安装tensorrt 下载失败cutlass(安装tensorflow2.0)

1、我是手动安装，需要自己去官网下载对应的tar安装包，解压

tar xvf TensorRT-6.0.1.8.Ubuntu-18.04.x86_64-gnu.cuda-10.2.cudnn7.6.tar.gz

2、激活自己的虚拟环境

source activate faster-rcnn

3、安装

cd python
# 安装别的版本，我会报错说版本不对
pip install tensorrt-6.0.1.8-cp36-none-linux_x86_64.whl

4、拷贝

sudo mkdir -p /usr/lib/tensorrt
cd ..
sudo cp -a lib/* /usr/lib/tensorrt
source ~/.bashrc

5、安装torch2trt
torch2trt代码地址

cd torch2trt
python setup.py install

python
import tensorrt

不报错即可

6、随后自己照着README文档测试了一下，确实没问题。
会有如下警告UserWarning: Named tensors and all their associated APIs are an experimental feature and subject to change. Please do not use them for anything important until they are released as stable.因为pytorch版本不对，忽略即可。

7、之后加速YOLOP的，不过会出现如下错误：
Warning: Encountered known unsupported method torch.nn.functional.has_torch_function_unary
Warning: Encountered known unsupported method torch.nn.functional.hardtanh
Warning: Encountered known unsupported method torch.Tensor.to
应该是tensorrt不支持这几个函数，需要自己写一下转换文件，目前还没解决这个问题，希望有懂哥知道的话能指导指导～
