[Errno2] No such file or directory


Hello everybody,

I'm trying to creat a simple groundwatermodel and I use the package flopy. 

Python should calculate some things and the results should represented as a figure.

import flopy
import numpy as np
import matplotlib.pyplot as plt
import flopy.utils.binaryfile as bf

# Assign name and create modflow model obj

filename = 'tutorial1'
mf = flopy.modflow.Modflow(filename, exe_name='mf2005')

# Model domain and grid definition
Lx = 1000
Ly = 1000
ztop = 0
zbot = -50
nlay = 1
nrow = 10
ncol = 10
delr = Lx/ncol
delc = Ly/nrow
delv = (ztop-zbot)/nlay
botm = np.linspace(ztop, zbot, nlay+1)

# create the discretization object
dis = flopy.modflow.ModflowDis(mf, nlay, nrow, ncol, delr=delr, delc=delc, top=ztop, botm=botm[1:])

# Variables fpr BAS Package
ibound = np.ones((nlay, nrow, ncol), dtype=np.int32)
ibound[:, :, :0] = -1
ibound[:, :, :-1] = -1
strt = np.ones((nlay, nrow, ncol), dtype=np.float32)
strt[:, :, 0] = 10
strt[:, :, -1] = 0
bas = flopy.modflow.ModflowBas(mf, ibound=ibound, strt=strt)

# Layer-Property
lpf = flopy.modflow.ModflowLpf(mf, hk=10., vka=10., ipakcb=53)

# output
spd = {(0, 0): ['print head', 'print budget', 'save head', 'save budget']}
oc = flopy.modflow.ModflowOc(mf, stress_period_data=spd, compact=True)

# Gradient
pcg = flopy.modflow.ModflowPcg(mf)


# grafic
plt.subplot(1, 1, 1, aspect='equal')
hds = bf.HeadFile(filename+'.hds')
head = hds.get_data(totim=1.0)
levels = np.arange(1,10,1)
extent = (delr/2., Lx - delr/2., Ly - delc/2., delc/2.)
plt.contour(head[0, :, :], levels=levels, extent=extent)

Unfortunately after running the skript I get following message:

Traceback (most recent call last):
  File "C:/Users/Johannes/PycharmProjects/getting_started/tutorial1.py", line 50, in <module>
    hds = bf.HeadFile(filename+'.hds')

    precision = get_headfile_precision(filename)

    f = open(filename, 'rb')
FileNotFoundError: [Errno 2] No such file or directory: 'tutorial1.hds'

Process finished with exit code 1


Has anybody an idea or maybe a solution for this problem?

BTW: I didn't creat it by my own. Actually it is a simply tutorial. ;)

Thanks for your help



Hi Physiker,

Thank you for contacting PyCharm support.

Have you tried to run this code outside of PyCharm?

Are you getting the same error?

Kind regards,




Hello Sergey,

thanks for your answer.

Yes I did it. And it doesn't work too.

But in the meantime I have found my mistake. The exe-file 'mf2005' wasn't in the right directory path. So it work now. :)

Well, I'm just a beginner. :D

Thanks for your help.


Alright thanks for letting me know :)

Kind regards,
