Hi everyone, I’m working with PYNQ 2.7 on a ZCU104. I’m trying to run the tfc\_end2end\_example notebook from the FINN docker container. On cell 37 ```auto import numpy as np from finn.core.onnx_exec import execute_onnx input_dict = {iname: x.reshape(ishape)} ret = execute_onnx(model, input_dict) ``` I encounter the following error: ```auto --------------------------------------------------------------------------- FileNotFoundError Traceback (most recent call last) in 3 4 input_dict = {iname: x.reshape(ishape)} ----> 5 ret = execute_onnx(model, input_dict) /home/julien/finn/src/finn/core/onnx_exec.py in execute_onnx(model, input_dict, return_full_exec_context, start_node, end_node) 99 elif model_exec_mode == "remote_pynq": 100 # use remote exec metadata built into model to execute on a remote PYNQ --> 101 remote_exec(model, execution_context) 102 elif model_exec_mode == "rtlsim": 103 # use stitched IP for rtlsim /home/julien/finn/src/finn/core/remote_exec.py in remote_exec(model, execution_context) 116 process_scp_out = subprocess.Popen(bash_command, stdout=subprocess.PIPE) 117 process_scp_out.communicate() --> 118 outp = np.load("{}/output.npy".format(deployment_dir)) 119 execution_context[model.graph.output[0].name] = outp /opt/conda/lib/python3.8/site-packages/numpy/lib/npyio.py in load(file, mmap_mode, allow_pickle, fix_imports, encoding) 388 own_fid = False 389 else: --> 390 fid = stack.enter_context(open(os_fspath(file), "rb")) 391 own_fid = True 392 FileNotFoundError: [Errno 2] No such file or directory: '/tmp/finn_dev_julien/pynq_deployment_jremieh0/output.npy' ``` I have seen on another topic to try to execute driver.py via a ssh connexion ([output.npy not found in End-to-end-flow notebook · Issue #46 · Xilinx/finn · GitHub](https://github.com/Xilinx/finn/issues/46)). When I do so I have the following error: ```auto xilinx@pynq:~/finn_dev_julien/pynq_deployment_isqt422a$ sudo python3 driver.py [sudo] password for xilinx: Traceback (most recent call last): File "driver.py", line 34, in from driver_base import FINNExampleOverlay File "/home/xilinx/finn_dev_julien/pynq_deployment_isqt422a/driver_base.py", line 32, in from pynq import Overlay, allocate ModuleNotFoundError: No module named 'pynq' ``` So I tried to install pynq (even tho it sounded weird): ```auto xilinx@pynq:~/finn_dev_julien/pynq_deployment_isqt422a$ pip3 install pynq Defaulting to user installation because normal site-packages is not writeable Requirement already satisfied: pynq in /usr/local/share/pynq-venv/lib/python3.8/site-packages (2.7.0) Requirement already satisfied: cffi in /usr/local/share/pynq-venv/lib/python3.8/site-packages (from pynq) (1.14.5) Requirement already satisfied: numpy in /usr/local/share/pynq-venv/lib/python3.8/site-packages (from pynq) (1.20.3) Requirement already satisfied: pandas in /usr/local/share/pynq-venv/lib/python3.8/site-packages (from pynq) (1.3.3) Requirement already satisfied: setuptools>=24.2.0 in /usr/local/share/pynq-venv/lib/python3.8/site-packages (from pynq) (44.0.0) Requirement already satisfied: pycparser in /usr/lib/python3/dist-packages (from cffi->pynq) (2.19) Requirement already satisfied: pytz>=2017.3 in /usr/lib/python3/dist-packages (from pandas->pynq) (2019.3) Requirement already satisfied: python-dateutil>=2.7.3 in /usr/lib/python3/dist-packages (from pandas->pynq) (2.7.3) WARNING: You are using pip version 21.2.1; however, version 22.2.1 is available. You should consider upgrading via the '/usr/local/share/pynq-venv/bin/python3 -m pip install --upgrade pip' command. ``` Does anyone know what could I do to solve this problem? Thanks in advance, Julien ---

Hi, After more research I found these Github issues but their solutions didn’t work for me : - [execute\_onnx() in cnv\_end2end\_example throws error · Issue #282 · Xilinx/finn · GitHub](https://github.com/Xilinx/finn/issues/282) - [execute\_onnx() in tfc\_end2end\_example throws error · Issue #275 · Xilinx/finn · GitHub](https://github.com/Xilinx/finn/issues/275) bistring and setuptools are installed on my board: ```auto xilinx@pynq:~$ pip3 install bitstring setuptools Defaulting to user installation because normal site-packages is not writeable Requirement already satisfied: bitstring in /usr/local/share/pynq-venv/lib/python3.8/site-packages (3.1.9) Requirement already satisfied: setuptools in /usr/local/share/pynq-venv/lib/python3.8/site-packages (44.0.0) WARNING: You are using pip version 21.2.1; however, version 22.2.1 is available.

Anyway, `output.npy` doesn’t exist there either: ```auto xilinx@pynq:~/finn_dev_julien/pynq_deployment_1g5ct2f0$ ls driver_base.py finn qonnx resizer.hwh validate.py driver.py input.npy resizer.bit runtime_weights ``` ---

Hi @julienmas, Welcome to our community. pynq is installed in a venv, which is not available in the xilinx user by default. I would recommend you login as sudo. To source the venv, please check this > [@How to use Kria-PYNQ from the command line?](https://discuss.pynq.io/t/how-to-use-kria-pynq-from-the-command-line/3723/2): > > Hi there, This is probably because from v2.7 we are running inside a virtual environment. Instead of running python in sudo try: sudo -i source /etc/profile.d/pynq\_venv.sh python3 Thanks Shawn Mario ---

Hi Mario, Thanks for your answer. When I log as root I can’t find `driver.py`: ```auto xilinx@pynq:~/finn_dev_julien$ sudo -i [sudo] password for xilinx: root@pynq:~# ls root@pynq:~# ``` I used the the venv with the xilinx user, it didn’t help me either: ```auto xilinx@pynq:~/finn_dev_julien/pynq_deployment_599kb_zv$ source /etc/profile.d/pynq_venv.sh (pynq-venv) xilinx@pynq:~/finn_dev_julien/pynq_deployment_599kb_zv$ sudo python3 driver.py Traceback (most recent call last): File "driver.py", line 34, in from driver_base import FINNExampleOverlay File "/home/xilinx/finn_dev_julien/pynq_deployment_599kb_zv/driver_base.py", line 32, in from pynq import Overlay, allocate ModuleNotFoundError: No module named 'pynq' (pynq-venv) xilinx@pynq:~/finn_dev_julien/pynq_deployment_599kb_zv$ ``` ---

Have you tried to run your script from a terminal inside JupyterLab? > When I log as root I can’t find `driver.py` You need to move to the directory where the file is. Mario ---

Thanks, I’ve been able to run `driver.py` from a terminal inside JupyterLab: ```auto (pynq-venv) root@pynq:/home/xilinx/finn_dev_julien/pynq_deployment_599kb_zv# python3 driver.py (pynq-venv) root@pynq:/home/xilinx/finn_dev_julien/pynq_deployment_599kb_zv# ``` However, it didn’t solved my initial problem: I’m still unable to run `execute_onnx()` from the FINN Jupyter Notebook. ---

I would suggest you seek support in the FINN forums. Mario ---

It now works, using PYNQ 2.6. I’m not sure what I’ve done, but I think it started to worked after I did a `git pull` from FINN Github repo, on dev branch.
