.
background
The experimental environment is to use docker container in Ubuntu.
Trying to use torchviz to visualize the calculation graph of the DL model in the container, where torchviz has been installed based on the following instructions.
pip install torchviz
调用torchviz.make_dot可视化，出现报错，具体报错信息如下：
“
Traceback (most recent call last): File “/opt/conda/lib/python3.8/site-packages/graphviz/backend/execute.py”, line 81, in run_check
proc = subprocess.run(cmd, **kwargs) File “/opt/conda/lib/python3.8/subprocess.py”, line 493, in run

_execute_child
raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: PosixPath(‘dot’)
The above exception was the direct cause of the following exception:

raise ExecutableNotFound(cmd) from e graphviz.backend.execute.ExecutableNotFound: failed to execute PosixPath(‘dot’), make sure the Graphviz executables are on your systems’ PATH
”
.
solution
The error message indicated: "make sure the Graphviz executables are on your systems' PATH", and a search engine found similar problems .
The graphviz toolkit needs to be installed in the environment, the instructions are as follows:
apt-get install graphviz -y
If you can't find graphviz, update the source of apt and install it again:
apt-get update
apt-get install graphviz -y
Then the installation is successful, and the visualization function can be used normally!
Welcome to discuss in the comment area, I wish you a smooth calculation of the graph!
