How install tm1py to server that is not connected to internet?


Download python to your laptop and to the server, and install python on both.

Run the python-3.11.3-amd64.exe to install the software.

Select Customize installation. (ensure you click “add python to path” )

Click Next

Select install python for all users, and change the path to a simpler one outside program files.

Click Close when done.

On your laptop (that is connected to internet) go to your python folder. Inside the command prompt enter:

pip install tm1py[pandas]

When done – run below command, to ensure you have the requirements:  (

pip install requests_negotiate_sspi

Create the folder c:\temp\offline. Move to that folder in command window and run the command:

pip freeze > C:/temp/offline/requirements.txt

Zip all the needed files with this command (run the command from the folder where you want the zip files to be created):

pip download tm1py[pandas]

The versions above listed, depend on the version you have installed of python and tm1py. You may get different versions.

If you get errors later, in most cases, it is because we have not succeeded to get the right files to this folder.

Now copy the files over to the server from the laptop. (copy all files to the same folder)


Above a example of the req.txt file content for tm1py needed files.

Copy the whl files in c:\python311\scripts over to the servers c:\python311\scripts folder (or the folder you are using like c:\temp\offline).

If you copy between virtual machines, in vbox, you access the local host drive with \\Vboxsvr\c_drive\temp.

It is important that the files are in the same folder, otherwise you get:

Enter -vvv last to get more information about the issue;

pip install –no-index –find-links c:\python311\scripts -r requirements.txt -vvv

Maybe a solution, check what files you get issues with, if it is the files that end with tar.gz, then search on the laptop you have it installed on to find the whl file for the same function.  Search for mdxpy* if you get error at mdxpy-1.3.2.tar.gz.

You will find the file in a folder like C:\Users\Administrator\AppData\Local\pip\cache\wheels\f8\6d\90\4bfbb1a9cc872dbc6e440d1f4ec64cb896cc724e3a9d29fc92

copy the file mdxpy-1.3.2-py3-none-any.whl to the folder where you have the other files you need. (like c:\temp\offline)

Repeat for file TM1py-2.0.4-py3-none-any.whl, so you get a whl file from the cache to the other computer and place in the folder where you install from.

Try then again with the command similar to this:

c:\python312\scripts\pip install --no-index --find-links C:\tempd -r c:\tempd\req.txt

The clue is to have all the whl files you need in the folder where you install the things from.

If you get;

ERROR: Could not open requirements file: [Errno 2] No such file or directory: ‘requirements.txt’

Try this command after you copy the txt file to the scripts folder

C:\Python311\Scripts>pip install --no-index --find-links c:\python311\scripts -r requirements.txt -vvv


You can try to edit the txt file to have the number listed in the error, gives that the error goes away, but you get a new error.

C:\tempas>pip install –no-index –find-links c:\tempas\ -r requirements.txt

When you try to install several times to the same computer, think that the pip program will load files from the local cache folder first, and therefor the installation can fail – even you are writing the correct command to do the work.


== The last Solution to try are below ==

To repeat the steps you need to do to install a python package on a air-gapped computer:

On the computer where you have internet contact;

Install the latest python package (python-3.12.4-amd64.exe ), install the same package on the air-gapped computer.

Ensure that during installation you select, install for all users and add to path. Then go to the command prompt and run:

pip install tm1py[pandas] streamlit

pip freeze > c:/tempe/req.txt

Go to the tempe folder and run below command

pip download streamlit

pip download tm1py[pandas]

Here you get the gz file, but it looks like you need the whl file. Copy that from the cache to the c:\tempe folder. You may need these files:




So you have all needed whl files in the folder. The version number can be different if you install a different version of tm1py.

Copy the \tempe\ folder over to the air-gapped computer and run command:

c:\python312\scripts\pip install  --no-index  --find-links  C:\tempe  -r  c:\tempe\req.txt

Hopefully it works easier for you to do the installation on your computer. (Below when the pip command works fine).

To check if tm1py is installed enter: pip show tm1py

Add python to path by using the keyboard shortcut (Win+Pause) to get to settings and under advance link, click on “Environment Variables” button.

You can install streamlit via pip:

pip install streamlit

Once streamlit is installed, let us create a very basic web app.

As the first step, let us create a new Python script. Let us call it

Open in your favourite IDE or text editor, then add these lines:

import streamlit as st

With that in place, we can run Streamlit from the command line:

How to in a view only list the data rows for the last 3 years?


You need to have a column with the date in your fact table. If the date column in your fact table is a int, you have to join it with a date conversion table or use cast/convert.

We have used a date table (DM.dimdate).

The key_dimdate is a integer, and the date column is in the date format in SQL. The date format make it easy to compare it to a date question in SQL.

Create a SQL similar to this:

SELECT a.[Customer]
,a.[startDate] as [startDate]
,a.[endDate] as [endDate]
,a.[IsActive] as [IsActive]
FROM [DM].[facttable] a
inner JOIN [DM].[dimDate] f on a.[key_dimDate] = f.[key_dimDate]
where 1=1
and a.[IsActive] = 'Y'
-- and DATEADD(year, -3, GETDATE() ) < f.[Date] -- will list 3 years
and DATEADD(Quarter, -13, GETDATE() ) < f.[Date]  -- will list 39 months


If you get error like Column ‘id’ in field list is ambiguous, then you have missed to set the alias letter in front of all the columns references in the SQL query.

If you are getting an error: “Arithmetic overflow error converting expression to data type datetime.” Is that the F.Date in above SQL is a int, you have to convert it to a date somehow.

Only using CONVERT(DATETIME,[key_dimDate],103) can give overflow error.

Change the SQL to reflect your columns and tables.


More Information: 

Let’s say you need to add five months to current date, use this:

WHERE YourDate < DATEADD(month, 5, GETDATE())

I used function GETDATE() for getting current DateTime.

If you need to subtract some time, just add minus to second parameter:

WHERE YourDate < DATEADD(month, -5, GETDATE()) 


To see the SQL job log for a time period, try this in SQL server (will not work in Azure SQL)

@@SERVERNAME as ‘Server’, as ‘Job Name’,
jh.run_date as ‘Run Date’, jh.run_status as ‘Job Status’
FROM msdb.dbo.sysjobs j
SELECT ROW_NUMBER() OVER(PARTITION BY jh.job_id ORDER BY jh.run_date DESC) AS row_num, jh.*
FROM msdb.dbo.sysjobhistory jh
jh.step_id = 0 AND
jh.run_date >= CONVERT(varchar(8), DATEADD(DAY, -7, GETDATE()), 112) AND
jh.run_date <= CONVERT(varchar(8), GETDATE() + 1, 112)
–ORDER BY jh.run_date DESC
) AS jh ON jh.job_id = j.job_id
WHERE j.enabled = 1 AND jh.run_status = 0
ORDER BY, jh.run_date; 

Here are the different types of the JOINs in SQL:

  • (INNER) JOIN: Returns records that have matching values in both tables
  • LEFT (OUTER) JOIN: Returns all records from the left table, and the matched records from the right table
  • RIGHT (OUTER) JOIN: Returns all records from the right table, and the matched records from the left table
  • FULL (OUTER) JOIN: Returns all records when there is a match in either left or right table
