3.2.7 编译Paddle模型
BMPADDLE是针对Paddle Paddle的模型编译器,可以将模型文件(inference.pdmodel,inference.pdiparams)编译成 BMRuntime 所需的文件。而且在编译的同时,可选择将每一个操作的NPU模型计算结果和CPU的计算结果进行对比,保证正确性。
命令行形式:
python3 -m bmpaddle [--model=<path>] \
[--input_names=<string>] \
[--shapes=<string>] \
[--descs=<string>] \
[--output_names=<string>] \
[--net_name=<name>] \
[--opt=<value>] \
[--dyn=<bool>] \
[--outdir=<path>] \
[--target=<name>] \
[--cmp=<bool>] \
[--mode=<string>] \
[--enable_profile=<bool>] \
[--list_ops]
参数介绍:
args
type
Description
model
string
Necessary.paddlepaddle model directory
input_names
string
Necessary.Set name of all network inputs one by one in sequence. Format “name1,name2,name3”
shapes
string
Necessary. Shapes of all inputs, default use the shape in prototxt, format [[x,x,x,x],[x,x],…], these correspond to inputs one by one in sequence
descs
string
Optional. Descriptions of inputs, format "[serial number, data type, lower bound, upper bound]", e.g., "[0, uint8, 0, 256]", default "[x, float, 0, 1]"
output_names
string
Necessary. Set name of all network outputs one by one in sequence. Format “name1,name2,name3”
net_name
string
Necessary. Name of the network
opt
int
Optional. Optimization level. Option: 0, 1, 2, default 1.
dyn
bool
Optional. Use dynamic compilation, default false.
outdir
string
Necessary. Output directory
target
string
Necessary. Option: BM1682, BM1684; default: BM1682
cmp
bool
Optional.Check result during compilation. Default: true
mode
string
Optional. Set bmpaddle mode. Option: compile, GenUmodel,summary, show, check. Default: compile.
enable_profile
bool
Optional. Enable profile log. Default: false
list_ops
Optional. List supported ops.
Python模式:
import bmpaddle
## compile fp32 model
bmpaddle.compile(
model = "/path/to/model(directory)", ## Necessary
outdir = "xxx", ## Necessary
target = "BM1684", ## Necessary
shapes = [[x,x,x,x],[x,x,x]], ## Necessary
net_name = "name", ## Necessary
input_names=["name1","name2"], ## Necessary, when .h5 use None
output_names=["out_name1","out_name2"], ## Necessary, when .h5 use None
opt = 2, ## optional, if not set, default equal to 1
dyn = False, ## optional, if not set, default equal to False
cmp = True, ## optional, if not set, default equal to True
enable_profile = True ## optional, if not set, default equal to False
)
若成功,输出的 log 最后会看到以下信息:
######################################
# Store bmodel of BMCompiler.
######################################
成功后,将在指定的文件夹中生成一个compilation.bmodel的文件,该文件则是转换成功的 bmodel,用户可以重命名。
