TF1.x导出的pb模型无法通过x2paddle转换为paddlelite可以运行的模型

[combohehe]

conda activate paddlelite37
pio uninstall requests -y
pip install requests
pip uninstall paddlepaddle -y

下载 PaddlePaddle CPU 2.5.2 wheel

pip install paddlepaddle==2.5.2 -f https://www.paddlepaddle.org.cn/whl/linux/mkl/avx/stable.html
python -V
pip uninstall protobuf -y
pip install protobuf==3.20.3
pip uninstall tensorflow -y
pip install tensorflow==1.15.5

pip install paddlelite==2.12

pip uninstall x2paddle -y
pip install x2paddle
pio uninstall six -y
pip install six
x2paddle --framework=tensorflow --model=hed_lite_model.pb --save_dir=pd_model_lite会报错%%bash
source /root/miniconda3/etc/profile.d/conda.sh
conda activate paddlelite37
pio uninstall requests -y
pip install requests
pip uninstall paddlepaddle -y

下载 PaddlePaddle CPU 2.5.2 wheel

python -V
pip uninstall protobuf -y
pip install protobuf==3.20.3
pip uninstall tensorflow -y
pip install tensorflow==1.15.5

pip uninstall x2paddle -y
pip install x2paddle
pio uninstall six -y
pip install six
x2paddle --framework=tensorflow --model=model.pb --save_dir=pd_model_lite
报错 python>=3.8 is required。但是使用3.8之后仍然报错ERROR: No matching distribution found for tensorflow==1.15.5
