Install the version with CUDA 10.1
python3 -m pip install -U --pre "mxnet-cu101>=2.0.0b20201206" -f https://dist.mxnet.io/python
# Install the version with CUDA 10.2
python3 -m pip install -U --pre "mxnet-cu102>=2.0.0b20201206" -f https://dist.mxnet.io/python
# Install the version with CUDA 11
python3 -m pip install -U --pre "mxnet-cu110>=2.0.0b20201206" -f https://dist.mxnet.io/python
# Install the cpu-only version
python3 -m pip install -U --pre "mxnet>=2.0.0b20201206" -f https://dist.mxnet.io/python@sxjscience That seems to have worked, thank you! Are the converted models compatible with lower MXNet versions?
No, they are not.
